This is necessary to generate meaningful project file names in \fI\%Xcode\fP and \fI\%Visual Studio Generators\fP IDE generators. It also allows the target names to be referenced unambiguously. .sp Makefile generators are capable of supporting duplicate \fI\%add_custom_target()\fP names. For projects that care only about \fI\%Makefile Generators\fP and do not wish to support \fI\%Xcode\fP or \fI\%Visual Studio Generators\fP IDE generators, one may set this property to \fBTrue\fP to allow duplicate custom targets. The property allows multiple \fI\%add_custom_target()\fP command calls in different directories to specify the same target name. However, setting this property will cause non\-Makefile generators to produce an error and refuse to generate the project. .SS AUTOGEN_SOURCE_GROUP .sp New in version 3.9. .sp Name of the \fI\%source_group()\fP for \fI\%AUTOMOC\fP, \fI\%AUTORCC\fP and \fI\%AUTOUIC\fP generated files. .sp Files generated by \fI\%AUTOMOC\fP, \fI\%AUTORCC\fP and \fI\%AUTOUIC\fP are not always known at configure time and therefore can\(aqt be passed to \fI\%source_group()\fP\&. \fBAUTOGEN_SOURCE_GROUP\fP can be used instead to generate or select a source group for \fI\%AUTOMOC\fP, \fI\%AUTORCC\fP and \fI\%AUTOUIC\fP generated files. .sp For \fI\%AUTOMOC\fP, \fI\%AUTORCC\fP and \fI\%AUTOUIC\fP specific overrides see \fI\%AUTOMOC_SOURCE_GROUP\fP, \fI\%AUTORCC_SOURCE_GROUP\fP and \fI\%AUTOUIC_SOURCE_GROUP\fP respectively. .SS AUTOGEN_TARGETS_FOLDER .sp Name of \fI\%FOLDER\fP for \fB*_autogen\fP targets that are added automatically by CMake for targets for which \fI\%AUTOMOC\fP is enabled. .sp If not set, CMake uses the \fI\%FOLDER\fP property of the parent target as a default value for this property. See also the documentation for the \fI\%FOLDER\fP target property and the \fI\%AUTOMOC\fP target property. .SS AUTOMOC_SOURCE_GROUP .sp New in version 3.9. .sp Name of the \fI\%source_group()\fP for \fI\%AUTOMOC\fP generated files. .sp When set this is used instead of \fI\%AUTOGEN_SOURCE_GROUP\fP for files generated by \fI\%AUTOMOC\fP\&. .SS AUTOMOC_TARGETS_FOLDER .sp Name of \fI\%FOLDER\fP for \fB*_autogen\fP targets that are added automatically by CMake for targets for which \fI\%AUTOMOC\fP is enabled. .sp This property is obsolete. Use \fI\%AUTOGEN_TARGETS_FOLDER\fP instead. .sp If not set, CMake uses the \fI\%FOLDER\fP property of the parent target as a default value for this property. See also the documentation for the \fI\%FOLDER\fP target property and the \fI\%AUTOMOC\fP target property. .SS AUTORCC_SOURCE_GROUP .sp New in version 3.9. .sp Name of the \fI\%source_group()\fP for \fI\%AUTORCC\fP generated files. .sp When set this is used instead of \fI\%AUTOGEN_SOURCE_GROUP\fP for files generated by \fI\%AUTORCC\fP\&. .SS AUTOUIC_SOURCE_GROUP .sp New in version 3.21. .sp Name of the \fI\%source_group()\fP for \fI\%AUTOUIC\fP generated files. .sp When set this is used instead of \fI\%AUTOGEN_SOURCE_GROUP\fP for files generated by \fI\%AUTOUIC\fP\&. .SS CMAKE_C_KNOWN_FEATURES .sp New in version 3.1. .sp List of C features known to this version of CMake. .sp The features listed in this global property may be known to be available to the C compiler.

CMake provided some individual compile features to help projects determine whether specific features were available. These individual features are now less relevant and projects should generally prefer to use the high level meta features instead. Individual compile features are not provided for C++ 17 or later. .sp See the \fI\%cmake\-compile\-features(7)\fP manual for further discussion of the use of individual compile features. .SS

The property is set to true on OpenBSD and false on other platforms. .SS GENERATOR_IS_MULTI_CONFIG .sp New in version 3.9. .sp Read\-only property that is true on multi\-configuration generators. .sp True when using a multi\-configuration generator such as: .INDENT 0.0 .IP \(bu 2 \fI\%Ninja Multi\-Config\fP .IP \(bu 2 \fI\%Visual Studio Generators\fP .IP \(bu 2 \fI\%Xcode\fP .UNINDENT .sp Multi\-config generators use \fI\%CMAKE_CONFIGURATION_TYPES\fP as the set of configurations and ignore \fI\%CMAKE_BUILD_TYPE\fP\&. .SS GLOBAL_DEPENDS_DEBUG_MODE .sp Enable global target dependency graph debug mode. .sp CMake automatically analyzes the global inter\-target dependency graph at the beginning of native build system generation. This property causes it to display details of its analysis to stderr. .SS GLOBAL_DEPENDS_NO_CYCLES .sp Disallow global target dependency graph cycles. .sp CMake automatically analyzes the global inter\-target dependency graph at the beginning of native build system generation. It reports an error if the dependency graph contains a cycle that does not consist of all STATIC library targets.

The \fBJOB_POOLS\fP property is a semicolon\-separated list of pairs using the syntax \fBNAME=integer\fP (without a space after the equality sign). .sp For instance: .INDENT 0.0 .INDENT 3.5 .sp .EX set_property(GLOBAL PROPERTY JOB_POOLS two_jobs=2 ten_jobs=10) .EE .UNINDENT .UNINDENT .sp Defined pools could be used globally by setting \fI\%CMAKE_JOB_POOL_COMPILE\fP and \fI\%CMAKE_JOB_POOL_LINK\fP or per target by setting the target properties \fI\%JOB_POOL_COMPILE\fP and \fI\%JOB_POOL_LINK\fP\&. \fI\%Custom commands\fP and \fI\%custom targets\fP can specify pools using the option \fBJOB_POOL\fP\&. Using a pool that is not defined by \fBJOB_POOLS\fP causes an error by ninja at build time. .sp If not set, this property uses the value of the \fI\%CMAKE_JOB_POOLS\fP variable. .sp Build targets provided by CMake that are meant for individual interactive use, such as \fBinstall\fP, are placed in the \fBconsole\fP pool automatically. .SS PACKAGES_FOUND .sp List of packages which were found during the CMake run. .sp List of packages which were found during the CMake run. Whether a package has been found is determined using the _FOUND variables. .SS PACKAGES_NOT_FOUND .sp List of packages which were not found during the CMake run. .sp List of packages which were not found during the CMake run. Whether a package has been found is determined using the _FOUND variables. .SS PREDEFINED_TARGETS_FOLDER .sp Name of FOLDER for targets that are added automatically by CMake. .sp If not set, CMake uses \(dqCMakePredefinedTargets\(dq as a default value for this property. Targets such as INSTALL, PACKAGE and RUN_TESTS will be organized into this FOLDER. See also the documentation for the \fI\%FOLDER\fP target property. .SS REPORT_UNDEFINED_PROPERTIES .sp If set, report any undefined properties to this file. .sp If this property is set to a filename then when CMake runs it will report any properties or variables that were accessed but not defined into the filename specified in this property. .SS RULE_LAUNCH_COMPILE .sp Specify a launcher for compile rules. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 This property is intended for internal use by \fI\%ctest(1)\fP\&.

This is intended to allow launchers to intercept build problems with high granularity. Other generators ignore this property because their underlying build systems provide no hook to wrap individual commands with a launcher. .SS RULE_MESSAGES .sp Specify whether to report a message for each make rule. .sp This property specifies whether Makefile generators should add a progress message describing what each build rule does. If the property is not set the default is ON. Set the property to OFF to disable granular messages and report only as each target completes. This is intended to allow scripted builds to avoid the build time cost of detailed reports. If a \fI\%CMAKE_RULE_MESSAGES\fP cache entry exists its value initializes the value of this property. Non\-Makefile generators currently ignore this property. .SS TARGET_ARCHIVES_MAY_BE_SHARED_LIBS .sp Set if shared libraries may be named like archives. .sp On AIX shared libraries may be named \(dqlib.a\(dq. This property is set to true on such platforms. .SS TARGET_MESSAGES .sp New in version 3.4. .sp Specify whether to report the completion of each target. .sp This property specifies whether \fI\%Makefile Generators\fP should add a progress message describing that each target has been completed. If the property is not set the default is \fBON\fP\&. Set the property to \fBOFF\fP to disable target completion messages. .sp This option is intended to reduce build output when little or no work needs to be done to bring the build tree up to date. .sp If a \fBCMAKE_TARGET_MESSAGES\fP cache entry exists its value initializes the value of this property. .sp Non\-Makefile generators currently ignore this property. .sp See the counterpart property \fI\%RULE_MESSAGES\fP to disable everything except for target completion messages. .SS TARGET_SUPPORTS_SHARED_LIBS .sp Does the target platform support shared libraries. .sp TARGET_SUPPORTS_SHARED_LIBS is a boolean specifying whether the target platform supports shared libraries. Basically all current general general purpose OS do so, the exception are usually embedded systems with no or special OSs. .SS USE_FOLDERS .sp Controls whether to use the \fI\%FOLDER\fP target property to organize targets into folders. The value of \fBUSE_FOLDERS\fP at the end of the top level \fBCMakeLists.txt\fP file is what determines the behavior. .sp Changed in version 3.26: CMake treats this property as \fBON\fP by default. See policy \fI\%CMP0143\fP\&. .sp Not all CMake generators support recording folder details for targets. The \fI\%Xcode\fP and \fI\%Visual Studio\fP generators are examples of generators that do. Similarly, not all IDEs support presenting targets using folder hierarchies, even if the CMake generator used provides the necessary information. .SS XCODE_EMIT_EFFECTIVE_PLATFORM_NAME .sp New in version 3.8. .sp Control emission of \fBEFFECTIVE_PLATFORM_NAME\fP by the \fI\%Xcode\fP generator. .sp It is required for building the same target with multiple SDKs. A common use case is the parallel use of \fBiphoneos\fP and \fBiphonesimulator\fP SDKs. .sp Three different states possible that control when the \fI\%Xcode\fP generator emits the \fBEFFECTIVE_PLATFORM_NAME\fP variable: .INDENT 0.0 .IP \(bu 2 If set to \fBON\fP it will always be emitted .IP \(bu 2 If set to \fBOFF\fP it will never be emitted .IP \(bu 2 If unset (the default) it will only be emitted when the project was configured for an embedded Xcode SDK like iOS, tvOS, visionOS, watchOS or any of the simulators. .UNINDENT .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 When this behavior is enable for generated Xcode projects, the \fBEFFECTIVE_PLATFORM_NAME\fP variable will leak into \fI\%Generator expressions\fP like \fBTARGET_FILE\fP and will render those mostly unusable. .UNINDENT .UNINDENT .SH PROPERTIES ON DIRECTORIES .SS ADDITIONAL_CLEAN_FILES .sp New in version 3.15. .sp A \fI\%;\-list\fP of files or directories that will be removed as a part of the global \fBclean\fP target. It is useful for specifying generated files or directories that are used by multiple targets or by CMake itself, or that are generated in ways which cannot be captured as outputs or byproducts of custom commands. .sp If an additional clean file is specific to a single target only, then the \fI\%ADDITIONAL_CLEAN_FILES\fP target property would usually be a better choice than this directory property. .sp Relative paths are allowed and are interpreted relative to the current binary directory. .sp Contents of \fBADDITIONAL_CLEAN_FILES\fP may use \fI\%generator expressions\fP\&. .sp This property only works for the \fI\%Ninja\fP and the Makefile generators. It is ignored by other generators. .SS BINARY_DIR .sp New in version 3.7. .sp This read\-only directory property reports absolute path to the binary directory corresponding to the source on which it is read. .SS BUILDSYSTEM_TARGETS .sp New in version 3.7. .sp This read\-only directory property contains a \fI\%semicolon\-separated list\fP of buildsystem targets added in the directory by calls to the \fI\%add_library()\fP, \fI\%add_executable()\fP, and \fI\%add_custom_target()\fP commands. The list does not include any \fI\%Imported Targets\fP or \fI\%Alias Targets\fP, but does include \fI\%Interface Libraries\fP\&. Each entry in the list is the logical name of a target, suitable to pass to the \fI\%get_property()\fP command \fBTARGET\fP option. .sp See also the \fI\%IMPORTED_TARGETS\fP directory property. .SS CACHE_VARIABLES .sp List of cache variables available in the current directory. .sp This read\-only property specifies the list of CMake cache variables currently defined. It is intended for debugging purposes. .SS CLEAN_NO_CUSTOM .sp Set to true to tell \fI\%Makefile Generators\fP not to remove the outputs of custom commands for this directory during the \fBmake clean\fP operation. This is ignored on other generators because it is not possible to implement. .SS CMAKE_CONFIGURE_DEPENDS .sp Tell CMake about additional input files to the configuration process. If any named file is modified the build system will re\-run CMake to re\-configure the file and generate the build system again. .sp Specify files as a semicolon\-separated list of paths. Relative paths are interpreted as relative to the current source directory. .SS COMPILE_DEFINITIONS .sp Preprocessor definitions for compiling a directory\(aqs sources. .sp This property specifies the list of options given so far to the \fI\%add_compile_definitions()\fP (or \fI\%add_definitions()\fP) command. .sp The \fBCOMPILE_DEFINITIONS\fP property may be set to a semicolon\-separated list of preprocessor definitions using the syntax \fBVAR\fP or \fBVAR=value\fP\&. Function\-style definitions are not supported. CMake will automatically escape the value correctly for the native build system (note that CMake language syntax may require escapes to specify some values). .sp This property will be initialized in each directory by its value in the directory\(aqs parent. .sp CMake will automatically drop some definitions that are not supported by the native build tool. .sp New in version 3.26: Any leading \fB\-D\fP on an item will be removed. .sp Disclaimer: Most native build tools have poor support for escaping certain values. CMake has work\-arounds for many cases but some values may just not be possible to pass correctly. If a value does not seem to be escaped correctly, do not attempt to work\-around the problem by adding escape sequences to the value. Your work\-around may break in a future version of CMake that has improved escape support. Instead consider defining the macro in a (configured) header file. Then report the limitation. Known limitations include: .INDENT 0.0 .INDENT 3.5 .sp .EX # \- broken almost everywhere ; \- broken in VS IDE 7.0 and Borland Makefiles , \- broken in VS IDE % \- broken in some cases in NMake & | \- broken in some cases on MinGW ^ < > \e\(dq \- broken in most Make tools on Windows .EE .UNINDENT .UNINDENT .sp CMake does not reject these values outright because they do work in some cases. Use with caution. .sp Contents of \fBCOMPILE_DEFINITIONS\fP may use \(dqgenerator expressions\(dq with the syntax \fB$<...>\fP\&. See the \fI\%cmake\-generator\-expressions(7)\fP manual for available expressions. See the \fI\%cmake\-buildsystem(7)\fP manual for more on defining buildsystem properties. .sp The corresponding \fI\%COMPILE_DEFINITIONS_\fP property may be set to specify per\-configuration definitions. Generator expressions should be preferred instead of setting the alternative property. .SS COMPILE_OPTIONS .sp List of options to pass to the compiler. .sp This property holds a \fI\%semicolon\-separated list\fP of options given so far to the \fI\%add_compile_options()\fP command. .sp This property is used to initialize the \fI\%COMPILE_OPTIONS\fP target property when a target is created, which is used by the generators to set the options for the compiler. .sp Contents of \fBCOMPILE_OPTIONS\fP may use \(dqgenerator expressions\(dq with the syntax \fB$<...>\fP\&. See the \fI\%cmake\-generator\-expressions(7)\fP manual for available expressions. See the \fI\%cmake\-buildsystem(7)\fP manual for more on defining buildsystem properties. .SS DEFINITIONS .sp For CMake 2.4 compatibility only. Use \fI\%COMPILE_DEFINITIONS\fP instead. .sp This read\-only property specifies the list of flags given so far to the \fI\%add_definitions()\fP command. It is intended for debugging purposes. Use the \fI\%COMPILE_DEFINITIONS\fP directory property instead. .sp This built\-in read\-only property does not exist if policy \fI\%CMP0059\fP is set to \fBNEW\fP\&. .SS EXCLUDE_FROM_ALL .sp Set this directory property to a true value on a subdirectory to exclude its targets from the \(dqall\(dq target of its ancestors. If excluded, running e.g. \fBmake\fP in the parent directory will not build targets the subdirectory by default. This does not affect the \(dqall\(dq target of the subdirectory itself. Running e.g. \fBmake\fP inside the subdirectory will still build its targets. .sp If the \fI\%EXCLUDE_FROM_ALL\fP target property is set on a target then its value determines whether the target is included in the \(dqall\(dq target of this directory and its ancestors. .SS IMPLICIT_DEPENDS_INCLUDE_TRANSFORM .sp Specify \fB#include\fP line transforms for dependencies in a directory. .sp This property specifies rules to transform macro\-like \fB#include\fP lines during implicit dependency scanning of C and C++ source files. The list of rules must be semicolon\-separated with each entry of the form \fBA_MACRO(%)=value\-with\-%\fP (the \fB%\fP must be literal). During dependency scanning occurrences of \fBA_MACRO(...)\fP on \fB#include\fP lines will be replaced by the value given with the macro argument substituted for \fB%\fP\&. For example, the entry .INDENT 0.0 .INDENT 3.5 .sp .EX MYDIR(%)= .EE .UNINDENT .UNINDENT .sp will convert lines of the form .INDENT 0.0 .INDENT 3.5 .sp .EX #include MYDIR(myheader.h) .EE .UNINDENT .UNINDENT .sp to .INDENT 0.0 .INDENT 3.5 .sp .EX #include .EE .UNINDENT .UNINDENT .sp allowing the dependency to be followed. .sp This property applies to sources in all targets within a directory. The property value is initialized in each directory by its value in the directory\(aqs parent. .SS IMPORTED_TARGETS .sp New in version 3.21. .sp This read\-only directory property contains a \fI\%semicolon\-separated list\fP of \fI\%Imported Targets\fP added in the directory by calls to the \fI\%add_library()\fP and \fI\%add_executable()\fP commands. Each entry in the list is the logical name of a target, suitable to pass to the \fI\%get_property()\fP command \fBTARGET\fP option when called in the same directory. .sp See also the \fI\%BUILDSYSTEM_TARGETS\fP directory property. .SS INCLUDE_DIRECTORIES .sp List of preprocessor include file search directories. .sp This property specifies the list of directories given so far to the \fI\%include_directories()\fP command. .sp This property is used to populate the \fI\%INCLUDE_DIRECTORIES\fP target property, which is used by the generators to set the include directories for the compiler. .sp In addition to accepting values from that command, values may be set directly on any directory using the \fI\%set_property()\fP command, and can be set on the current directory using the \fI\%set_directory_properties()\fP command. A directory gets its initial value from its parent directory if it has one. The initial value of the \fI\%INCLUDE_DIRECTORIES\fP target property comes from the value of this property. Both directory and target property values are adjusted by calls to the \fI\%include_directories()\fP command. Calls to \fI\%set_property()\fP or \fI\%set_directory_properties()\fP, however, will update the directory property value without updating target property values. Therefore direct property updates must be made before calls to \fI\%add_executable()\fP or \fI\%add_library()\fP for targets they are meant to affect. .sp The target property values are used by the generators to set the include paths for the compiler. .sp Contents of \fBINCLUDE_DIRECTORIES\fP may use \(dqgenerator expressions\(dq with the syntax \fB$<...>\fP\&. See the \fI\%cmake\-generator\-expressions(7)\fP manual for available expressions. See the \fI\%cmake\-buildsystem(7)\fP manual for more on defining buildsystem properties. .SS INCLUDE_REGULAR_EXPRESSION .sp Include file scanning regular expression. .sp This property specifies the regular expression used during dependency scanning to match include files that should be followed. See the \fI\%include_regular_expression()\fP command for a high\-level interface to set this property. .SS LABELS .sp New in version 3.10. .sp Specify a list of text labels associated with a directory and all of its subdirectories. This is equivalent to setting the \fI\%LABELS\fP target property and the \fI\%LABELS\fP test property on all targets and tests in the current directory and subdirectories. Note: Launchers must enabled to propagate labels to targets. .sp The \fI\%CMAKE_DIRECTORY_LABELS\fP variable can be used to initialize this property. .sp The list is reported in dashboard submissions. .SS LINK_DIRECTORIES .sp List of linker search directories. .sp This property holds a \fI\%semicolon\-separated list\fP of directories and is typically populated using the \fI\%link_directories()\fP command. It gets its initial value from its parent directory, if it has one. .sp The directory property is used to initialize the \fI\%LINK_DIRECTORIES\fP target property when a target is created. That target property is used by the generators to set the library search directories for the linker. .sp Contents of \fBLINK_DIRECTORIES\fP may use \(dqgenerator expressions\(dq with the syntax \fB$<...>\fP\&. See the \fI\%cmake\-generator\-expressions(7)\fP manual for available expressions. See the \fI\%cmake\-buildsystem(7)\fP manual for more on defining buildsystem properties. .SS LINK_OPTIONS .sp New in version 3.13. .sp List of options to use for the link step of shared library, module and executable targets as well as the device link step. .sp This property holds a \fI\%semicolon\-separated list\fP of options given so far to the \fI\%add_link_options()\fP command. .sp This property is used to initialize the \fI\%LINK_OPTIONS\fP target property when a target is created, which is used by the generators to set the options for the compiler. .sp Contents of \fBLINK_OPTIONS\fP may use \(dqgenerator expressions\(dq with the syntax \fB$<...>\fP\&. See the \fI\%cmake\-generator\-expressions(7)\fP manual for available expressions. See the \fI\%cmake\-buildsystem(7)\fP manual for more on defining buildsystem properties. .SS LISTFILE_STACK .sp The current stack of listfiles being processed. .sp This property is mainly useful when trying to debug errors in your CMake scripts. It returns a list of what list files are currently being processed, in order. So if one listfile does an \fI\%include()\fP command then that is effectively pushing the included listfile onto the stack. .SS MACROS .sp List of macro commands available in the current directory. .sp This read\-only property specifies the list of CMake macros currently defined. It is intended for debugging purposes. See the \fI\%macro()\fP command. .SS PARENT_DIRECTORY .sp Source directory that added current subdirectory. .sp This read\-only property specifies the source directory that added the current source directory as a subdirectory of the build. In the top\-level directory the value is the empty\-string. .SS RULE_LAUNCH_COMPILE .sp Specify a launcher for compile rules. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 This property is intended for internal use by \fI\%ctest(1)\fP\&. Projects and developers should use the \fI\%_COMPILER_LAUNCHER\fP target properties or the associated \fI\%CMAKE__COMPILER_LAUNCHER\fP variables instead. .UNINDENT .UNINDENT .sp See the \fI\%global property\fP of the same name for details. This overrides the global property for a directory. .SS RULE_LAUNCH_CUSTOM .sp Specify a launcher for custom rules. .sp See the global property of the same name for details. This overrides the global property for a directory. .SS RULE_LAUNCH_LINK .sp Specify a launcher for link rules. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 This property is intended for internal use by \fI\%ctest(1)\fP\&. Projects and developers should use the \fI\%_LINKER_LAUNCHER\fP target properties or the associated \fI\%CMAKE__LINKER_LAUNCHER\fP variables instead. .UNINDENT .UNINDENT .sp See the \fI\%global property\fP of the same name for details. This overrides the global property for a directory. .SS SOURCE_DIR .sp New in version 3.7. .sp This read\-only directory property reports absolute path to the source directory on which it is read. .SS SUBDIRECTORIES .sp New in version 3.7. .sp This read\-only directory property contains a \fI\%semicolon\-separated list\fP of subdirectories processed so far by the \fI\%add_subdirectory()\fP or \fI\%subdirs()\fP commands. Each entry is the absolute path to the source directory (containing the \fBCMakeLists.txt\fP file). This is suitable to pass to the \fI\%get_property()\fP command \fBDIRECTORY\fP option. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 The \fI\%subdirs()\fP command does not process its arguments until after the calling directory is fully processed. Therefore looking up this property in the current directory will not see them. .UNINDENT .UNINDENT .SS SYSTEM .sp New in version 3.25. .sp This directory property is used to initialize the \fI\%SYSTEM\fP target property for non\-imported targets created in that directory. It is set to true by \fI\%add_subdirectory()\fP and \fI\%FetchContent_Declare()\fP when the \fBSYSTEM\fP option is given as an argument to those commands. .SS TESTS .sp New in version 3.12. .sp List of tests. .sp This read\-only property holds a \fI\%semicolon\-separated list\fP of tests defined so far, in the current directory, by the \fI\%add_test()\fP command. .SS TEST_INCLUDE_FILES .sp New in version 3.10. .sp A list of cmake files that will be included when ctest is run. .sp If you specify \fBTEST_INCLUDE_FILES\fP, those files will be included and processed when ctest is run on the directory. .SS VARIABLES .sp List of variables defined in the current directory. .sp This read\-only property specifies the list of CMake variables currently defined. It is intended for debugging purposes. .SS VS_GLOBAL_SECTION_POST_
.sp Specify a postSolution global section in Visual Studio. .sp Setting a property like this generates an entry of the following form in the solution file: .INDENT 0.0 .INDENT 3.5 .sp .EX GlobalSection(
) = postSolution EndGlobalSection .EE .UNINDENT .UNINDENT .sp The property must be set to a semicolon\-separated list of \fBkey=value\fP pairs. Each such pair will be transformed into an entry in the solution global section. Whitespace around key and value is ignored. List elements which do not contain an equal sign are skipped. .sp This property only works for Visual Studio 9 and above; it is ignored on other generators. The property only applies when set on a directory whose \fBCMakeLists.txt\fP contains a \fI\%project()\fP command. .sp Note that CMake generates postSolution sections \fBExtensibilityGlobals\fP and \fBExtensibilityAddIns\fP by default. If you set the corresponding property, it will override the default section. For example, setting \fBVS_GLOBAL_SECTION_POST_ExtensibilityGlobals\fP will override the default contents of the \fBExtensibilityGlobals\fP section, while keeping ExtensibilityAddIns on its default. However, CMake will always add a \fBSolutionGuid\fP to the \fBExtensibilityGlobals\fP section if it is not specified explicitly. .SS VS_GLOBAL_SECTION_PRE_
.sp Specify a preSolution global section in Visual Studio. .sp Setting a property like this generates an entry of the following form in the solution file: .INDENT 0.0 .INDENT 3.5 .sp .EX GlobalSection(
) = preSolution EndGlobalSection .EE .UNINDENT .UNINDENT .sp The property must be set to a semicolon\-separated list of \fBkey=value\fP pairs. Each such pair will be transformed into an entry in the solution global section. Whitespace around key and value is ignored. List elements which do not contain an equal sign are skipped. .sp This property only works for Visual Studio 9 and above; it is ignored on other generators. The property only applies when set on a directory whose \fBCMakeLists.txt\fP contains a \fI\%project()\fP command. .SS VS_STARTUP_PROJECT .sp New in version 3.6. .sp Specify the default startup project in a Visual Studio solution. .sp The \fI\%Visual Studio Generators\fP create a \fB\&.sln\fP file for each directory whose \fBCMakeLists.txt\fP file calls the \fI\%project()\fP command. Set this property in the same directory as a \fI\%project()\fP command call (e.g. in the top\-level \fBCMakeLists.txt\fP file) to specify the default startup project for the corresponding solution file. .sp The property must be set to the name of an existing target. This will cause that project to be listed first in the generated solution file causing Visual Studio to make it the startup project if the solution has never been opened before. .sp If this property is not specified, then the \fBALL_BUILD\fP project will be the default. .SH PROPERTIES ON TARGETS .SS ADDITIONAL_CLEAN_FILES .sp New in version 3.15. .sp A \fI\%;\-list\fP of files or directories that will be removed as a part of the global \fBclean\fP target. It can be used to specify files and directories that are generated as part of building the target or that are directly associated with the target in some way (e.g. created as a result of running the target). .sp For custom targets, if such files can be captured as outputs or byproducts instead, then that should be preferred over adding them to this property. If an additional clean file is used by multiple targets or isn\(aqt target\-specific, then the \fI\%ADDITIONAL_CLEAN_FILES\fP directory property may be the more appropriate property to use. .sp Relative paths are allowed and are interpreted relative to the current binary directory. .sp Contents of \fBADDITIONAL_CLEAN_FILES\fP may use \fI\%generator expressions\fP\&. .sp This property only works for the \fI\%Ninja\fP and the Makefile generators. It is ignored by other generators. .SS AIX_EXPORT_ALL_SYMBOLS .sp New in version 3.17. .sp On AIX, CMake automatically exports all symbols from shared libraries, and from executables with the \fI\%ENABLE_EXPORTS\fP target property set. Explicitly disable this boolean property to suppress the behavior and export no symbols by default. In this case it is expected that the project will use other means to export some symbols. .sp This property is initialized by the value of the \fI\%CMAKE_AIX_EXPORT_ALL_SYMBOLS\fP variable if it is set when a target is created. .SS ALIAS_GLOBAL .sp New in version 3.18. .sp Read\-only property indicating of whether an \fI\%ALIAS target\fP is globally visible. .sp The boolean value of this property is \fBTRUE\fP for aliases to \fI\%IMPORTED targets\fP created with the \fBGLOBAL\fP options to \fI\%add_executable()\fP or \fI\%add_library()\fP, \fBFALSE\fP otherwise. It is undefined for targets built within the project. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 Promoting an \fI\%IMPORTED target\fP from \fBLOCAL\fP to \fBGLOBAL\fP scope by changing the value or \fI\%IMPORTED_GLOBAL\fP target property do not change the scope of local aliases. .UNINDENT .UNINDENT .SS ALIASED_TARGET .sp Name of target aliased by this target. .sp If this is an \fI\%Alias Target\fP, this property contains the name of the target aliased. .SS ANDROID_ANT_ADDITIONAL_OPTIONS .sp New in version 3.4. .sp Set the additional options for Android Ant build system. This is a string value containing all command line options for the Ant build. This property is initialized by the value of the \fI\%CMAKE_ANDROID_ANT_ADDITIONAL_OPTIONS\fP variable if it is set when a target is created. .SS ANDROID_API .sp New in version 3.1. .sp When \fI\%Cross Compiling for Android with NVIDIA Nsight Tegra Visual Studio Edition\fP, this property sets the Android target API version (e.g. \fB15\fP). The version number must be a positive decimal integer. This property is initialized by the value of the \fI\%CMAKE_ANDROID_API\fP variable if it is set when a target is created. .SS ANDROID_API_MIN .sp New in version 3.2. .sp Set the Android MIN API version (e.g. \fB9\fP). The version number must be a positive decimal integer. This property is initialized by the value of the \fI\%CMAKE_ANDROID_API_MIN\fP variable if it is set when a target is created. Native code builds using this API version. .SS ANDROID_ARCH .sp New in version 3.4. .sp When \fI\%Cross Compiling for Android with NVIDIA Nsight Tegra Visual Studio Edition\fP, this property sets the Android target architecture. .sp This is a string property that could be set to the one of the following values: .INDENT 0.0 .IP \(bu 2 \fBarmv7\-a\fP: \(dqARMv7\-A (armv7\-a)\(dq .IP \(bu 2 \fBarmv7\-a\-hard\fP: \(dqARMv7\-A, hard\-float ABI (armv7\-a)\(dq .IP \(bu 2 \fBarm64\-v8a\fP: \(dqARMv8\-A, 64bit (arm64\-v8a)\(dq .IP \(bu 2 \fBx86\fP: \(dqx86 (x86)\(dq .IP \(bu 2 \fBx86_64\fP: \(dqx86_64 (x86_64)\(dq .UNINDENT .sp This property is initialized by the value of the \fI\%CMAKE_ANDROID_ARCH\fP variable if it is set when a target is created. .SS ANDROID_ASSETS_DIRECTORIES .sp New in version 3.4. .sp Set the Android assets directories to copy into the main assets folder before build. This a string property that contains the directory paths separated by semicolon. This property is initialized by the value of the \fI\%CMAKE_ANDROID_ASSETS_DIRECTORIES\fP variable if it is set when a target is created. .SS ANDROID_GUI .sp New in version 3.1. .sp When \fI\%Cross Compiling for Android with NVIDIA Nsight Tegra Visual Studio Edition\fP, this property specifies whether to build an executable as an application package on Android. .sp When this property is set to true the executable when built for Android will be created as an application package. This property is initialized by the value of the \fI\%CMAKE_ANDROID_GUI\fP variable if it is set when a target is created. .sp Add the \fBAndroidManifest.xml\fP source file explicitly to the target \fI\%add_executable()\fP command invocation to specify the root directory of the application package source. .SS ANDROID_JAR_DEPENDENCIES .sp New in version 3.4. .sp Set the Android property that specifies JAR dependencies. This is a string value property. This property is initialized by the value of the \fI\%CMAKE_ANDROID_JAR_DEPENDENCIES\fP variable if it is set when a target is created. .SS ANDROID_JAR_DIRECTORIES .sp New in version 3.4. .sp Set the Android property that specifies directories to search for the JAR libraries. .sp This a string property that contains the directory paths separated by semicolons. This property is initialized by the value of the \fI\%CMAKE_ANDROID_JAR_DIRECTORIES\fP variable if it is set when a target is created. .sp Contents of \fBANDROID_JAR_DIRECTORIES\fP may use \(dqgenerator expressions\(dq with the syntax \fB$<...>\fP\&. See the \fI\%cmake\-generator\-expressions(7)\fP manual for available expressions. .SS ANDROID_JAVA_SOURCE_DIR .sp New in version 3.4. .sp Set the Android property that defines the Java source code root directories. This a string property that contains the directory paths separated by semicolon. This property is initialized by the value of the \fI\%CMAKE_ANDROID_JAVA_SOURCE_DIR\fP variable if it is set when a target is created. .SS ANDROID_NATIVE_LIB_DEPENDENCIES .sp New in version 3.4. .sp Set the Android property that specifies the .so dependencies. This is a string property. .sp This property is initialized by the value of the \fI\%CMAKE_ANDROID_NATIVE_LIB_DEPENDENCIES\fP variable if it is set when a target is created. .sp Contents of \fBANDROID_NATIVE_LIB_DEPENDENCIES\fP may use \(dqgenerator expressions\(dq with the syntax \fB$<...>\fP\&. See the \fI\%cmake\-generator\-expressions(7)\fP manual for available expressions. .SS ANDROID_NATIVE_LIB_DIRECTORIES .sp New in version 3.4. .sp Set the Android property that specifies directories to search for the \fB\&.so\fP libraries. .sp This a string property that contains the directory paths separated by semicolons. .sp This property is initialized by the value of the \fI\%CMAKE_ANDROID_NATIVE_LIB_DIRECTORIES\fP variable if it is set when a target is created. .sp Contents of \fBANDROID_NATIVE_LIB_DIRECTORIES\fP may use \(dqgenerator expressions\(dq with the syntax \fB$<...>\fP\&. See the \fI\%cmake\-generator\-expressions(7)\fP manual for available expressions. .SS ANDROID_PROCESS_MAX .sp New in version 3.4. .sp Set the Android property that defines the maximum number of a parallel Android NDK compiler processes (e.g. \fB4\fP). This property is initialized by the value of the \fI\%CMAKE_ANDROID_PROCESS_MAX\fP variable if it is set when a target is created. .SS ANDROID_PROGUARD .sp New in version 3.4. .sp When this property is set to true that enables the ProGuard tool to shrink, optimize, and obfuscate the code by removing unused code and renaming classes, fields, and methods with semantically obscure names. This property is initialized by the value of the \fI\%CMAKE_ANDROID_PROGUARD\fP variable if it is set when a target is created. .SS ANDROID_PROGUARD_CONFIG_PATH .sp New in version 3.4. .sp Set the Android property that specifies the location of the ProGuard config file. Leave empty to use the default one. This a string property that contains the path to ProGuard config file. This property is initialized by the value of the \fI\%CMAKE_ANDROID_PROGUARD_CONFIG_PATH\fP variable if it is set when a target is created. .SS ANDROID_SECURE_PROPS_PATH .sp New in version 3.4. .sp Set the Android property that states the location of the secure properties file. This is a string property that contains the file path.

For example: \fBnetcoreapp2.1\fP\&. .sp This property is only evaluated for \fI\%Visual Studio Generators\fP VS 2010 and above. .sp Can be initialized for all targets using the variable \fI\%CMAKE_DOTNET_TARGET_FRAMEWORK\fP\&. .SS DOTNET_TARGET_FRAMEWORK_VERSION .sp New in version 3.12. .sp Specify the .NET target framework version. .sp Used to specify the .NET target framework version for C++/CLI and C#. For example: \fBv4.5\fP\&. .sp This property is only evaluated for \fI\%Visual Studio Generators\fP VS 2010 and above. .sp To initialize this variable for all targets set \fI\%CMAKE_DOTNET_TARGET_FRAMEWORK\fP or \fI\%CMAKE_DOTNET_TARGET_FRAMEWORK_VERSION\fP\&. If both are set, the latter is ignored. .SS EchoString .sp A message to be displayed when the target is built. .sp A message to display on some generators (such as \fI\%Makefile Generators\fP) when the target is built. .SS ENABLE_EXPORTS .sp Specify whether an executable or a shared library exports symbols. .sp Normally an executable does not export any symbols because it is the final program. It is possible for an executable to export symbols to be used by loadable modules. When this property is set to true CMake will allow other targets to \(dqlink\(dq to the executable with the \fI\%target_link_libraries()\fP command. On all platforms a target\-level dependency on the executable is created for targets that link to it. Handling of the executable on the link lines of the loadable modules varies by platform: .INDENT 0.0 .IP \(bu 2 On Windows\-based systems (including Cygwin) an \(dqimport library\(dq is created along with the executable to list the exported symbols. Loadable modules link to the import library to get the symbols. .IP \(bu 2 On macOS, loadable modules link to the executable itself using the \fB\-bundle_loader\fP flag. .IP \(bu 2 On AIX, a linker \(dqimport file\(dq is created along with the executable to list the exported symbols for import when linking other targets. Loadable modules link to the import file to get the symbols. .IP \(bu 2 On other platforms, loadable modules are simply linked without referencing the executable since the dynamic loader will automatically bind symbols when the module is loaded. .UNINDENT .sp This property is initialized by the value of the \fI\%CMAKE_EXECUTABLE_ENABLE_EXPORTS\fP variable, if it is set when an executable target is created. If \fI\%CMAKE_EXECUTABLE_ENABLE_EXPORTS\fP is not set, the \fI\%CMAKE_ENABLE_EXPORTS\fP variable is used to initialize the property instead for backward compatibility reasons. See below for alternative initialization behavior for shared library targets. .sp New in version 3.27: To link with a shared library on macOS, or to a shared framework on any Apple platform, a linker import file can be used instead of the actual shared library. These linker import files are also known as text\-based stubs, and they have a \fB\&.tbd\fP file extension. .sp The generation of these linker import files, as well as their consumption, is controlled by this property. When this property is set to true on a shared library target, CMake will generate a \fB\&.tbd\fP file for the library. Other targets that link to the shared library target will then use this \fB\&.tbd\fP file when linking rather than linking to the shared library binary. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 For backward compatibility reasons, this property will be ignored if the \fI\%XCODE_ATTRIBUTE_GENERATE_TEXT_BASED_STUBS\fP target property or the \fI\%CMAKE_XCODE_ATTRIBUTE_GENERATE_TEXT_BASED_STUBS\fP variable is set to false. .UNINDENT .UNINDENT .sp For shared library targets, this property is initialized by the value of the \fI\%CMAKE_SHARED_LIBRARY_ENABLE_EXPORTS\fP variable, if it is set when the target is created. .SS EXCLUDE_FROM_ALL .sp Set this target property to a true (or false) value to exclude (or include) the target from the \(dqall\(dq target of the containing directory and its ancestors. If excluded, running e.g. \fBmake\fP in the containing directory or its ancestors will not build the target by default. .sp If this target property is not set then the target will be included in the \(dqall\(dq target of the containing directory. Furthermore, it will be included in the \(dqall\(dq target of its ancestor directories unless the \fI\%EXCLUDE_FROM_ALL\fP directory property is set. .sp With \fBEXCLUDE_FROM_ALL\fP set to false or not set at all, the target will be brought up to date as part of doing a \fBmake install\fP or its equivalent for the CMake generator being used. .sp If a target has \fBEXCLUDE_FROM_ALL\fP set to true, it may still be listed in an \fI\%install(TARGETS)\fP command, but the user is responsible for ensuring that the target\(aqs build artifacts are not missing or outdated when an install is performed. .sp This property may use \(dqgenerator expressions\(dq with the syntax \fB$<...>\fP\&. See the \fI\%cmake\-generator\-expressions(7)\fP manual for available expressions. .sp Only the \(dqNinja Multi\-Config\(dq generator supports a property value that varies by configuration. For all other generators the value of this property must be the same for all configurations. .SS EXCLUDE_FROM_DEFAULT_BUILD .sp Exclude target from \fBBuild Solution\fP\&. .sp This property is only used by Visual Studio generators. When set to \fBTRUE\fP, the target will not be built when you press \fBBuild Solution\fP\&. .SS EXCLUDE_FROM_DEFAULT_BUILD_ .sp Per\-configuration version of target exclusion from \fBBuild Solution\fP\&. .sp This is the configuration\-specific version of \fI\%EXCLUDE_FROM_DEFAULT_BUILD\fP\&. If the generic \fI\%EXCLUDE_FROM_DEFAULT_BUILD\fP is also set on a target, \fBEXCLUDE_FROM_DEFAULT_BUILD_\fP takes precedence in configurations for which it has a value. .SS EXPORT_COMPILE_COMMANDS .sp New in version 3.20. .sp Enable/Disable output of compile commands during generation for a target. .sp This property is initialized by the value of the variable \fI\%CMAKE_EXPORT_COMPILE_COMMANDS\fP if it is set when a target is created. .SS EXPORT_NAME .sp Exported name for target files. .sp This sets the name for the \fBIMPORTED\fP target generated by the \fI\%install(EXPORT)\fP and \fI\%export()\fP commands. If not set, the logical target name is used by default. .SS EXPORT_NO_SYSTEM .sp New in version 3.25. .sp This property affects the behavior of the \fI\%install(EXPORT)\fP and \fI\%export()\fP commands when they install or export the target respectively. When \fBEXPORT_NO_SYSTEM\fP is set to true, those commands generate an imported target with \fI\%SYSTEM\fP property set to false. .sp See the \fI\%NO_SYSTEM_FROM_IMPORTED\fP target property to set this behavior on the target \fIconsuming\fP the include directories rather than the one \fIproviding\fP them. .SS EXPORT_PROPERTIES .sp New in version 3.12. .sp List additional properties to export for a target. .sp This property contains a list of property names that should be exported by the \fI\%install(EXPORT)\fP and \fI\%export()\fP commands. By default only a limited number of properties are exported. This property can be used to additionally export other properties as well. .sp Properties starting with \fBINTERFACE_\fP or \fBIMPORTED_\fP are not allowed as they are reserved for internal CMake use. .sp Properties containing generator expressions are also not allowed. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 Since CMake 3.19, \fI\%Interface Libraries\fP may have arbitrary target properties. If a project exports an interface library with custom properties, the resulting package may not work with dependents configured by older versions of CMake that reject the custom properties. .UNINDENT .UNINDENT .SS FOLDER .sp For IDEs that present targets using a folder hierarchy, this property specifies the name of the folder to place the target under. To nest folders, use \fBFOLDER\fP values such as \fBGUI/Dialogs\fP with \fB/\fP characters separating folder levels. Targets with no \fBFOLDER\fP property will appear as top level entities. Targets with the same \fBFOLDER\fP property value will appear in the same folder as siblings. .sp Only some CMake generators honor the \fBFOLDER\fP property (e.g. \fI\%Xcode\fP or any of the \fI\%Visual Studio\fP generators). Those generators that don\(aqt will simply ignore it. .sp This property is initialized by the value of the variable \fI\%CMAKE_FOLDER\fP if it is set when a target is created. .sp The global property \fI\%USE_FOLDERS\fP must be set to true, otherwise the \fBFOLDER\fP property is ignored. .SS Fortran_BUILDING_INSTRINSIC_MODULES .sp New in version 3.22. .sp Instructs the CMake Fortran preprocessor that the target is building Fortran intrinsics for building a Fortran compiler. .sp This property is off by default and should be turned only on projects that build a Fortran compiler. It should not be turned on for projects that use a Fortran compiler. .sp Turning this property on will correctly add dependencies for building Fortran intrinsic modules whereas turning the property off will ignore Fortran intrinsic modules in the dependency graph as they are supplied by the compiler itself. .SS Fortran_FORMAT .sp Set to \fBFIXED\fP or \fBFREE\fP to indicate the Fortran source layout. .sp This property tells CMake whether the Fortran source files in a target use fixed\-format or free\-format. CMake will pass the corresponding format flag to the compiler. Use the source\-specific \fBFortran_FORMAT\fP property to change the format of a specific source file. If the variable \fI\%CMAKE_Fortran_FORMAT\fP is set when a target is created its value is used to initialize this property. .SS Fortran_MODULE_DIRECTORY .sp Specify output directory for Fortran modules provided by the target. .sp If the target contains Fortran source files that provide modules and the compiler supports a module output directory this specifies the directory in which the modules will be placed. When this property is not set the modules will be placed in the build directory corresponding to the target\(aqs source directory. If the variable \fI\%CMAKE_Fortran_MODULE_DIRECTORY\fP is set when a target is created its value is used to initialize this property. .sp When using one of the \fI\%Visual Studio Generators\fP with the Intel Fortran plugin installed in Visual Studio, a subdirectory named after the configuration will be appended to the path where modules are created. For example, if \fBFortran_MODULE_DIRECTORY\fP is set to \fBC:/some/path\fP, modules will end up in \fBC:/some/path/Debug\fP (or \fBC:/some/path/Release\fP etc.) when an Intel Fortran \fB\&.vfproj\fP file is generated, and in \fBC:/some/path\fP when any other generator is used. .sp Note that some compilers will automatically search the module output directory for modules USEd during compilation but others will not. If your sources USE modules their location must be specified by \fI\%INCLUDE_DIRECTORIES\fP regardless of this property. .SS Fortran_PREPROCESS .sp New in version 3.18. .sp Control whether the Fortran source file should be unconditionally preprocessed. .sp If unset or empty, rely on the compiler to determine whether the file should be preprocessed. If explicitly set to \fBOFF\fP then the file does not need to be preprocessed. If explicitly set to \fBON\fP, then the file does need to be preprocessed as part of the compilation step. .sp When using the \fI\%Ninja\fP generator, all source files are first preprocessed in order to generate module dependency information. Setting this property to \fBOFF\fP will make \fBNinja\fP skip this step. .sp Use the source\-specific \fI\%Fortran_PREPROCESS\fP property if a single file needs to be preprocessed. If the variable \fI\%CMAKE_Fortran_PREPROCESS\fP is set when a target is created its value is used to initialize this property. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 For some compilers, \fBNAG\fP, \fBPGI\fP and \fBSolaris Studio\fP, setting this to \fBOFF\fP will have no effect. .UNINDENT .UNINDENT .SS FRAMEWORK .sp Build \fBSHARED\fP or \fBSTATIC\fP library as Framework Bundle on the macOS and iOS. .sp If such a library target has this property set to \fBTRUE\fP it will be built as a framework when built on the macOS and iOS. It will have the directory structure required for a framework and will be suitable to be used with the \fB\-framework\fP option. This property is initialized by the value of the \fI\%CMAKE_FRAMEWORK\fP variable if it is set when a target is created. .sp To customize \fBInfo.plist\fP file in the framework, use \fI\%MACOSX_FRAMEWORK_INFO_PLIST\fP target property. .sp For macOS see also the \fI\%FRAMEWORK_VERSION\fP target property. .sp Example of creation \fBdynamicFramework\fP: .INDENT 0.0 .INDENT 3.5 .sp .EX add_library(dynamicFramework SHARED dynamicFramework.c dynamicFramework.h ) set_target_properties(dynamicFramework PROPERTIES FRAMEWORK TRUE FRAMEWORK_VERSION C MACOSX_FRAMEWORK_IDENTIFIER com.cmake.dynamicFramework MACOSX_FRAMEWORK_INFO_PLIST Info.plist # \(dqcurrent version\(dq in semantic format in Mach\-O binary file VERSION 16.4.0 # \(dqcompatibility version\(dq in semantic format in Mach\-O binary file SOVERSION 1.0.0 PUBLIC_HEADER dynamicFramework.h XCODE_ATTRIBUTE_CODE_SIGN_IDENTITY \(dqiPhone Developer\(dq ) .EE .UNINDENT .UNINDENT .SS FRAMEWORK_MULTI_CONFIG_POSTFIX_ .sp New in version 3.18. .sp Postfix to append to the framework file name for configuration \fB\fP, when using a multi\-config generator (like Xcode and Ninja Multi\-Config). .sp When building with configuration \fB\fP the value of this property is appended to the framework file name built on disk. .sp For example, given a framework called \fBmy_fw\fP, a value of \fB_debug\fP for the \fBFRAMEWORK_MULTI_CONFIG_POSTFIX_DEBUG\fP property, and \fBDebug;Release\fP in \fI\%CMAKE_CONFIGURATION_TYPES\fP, the following relevant files would be created for the \fBDebug\fP and \fBRelease\fP configurations: .INDENT 0.0 .IP \(bu 2 \fBRelease/my_fw.framework/my_fw\fP .IP \(bu 2 \fBRelease/my_fw.framework/Versions/A/my_fw\fP .IP \(bu 2 \fBDebug/my_fw.framework/my_fw_debug\fP .IP \(bu 2 \fBDebug/my_fw.framework/Versions/A/my_fw_debug\fP .UNINDENT .sp For framework targets, this property is initialized by the value of the \fI\%CMAKE_FRAMEWORK_MULTI_CONFIG_POSTFIX_\fP variable if it is set when a target is created. .sp This property is ignored for non\-framework targets, and when using single config generators. .SS FRAMEWORK_VERSION .sp New in version 3.4. .sp Version of a framework created using the \fI\%FRAMEWORK\fP target property (e.g. \fBA\fP). .sp This property only affects macOS, as iOS doesn\(aqt have versioned directory structure. .SS GENERATOR_FILE_NAME .sp Generator\(aqs file for this target. .sp An internal property used by some generators to record the name of the project or dsp file associated with this target.

Both import libraries will be installed by \fI\%install(TARGETS)\fP and exported by \fI\%install(EXPORT)\fP and \fI\%export()\fP to be linked by applications with either GNU\- or MS\-compatible tools. .sp If the variable \fBCMAKE_GNUtoMS\fP is set when a target is created its value is used to initialize this property. The variable must be set prior to the first command that enables a language such as \fI\%project()\fP or \fI\%enable_language()\fP\&. CMake provides the variable as an option to the user automatically when configuring on Windows with GNU tools. .SS HAS_CXX .sp Link the target using the C++ linker tool (obsolete). .sp This is equivalent to setting the \fI\%LINKER_LANGUAGE\fP property to \fBCXX\fP\&. .SS HEADER_DIRS .sp New in version 3.23. .sp Semicolon\-separated list of base directories of the target\(aqs default header set (i.e. the file set with name and type \fBHEADERS\fP).

Architecture names are interpreted based on \fI\%CMAKE_HIP_PLATFORM\fP\&. .sp A non\-empty false value (e.g. \fBOFF\fP) disables adding architectures. This is intended to support packagers and rare cases where full control over the passed flags is required. .sp This property is initialized by the value of the \fI\%CMAKE_HIP_ARCHITECTURES\fP variable if it is set when a target is created. .sp The HIP compilation model has two modes: whole and separable. Whole compilation generates device code at compile time. Separable compilation generates device code at link time.

For some compilers, this results in adding a flag such as \fB\-std=gnu++11\fP instead of \fB\-std=c++11\fP to the compile line. This property is \fBON\fP by default. The basic HIP/C++ standard level is controlled by the \fI\%HIP_STANDARD\fP target property. .sp See the \fI\%cmake\-compile\-features(7)\fP manual for information on compile features and a list of supported compilers. .sp This property is initialized by the value of the \fI\%CMAKE_HIP_EXTENSIONS\fP variable if set when a target is created and otherwise by the value of \fI\%CMAKE_HIP_EXTENSIONS_DEFAULT\fP (see \fI\%CMP0128\fP). .SS HIP_STANDARD .sp New in version 3.21. .sp The HIP/C++ standard requested to build this target. .sp Supported values are: .INDENT 0.0 .TP .B \fB98\fP HIP C++98 .TP .B \fB11\fP HIP C++11 .TP .B \fB14\fP HIP C++14 .TP .B \fB17\fP HIP C++17 .TP .B \fB20\fP HIP C++20 .TP .B \fB23\fP HIP C++23 .TP .B \fB26\fP New in version 3.25. .sp HIP C++26.

This is controlled by the \fI\%CMAKE_OSX_ARCHITECTURES\fP variable. For all but the \fI\%Xcode\fP generator, CMake invokes compilers once per source file and passes multiple \fB\-arch\fP flags, leading to a single object file which will be a universal binary. Such object files work well when listed in the \fBIMPORTED_OBJECTS\fP of a separate CMake build, even for the \fI\%Xcode\fP generator. But producing such object files with the \fI\%Xcode\fP generator is more difficult, since it invokes the compiler once per architecture for each source file. Unlike the other generators, it does not generate universal object file binaries. .sp A further complication with the \fI\%Xcode\fP generator is that when targeting device platforms (iOS, tvOS, visionOS or watchOS), the \fI\%Xcode\fP generator has the ability to use either the device or simulator SDK without needing CMake to be re\-run. The SDK can be selected at build time. But since some architectures can be supported by both the device and the simulator SDKs (e.g. \fBarm64\fP with Xcode 12 or later), not all combinations can be represented in a single universal binary. The only solution in this case is to have multiple object files. .sp \fBIMPORTED_OBJECTS\fP doesn\(aqt support generator expressions, so every file it lists needs to be valid for every architecture and SDK. If incorporating object files that are not universal binaries, the path and/or file name of each object file has to somehow encapsulate the different architectures and SDKs. With the \fI\%Xcode\fP generator, Xcode variables of the form \fB$(...)\fP can be used to represent these aspects and Xcode will substitute the appropriate values at build time. CMake doesn\(aqt interpret these variables and embeds them unchanged in the Xcode project file. \fB$(CURRENT_ARCH)\fP can be used to represent the architecture, while \fB$(EFFECTIVE_PLATFORM_NAME)\fP can be used to differentiate between SDKs. .sp The following shows one example of how these two variables can be used to refer to an object file whose location depends on both the SDK and the architecture: .INDENT 0.0 .INDENT 3.5 .sp .EX add_library(someObjs OBJECT IMPORTED) set_property(TARGET someObjs PROPERTY IMPORTED_OBJECTS # Quotes are required because of the () \(dq/path/to/somewhere/objects$(EFFECTIVE_PLATFORM_NAME)/$(CURRENT_ARCH)/func.o\(dq ) # Example paths: # /path/to/somewhere/objects\-iphoneos/arm64/func.o # /path/to/somewhere/objects\-iphonesimulator/x86_64/func.o .EE .UNINDENT .UNINDENT .sp In some cases, you may want to have configuration\-specific object files as well. The \fB$(CONFIGURATION)\fP Xcode variable is often used for this and can be used in conjunction with the others mentioned above: .INDENT 0.0 .INDENT 3.5 .sp .EX add_library(someObjs OBJECT IMPORTED) set_property(TARGET someObjs PROPERTY IMPORTED_OBJECTS \(dq/path/to/somewhere/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)/$(CURRENT_ARCH)/func.o\(dq ) # Example paths: # /path/to/somewhere/Release\-iphoneos/arm64/func.o # /path/to/somewhere/Debug\-iphonesimulator/x86_64/func.o .EE .UNINDENT .UNINDENT .sp When any Xcode variable is used, CMake is not able to fully evaluate the path(s) at configure time. One consequence of this is that the configuration\-specific \fI\%IMPORTED_OBJECTS_\fP properties cannot be used, since CMake cannot determine whether an object file exists at a particular \fB\fP location. The \fBIMPORTED_OBJECTS\fP property must be used for these situations and the configuration\-specific aspects of the path should be handled by the \fB$(CONFIGURATION)\fP Xcode variable. .SS IMPORTED_OBJECTS_ .sp New in version 3.9. .sp \fB\fP\-specific version of \fI\%IMPORTED_OBJECTS\fP property. .sp Configuration names correspond to those provided by the project from which the target is imported. .SS Xcode Generator Considerations .sp Do not use this \fB\fP\-specific property if you need to use Xcode variables like \fB$(CURRENT_ARCH)\fP or \fB$(EFFECTIVE_PLATFORM_NAME)\fP in the value. The \fB\fP\-specific properties will be ignored in such cases because CMake cannot determine whether a file exists at the configuration\-specific path at configuration time. For such cases, use \fI\%IMPORTED_OBJECTS\fP instead. .SS IMPORTED_SONAME .sp The \fBsoname\fP of an \fBIMPORTED\fP target of shared library type. .sp Set this to the \fBsoname\fP embedded in an imported shared library.

A target property that can be set to override the prefix (such as \fBlib\fP) on an import library name. .SS IMPORT_SUFFIX .sp What comes after the import library name. .sp Similar to the target property \fI\%SUFFIX\fP, but used for import libraries (typically corresponding to a \fBDLL\fP) instead of regular libraries. A target property that can be set to override the suffix (such as \fB\&.lib\fP) on an import library name. .SS INCLUDE_DIRECTORIES .sp List of preprocessor include file search directories. .sp This property specifies the list of directories given so far to the \fI\%target_include_directories()\fP command. In addition to accepting values from that command, values may be set directly on any target using the \fI\%set_property()\fP command. A target gets its initial value for this property from the value of the \fI\%INCLUDE_DIRECTORIES\fP directory property. Both directory and target property values are adjusted by calls to the \fI\%include_directories()\fP command. .sp The value of this property is used by the generators to set the include paths for the compiler. .sp Relative paths should not be added to this property directly. Use one of the commands above instead to handle relative paths. .sp Contents of \fBINCLUDE_DIRECTORIES\fP may use \fI\%cmake\-generator\-expressions(7)\fP with the syntax \fB$<...>\fP\&.

See the \fI\%cmake\-buildsystem(7)\fP manual for more on defining buildsystem properties. .SS INSTALL_NAME_DIR .sp Directory name for installed targets on Apple platforms. .sp \fBINSTALL_NAME_DIR\fP is a string specifying the directory portion of the \(dqinstall_name\(dq field of shared libraries on Apple platforms for installed targets. When not set, the default directory used is determined by \fI\%MACOSX_RPATH\fP\&. If the \fI\%BUILD_WITH_INSTALL_NAME_DIR\fP property is set, this will be used already in the build tree. Policies \fI\%CMP0068\fP and \fI\%CMP0042\fP are also relevant. .sp This property is initialized by the value of the variable \fI\%CMAKE_INSTALL_NAME_DIR\fP if it is set when a target is created. .sp This property supports \fI\%generator expressions\fP\&. In particular, the \fI\%$\fP generator expression can be used to set the directory relative to the install\-time prefix. .sp On platforms that support runtime paths (\fBRPATH\fP), refer to the \fI\%INSTALL_RPATH\fP target property. Under Windows, the \fI\%TARGET_RUNTIME_DLLS\fP generator expression is related. .SS INSTALL_REMOVE_ENVIRONMENT_RPATH .sp New in version 3.16. .sp Controls whether toolchain\-defined rpaths should be removed during installation. .sp When a target is being installed, CMake may need to rewrite its rpath information. This occurs when the install rpath (as specified by the \fI\%INSTALL_RPATH\fP target property) has different contents to the rpath that the target was built with. Some toolchains insert their own rpath contents into the binary as part of the build. By default, CMake will preserve those extra inserted contents in the install rpath. For those scenarios where such toolchain\-inserted entries need to be discarded during install, set the \fBINSTALL_REMOVE_ENVIRONMENT_RPATH\fP target property to true. .sp This property is initialized by the value of \fI\%CMAKE_INSTALL_REMOVE_ENVIRONMENT_RPATH\fP when the target is created. .SS INSTALL_RPATH .sp The rpath to use for installed targets. .sp By default, the install rpath is empty. It can be set using this property, which is a semicolon\-separated list specifying the rpath to use in installed targets (for platforms that support it). This property is initialized by the value of the variable \fI\%CMAKE_INSTALL_RPATH\fP if it is set when a target is created. Beside setting the install rpath manually, using the \fI\%INSTALL_RPATH_USE_LINK_PATH\fP target property it can also be generated automatically by CMake. .sp Normally CMake uses the build tree for the RPATH when building executables etc on systems that use RPATH, see the \fI\%BUILD_RPATH\fP target property. When the software is installed the targets are edited (or relinked) by CMake (see \fI\%CMAKE_NO_BUILTIN_CHRPATH\fP) to have the install RPATH. This editing during installation can be avoided via the \fI\%BUILD_WITH_INSTALL_RPATH\fP target property. .sp For handling toolchain\-dependent RPATH entries the \fI\%INSTALL_REMOVE_ENVIRONMENT_RPATH\fP can be used. Runtime paths can be disabled completely via the \fI\%CMAKE_SKIP_RPATH\fP variable. .sp Because the rpath may contain \fB${ORIGIN}\fP, which coincides with CMake syntax, the contents of \fBINSTALL_RPATH\fP are properly escaped in the \fBcmake_install.cmake\fP script (see policy \fI\%CMP0095\fP\&.) .sp This property supports \fI\%generator expressions\fP\&. .sp On Apple platforms, refer to the \fI\%INSTALL_NAME_DIR\fP target property. Under Windows, the \fI\%TARGET_RUNTIME_DLLS\fP generator expression is related. .SS INSTALL_RPATH_USE_LINK_PATH .sp Add paths to linker search and installed rpath. .sp \fBINSTALL_RPATH_USE_LINK_PATH\fP is a boolean that if set to \fBTRUE\fP will append to the runtime search path (rpath) of installed binaries any directories outside the project that are in the linker search path or contain linked library files. The directories are appended after the value of the \fI\%INSTALL_RPATH\fP target property. .sp This property is initialized by the value of the variable \fI\%CMAKE_INSTALL_RPATH_USE_LINK_PATH\fP if it is set when a target is created. .SS INTERFACE_AUTOMOC_MACRO_NAMES .sp New in version 3.27. .sp A \fI\%semicolon\-separated list\fP of macro names for \fI\%AUTOMOC\fP to be propagated to consumers. .sp When a target with \fI\%AUTOMOC\fP enabled links to a library that sets \fBINTERFACE_AUTOMOC_MACRO_NAMES\fP, the target inherits the listed macro names and merges them with those specified in its own \fI\%AUTOMOC_MACRO_NAMES\fP property.

Static libraries need to use \fI\%STATIC_LIBRARY_OPTIONS\fP or \fI\%STATIC_LIBRARY_FLAGS\fP properties. .sp The \fBLINK_FLAGS\fP property, managed as a string, can be used to add extra flags to the link step of a target. \fI\%LINK_FLAGS_\fP will add to the configuration \fB\fP, for example, \fBDEBUG\fP, \fBRELEASE\fP, \fBMINSIZEREL\fP, \fBRELWITHDEBINFO\fP, ... .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 This property has been superseded by \fI\%LINK_OPTIONS\fP property. .UNINDENT .UNINDENT .SS LINK_FLAGS_ .sp Per\-configuration linker flags for a \fBSHARED\fP library, \fBMODULE\fP or \fBEXECUTABLE\fP target. .sp This is the configuration\-specific version of \fI\%LINK_FLAGS\fP\&. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 This property has been superseded by \fI\%LINK_OPTIONS\fP property. .UNINDENT .UNINDENT .SS LINK_INTERFACE_LIBRARIES .sp List public interface libraries for a shared library or executable. .sp By default linking to a shared library target transitively links to targets with which the library itself was linked. For an executable with exports (see the \fI\%ENABLE_EXPORTS\fP target property) no default transitive link dependencies are used. This property replaces the default transitive link dependencies with an explicit list. When the target is linked into another target using the \fI\%target_link_libraries()\fP command, the libraries listed (and recursively their link interface libraries) will be provided to the other target also. If the list is empty then no transitive link dependencies will be incorporated when this target is linked into another target even if the default set is non\-empty.

CMake by default constructs the link line so that the linker will scan through the component at least twice. This property specifies the minimum number of scans if it is larger than the default. CMake uses the largest value specified by any target in a component. .SS LINK_INTERFACE_MULTIPLICITY_ .sp Per\-configuration repetition count for cycles of \fBSTATIC\fP libraries. .sp This is the configuration\-specific version of \fI\%LINK_INTERFACE_MULTIPLICITY\fP\&.

This tells the generators that the named libraries must be looked up in the scope of the caller rather than in the scope in which the \fB\fP was created.

CMake uses these options to set the link type for libraries whose full paths are not known or (in some cases) are in implicit link directories for the platform. By default CMake adds an option at the end of the library list (if necessary) to set the linker search type back to its starting type. This property switches the final linker search type to \fB\-Bstatic\fP regardless of how it started. .sp This property is initialized by the value of the variable \fI\%CMAKE_LINK_SEARCH_END_STATIC\fP if it is set when a target is created. .sp See also \fI\%LINK_SEARCH_START_STATIC\fP\&. .SS LINK_SEARCH_START_STATIC .sp Assume the linker looks for static libraries by default. .sp Some linkers support switches such as \fB\-Bstatic\fP and \fB\-Bdynamic\fP to determine whether to use static or shared libraries for \fB\-lXXX\fP options.

The path may contain a build\-system\-specific portion that is replaced at build time with the configuration getting built (such as \fB$(ConfigurationName)\fP in VS). In CMake 2.6 and above \fI\%add_custom_command()\fP automatically recognizes a target name in its \fBCOMMAND\fP and \fBDEPENDS\fP options and computes the target location.

Currently, all languages except C, C++, Objective\-C, Objective\-C++, assembly, and CUDA are assumed to produce side effects. However, side effects from one language are assumed not to be relevant to another (for example, a Fortran library is assumed to not have any side effects that are relevant for a Swift library.) .UNINDENT .sp As an example, assume you have a static Fortran library which depends on a static C library, which in turn depends on a static Fortran library. The top\-level Fortran library has optimization enabled, but the middle C library does not. If you build the top Fortran library, the bottom Fortran library will also build, but not the middle C library, since the C library does not have any side effects that are relevant for the Fortran library. However, if you build the middle C library, the bottom Fortran library will also build, even though it does not have any side effects that are relevant to the C library, since the C library does not have optimization enabled. .sp This property is initialized by the value of the \fI\%CMAKE_OPTIMIZE_DEPENDENCIES\fP variable when the target is created. .SS OSX_ARCHITECTURES .sp Target specific architectures for macOS. .sp The \fBOSX_ARCHITECTURES\fP property sets the target binary architecture for targets on macOS (\fB\-arch\fP).

If a path starts with a generator expression, it is expected to evaluate to an absolute path. Not doing so is considered undefined behavior. .sp Paths that are for files generated by the build will be treated as relative to the build directory of the target, if the path is not already specified as an absolute path. Note that whether a file is seen as generated may be affected by policy \fI\%CMP0118\fP\&. .sp If a path does not start with a generator expression, is not an absolute path and is not a generated file, it will be treated as relative to the location selected by the first of the following that matches: .INDENT 0.0 .IP \(bu 2 If a file by the specified path exists relative to the target\(aqs source directory, use that file. .IP \(bu 2 If policy \fI\%CMP0115\fP is not set to \fBNEW\fP, try appending each known source file extension to the path and check if that exists relative to the target\(aqs source directory. .IP \(bu 2 Repeat the above two steps, this time relative to the target\(aqs binary directory instead. .UNINDENT .sp Note that the above decisions are made at generation time, not build time. .sp See the \fI\%cmake\-buildsystem(7)\fP manual for more on defining buildsystem properties. .SS SOVERSION .sp What version number is this target. .sp For shared libraries \fI\%VERSION\fP and \fBSOVERSION\fP can be used to specify the build version and API version respectively. When building or installing appropriate symlinks are created if the platform supports symlinks and the linker supports so\-names. If only one of both is specified the missing is assumed to have the same version number. \fBSOVERSION\fP is ignored if \fI\%NO_SONAME\fP property is set. .SS Windows Versions .sp For shared libraries and executables on Windows the \fI\%VERSION\fP attribute is parsed to extract a \fB.\fP version number. These numbers are used as the image version of the binary. .SS Mach\-O Versions .sp For shared libraries and executables on Mach\-O systems (e.g. macOS, iOS), the \fBSOVERSION\fP property corresponds to the \fIcompatibility version\fP and \fI\%VERSION\fP corresponds to the \fIcurrent version\fP (unless Mach\-O specific overrides are provided, as discussed below). See the \fI\%FRAMEWORK\fP target property for an example. .sp For shared libraries, the \fI\%MACHO_COMPATIBILITY_VERSION\fP and \fI\%MACHO_CURRENT_VERSION\fP properties can be used to override the \fIcompatibility version\fP and \fIcurrent version\fP respectively.

The set of options is de\-duplicated to avoid repetition. .sp New in version 3.12: While beneficial for individual options, the de\-duplication step can break up option groups. For example, \fB\-option A \-option B\fP becomes \fB\-option A B\fP\&. One may specify a group of options using shell\-like quoting along with a \fBSHELL:\fP prefix. The \fBSHELL:\fP prefix is dropped, and the rest of the option string is parsed using the \fI\%separate_arguments()\fP \fBUNIX_COMMAND\fP mode. For example, \fB\(dqSHELL:\-option A\(dq \(dqSHELL:\-option B\(dq\fP becomes \fB\-option A \-option B\fP\&. .SS SUFFIX .sp What comes after the target name. .sp A target property that can be set to override the suffix (such as \fB\&.so\fP or \fB\&.exe\fP) on the name of a library, module or executable. .SS Swift_DEPENDENCIES_FILE .sp New in version 3.15. .sp This property sets the path for the Swift dependency file (swiftdep) for the target. If one is not specified, it will default to \fB.swiftdeps\fP\&. .SS Swift_LANGUAGE_VERSION .sp New in version 3.16. .sp This property sets the language version for the Swift sources in the target. If one is not specified, it will default to \fI\%CMAKE_Swift_LANGUAGE_VERSION\fP if specified, otherwise it is the latest version supported by the compiler. .SS Swift_MODULE_DIRECTORY .sp New in version 3.15. .sp Specify output directory for Swift modules provided by the target. .sp If the target contains Swift source files, this specifies the directory in which the modules will be placed. When this property is not set, the modules will be placed in the build directory corresponding to the target\(aqs source directory. If the variable \fI\%CMAKE_Swift_MODULE_DIRECTORY\fP is set when a target is created its value is used to initialize this property. .SS Swift_MODULE_NAME .sp New in version 3.15. .sp This property specifies the name of the Swift module. It is defaulted to the name of the target. .SS SYSTEM .sp New in version 3.25. .sp Specifies that a target is a system target. This has the following effects: .INDENT 0.0 .IP \(bu 2 Entries of \fI\%INTERFACE_INCLUDE_DIRECTORIES\fP are treated as system include directories when compiling consumers. Entries of \fI\%INTERFACE_SYSTEM_INCLUDE_DIRECTORIES\fP are not affected, and will always be treated as system include directories. .IP \(bu 2 On Apple platforms, If the \fI\%FRAMEWORK\fP target property is true, the frameworks directory is treated as system. .UNINDENT .sp For imported targets, this property defaults to true, which means that their \fI\%INTERFACE_INCLUDE_DIRECTORIES\fP and, if the \fI\%FRAMEWORK\fP target property is true, frameworks directory are treated as system directories by default. If their \fBSYSTEM\fP property is false, then their \fI\%INTERFACE_INCLUDE_DIRECTORIES\fP as well as frameworks will not be treated as system. Use the \fI\%EXPORT_NO_SYSTEM\fP property to change how a target\(aqs \fBSYSTEM\fP property is set when it is installed. .sp For non\-imported targets, this target property is initialized from the \fI\%SYSTEM\fP directory property when the target is created. .SS TYPE .sp The type of the target. .sp This read\-only property can be used to test the type of the given target. It will be one of \fBSTATIC_LIBRARY\fP, \fBMODULE_LIBRARY\fP, \fBSHARED_LIBRARY\fP, \fBOBJECT_LIBRARY\fP, \fBINTERFACE_LIBRARY\fP, \fBEXECUTABLE\fP or one of the internal target types. .SS UNITY_BUILD .sp New in version 3.16. .sp When this property is set to true, the target source files will be combined into batches for faster compilation. This is done by creating a (set of) unity sources which \fB#include\fP the original sources, then compiling these unity sources instead of the originals. This is known as a \fIUnity\fP or \fIJumbo\fP build. .sp CMake provides different algorithms for selecting which sources are grouped together into a \fIbucket\fP\&. Algorithm selection is decided by the \fI\%UNITY_BUILD_MODE\fP target property, which has the following acceptable values: .INDENT 0.0 .IP \(bu 2 \fBBATCH\fP When in this mode CMake determines which files are grouped together. The \fI\%UNITY_BUILD_BATCH_SIZE\fP property controls the upper limit on how many sources can be combined per unity source file. .IP \(bu 2 \fBGROUP\fP When in this mode each target explicitly specifies how to group source files. Each source file that has the same \fI\%UNITY_GROUP\fP value will be grouped together. Any sources that don\(aqt have this property will be compiled individually. The \fI\%UNITY_BUILD_BATCH_SIZE\fP property is ignored when using this mode. .UNINDENT .sp If no explicit \fI\%UNITY_BUILD_MODE\fP has been specified, CMake will default to \fBBATCH\fP\&. .sp Unity builds are not currently supported for all languages. CMake version 3.28.3 supports combining \fBC\fP and \fBCXX\fP source files. For targets that mix source files from more than one language, CMake will separate the languages such that each generated unity source file only contains sources for a single language. .sp This property is initialized by the value of the \fI\%CMAKE_UNITY_BUILD\fP variable when a target is created. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 Projects should not directly set the \fBUNITY_BUILD\fP property or its associated \fI\%CMAKE_UNITY_BUILD\fP variable to true. Depending on the capabilities of the build machine and compiler used, it might or might not be appropriate to enable unity builds. Therefore, this feature should be under developer control, which would normally be through the developer choosing whether or not to set the \fI\%CMAKE_UNITY_BUILD\fP variable on the \fI\%cmake(1)\fP command line or some other equivalent method. However, it IS recommended to set the \fBUNITY_BUILD\fP target property to false if it is known that enabling unity builds for the target can lead to problems. .UNINDENT .UNINDENT .SS ODR (One definition rule) errors .sp When multiple source files are included into one source file, as is done for unity builds, it can potentially lead to ODR errors. CMake provides a number of measures to help address such problems: .INDENT 0.0 .IP \(bu 2 Any source file that has a non\-empty \fI\%COMPILE_OPTIONS\fP, \fI\%COMPILE_DEFINITIONS\fP, \fI\%COMPILE_FLAGS\fP, or \fI\%INCLUDE_DIRECTORIES\fP source property will not be combined into a unity source. .IP \(bu 2 Any source file which is scanned for C++ module sources via \fI\%CXX_SCAN_FOR_MODULES\fP, \fI\%CXX_SCAN_FOR_MODULES\fP, or membership of a \fBCXX_MODULES\fP file set will not be combined into a unity source. See \fI\%cmake\-cxxmodules(7)\fP for details. .IP \(bu 2 Projects can prevent an individual source file from being combined into a unity source by setting its \fI\%SKIP_UNITY_BUILD_INCLUSION\fP source property to true. This can be a more effective way to prevent problems with specific files than disabling unity builds for an entire target. .IP \(bu 2 Projects can set \fI\%UNITY_BUILD_UNIQUE_ID\fP to cause a valid C\-identifier to be generated which is unique per file in a unity build. This can be used to avoid problems with anonymous namespaces in unity builds. .IP \(bu 2 The \fI\%UNITY_BUILD_CODE_BEFORE_INCLUDE\fP and \fI\%UNITY_BUILD_CODE_AFTER_INCLUDE\fP target properties can be used to inject code into the unity source files before and after every \fB#include\fP statement. .IP \(bu 2 The order of source files added to the target via commands like \fI\%add_library()\fP, \fI\%add_executable()\fP or \fI\%target_sources()\fP will be preserved in the generated unity source files. This can be used to manually enforce a specific grouping based on the \fI\%UNITY_BUILD_BATCH_SIZE\fP target property. .UNINDENT .SS UNITY_BUILD_BATCH_SIZE .sp New in version 3.16. .sp Specifies the maximum number of source files that can be combined into any one unity source file when unity builds are enabled by the \fI\%UNITY_BUILD\fP target property. The original source files will be distributed across as many unity source files as necessary to honor this limit. .sp The initial value for this property is taken from the \fI\%CMAKE_UNITY_BUILD_BATCH_SIZE\fP variable when the target is created. If that variable has not been set, the initial value will be 8. .sp The batch size needs to be selected carefully. If set too high, the size of the combined source files could result in the compiler using excessive memory or hitting other similar limits. In extreme cases, this can even result in build failure. On the other hand, if the batch size is too low, there will be little gain in build performance. .sp Although strongly discouraged, the batch size may be set to a value of 0 to combine all the sources for the target into a single unity file, regardless of how many sources are involved. This runs the risk of creating an excessively large unity source file and negatively impacting the build performance, so a value of 0 is not generally recommended. .SS UNITY_BUILD_CODE_AFTER_INCLUDE .sp New in version 3.16. .sp Code snippet which is included verbatim by the \fI\%UNITY_BUILD\fP feature just after every \fB#include\fP statement in the generated unity source files.

Selection is decided by this property, which has the following acceptable values: .INDENT 0.0 .TP .B \fBBATCH\fP When in this mode CMake determines which files are grouped together. The \fI\%UNITY_BUILD_BATCH_SIZE\fP property controls the upper limit on how many sources can be combined per unity source file. .sp Example usage: .INDENT 7.0 .INDENT 3.5 .sp .EX add_library(example_library source1.cxx source2.cxx source3.cxx source4.cxx) set_target_properties(example_library PROPERTIES UNITY_BUILD_MODE BATCH UNITY_BUILD_BATCH_SIZE 2 ) .EE .UNINDENT .UNINDENT .TP .B \fBGROUP\fP When in this mode each target explicitly specifies how to group source files.

The value of the defined symbol is unspecified, but it is unique per file path. .sp Given: .INDENT 0.0 .INDENT 3.5 .sp .EX set_target_properties(myTarget PROPERTIES UNITY_BUILD \(dqON\(dq UNITY_BUILD_UNIQUE_ID \(dqMY_UNITY_ID\(dq ) .EE .UNINDENT .UNINDENT .sp the \fBMY_UNITY_ID\fP symbol is defined to a unique per\-file value. .sp One known use case for this identifier is to disambiguate the variables in an anonymous namespace in a limited scope. Anonymous namespaces present a problem for unity builds because they are used to ensure that certain variables and declarations are scoped to a translation unit which is approximated by a single source file. When source files are combined in a unity build file, those variables in different files are combined in a single translation unit and the names clash. This property can be used to avoid that with code like the following: .INDENT 0.0 .INDENT 3.5 .sp .EX // Needed for when unity builds are disabled #ifndef MY_UNITY_ID #define MY_UNITY_ID #endif namespace { namespace MY_UNITY_ID { // The name \(aqi\(aq clashes (or could clash) with other // variables in other anonymous namespaces int i = 42; }} int use_var() { return MY_UNITY_ID::i; } .EE .UNINDENT .UNINDENT .sp The pseudonymous namespace is used within a truly anonymous namespace. On many platforms, this maintains the invariant that the symbols within do not get external linkage when performing a unity build. .SS VERIFY_INTERFACE_HEADER_SETS .sp New in version 3.24. .sp Used to verify that all headers in a target\(aqs \fBPUBLIC\fP and \fBINTERFACE\fP header sets can be included on their own. .sp When this property is set to true, and the target is an object library, static library, shared library, interface library, or executable with exports enabled, and the target has one or more \fBPUBLIC\fP or \fBINTERFACE\fP header sets, an object library target named \fB_verify_interface_header_sets\fP is created. This verification target has one source file per header in the \fBPUBLIC\fP and \fBINTERFACE\fP header sets. Each source file only includes its associated header file. The verification target links against the original target to get all of its usage requirements. The verification target has its \fI\%EXCLUDE_FROM_ALL\fP and \fI\%DISABLE_PRECOMPILE_HEADERS\fP properties set to true, and its \fI\%AUTOMOC\fP, \fI\%AUTORCC\fP, \fI\%AUTOUIC\fP, and \fI\%UNITY_BUILD\fP properties set to false. .sp If the header\(aqs \fI\%LANGUAGE\fP property is set, the value of that property is used to determine the language with which to compile the header file. Otherwise, if the target has any C++ sources, the header is compiled as C++. Otherwise, if the target has any C sources, the header is compiled as C. Otherwise, if C++ is enabled globally, the header is compiled as C++. Otherwise, if C is enabled globally, the header is compiled as C. Otherwise, the header file is not compiled. .sp If the header\(aqs \fI\%SKIP_LINTING\fP property is set to true, the file is not compiled. .sp If any verification targets are created, a top\-level target called \fBall_verify_interface_header_sets\fP is created which depends on all verification targets. .sp This property is initialized by the value of the \fI\%CMAKE_VERIFY_INTERFACE_HEADER_SETS\fP variable if it is set when a target is created. .sp If the project wishes to control which header sets are verified by this property, it can set \fI\%INTERFACE_HEADER_SETS_TO_VERIFY\fP\&. .SS VERSION .sp What version number is this target. .sp For shared libraries \fBVERSION\fP and \fI\%SOVERSION\fP can be used to specify the build version and API version respectively. When building or installing appropriate symlinks are created if the platform supports symlinks and the linker supports so\-names. If only one of both is specified the missing is assumed to have the same version number. For executables \fBVERSION\fP can be used to specify the build version. When building or installing appropriate symlinks are created if the platform supports symlinks. .SS Windows Versions .sp For shared libraries and executables on Windows the \fBVERSION\fP attribute is parsed to extract a \fB.\fP version number. These numbers are used as the image version of the binary. .SS Mach\-O Versions .sp For shared libraries and executables on Mach\-O systems (e.g. macOS, iOS), the \fI\%SOVERSION\fP property corresponds to the \fIcompatibility version\fP and \fBVERSION\fP corresponds to the \fIcurrent version\fP (unless Mach\-O specific overrides are provided, as discussed below). See the \fI\%FRAMEWORK\fP target property for an example. .sp For shared libraries, the \fI\%MACHO_COMPATIBILITY_VERSION\fP and \fI\%MACHO_CURRENT_VERSION\fP properties can be used to override the \fIcompatibility version\fP and \fIcurrent version\fP respectively. Note that \fI\%SOVERSION\fP will still be used to form the \fBinstall_name\fP and both \fI\%SOVERSION\fP and \fBVERSION\fP may also affect the file and symlink names. .sp Versions of Mach\-O binaries may be checked with the \fBotool \-L \fP command. .SS VISIBILITY_INLINES_HIDDEN .sp Whether to add a compile flag to hide symbols of inline functions .sp The \fBVISIBILITY_INLINES_HIDDEN\fP property determines whether a flag for hiding symbols for inline functions, such as \fB\-fvisibility\-inlines\-hidden\fP, should be used when invoking the compiler. This property affects compilation in sources of all types of targets (subject to policy \fI\%CMP0063\fP). .sp This property is initialized by the value of the \fI\%CMAKE_VISIBILITY_INLINES_HIDDEN\fP variable if it is set when a target is created. .SS VS_CONFIGURATION_TYPE .sp New in version 3.6. .sp Visual Studio project configuration type. .sp Sets the \fBConfigurationType\fP attribute for a generated Visual Studio project.

The module definition file will be passed to the linker causing all symbols to be exported from the \fB\&.dll\fP\&. For global \fIdata\fP symbols, \fB__declspec(dllimport)\fP must still be used when compiling against the code in the \fB\&.dll\fP\&. All other function symbols will be automatically exported and imported by callers. This simplifies porting projects to Windows by reducing the need for explicit \fBdllexport\fP markup, even in \fBC++\fP classes. .sp When this property is enabled, zero or more \fB\&.def\fP files may also be specified as source files of the target. The exports named by these files will be merged with those detected from the object files to generate a single module definition file to be passed to the linker. This can be used to export symbols from a \fB\&.dll\fP that are not in any of its object files but are added by the linker from dependencies (e.g. \fBmsvcrt.lib\fP). .sp This property is initialized by the value of the \fI\%CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS\fP variable if it is set when a target is created. .SS XCODE_ATTRIBUTE_ .sp Set Xcode target attributes directly. .sp Tell the \fI\%Xcode\fP generator to set \fB\fP to a given value in the generated Xcode project.

If there are multiple cleanup tests for a fixture, projects can control their order with the usual \fI\%DEPENDS\fP test property if necessary. .sp A cleanup test is allowed to require other fixtures, but not any fixture listed in its \fBFIXTURES_CLEANUP\fP property.

Fixture names are case sensitive and they are not required to have any similarity to test names. .sp Fixtures are a way to attach setup and cleanup tasks to a set of tests. If a test requires a given fixture, then all tests marked as setup tasks for that fixture will be executed first (once for the whole set of tests, not once per test requiring the fixture). After all tests requiring a particular fixture have completed, CTest will ensure all tests marked as cleanup tasks for that fixture are then executed. Tests are marked as setup tasks with the \fI\%FIXTURES_SETUP\fP property and as cleanup tasks with the \fI\%FIXTURES_CLEANUP\fP property. If any of a fixture\(aqs setup tests fail, all tests listing that fixture in their \fBFIXTURES_REQUIRED\fP property will not be executed. The cleanup tests for the fixture will always be executed, even if some setup tests fail. .sp When CTest is asked to execute only a subset of tests (e.g. by the use of regular expressions or when run with the \fI\%\-\-rerun\-failed\fP command line option), it will automatically add any setup or cleanup tests for fixtures required by any of the tests that are in the execution set. This behavior can be overridden with the \fI\%\-FS\fP, \fI\%\-FC\fP and \fI\%\-FA\fP command line options to \fI\%ctest(1)\fP if desired. .sp Since setup and cleanup tasks are also tests, they can have an ordering specified by the \fI\%DEPENDS\fP test property just like any other tests. This can be exploited to implement setup or cleanup using multiple tests for a single fixture to modularise setup or cleanup logic. .sp The concept of a fixture is different to that of a resource specified by \fI\%RESOURCE_LOCK\fP, but they may be used together. A fixture defines a set of tests which share setup and cleanup requirements, whereas a resource lock has the effect of ensuring a particular set of tests do not run in parallel. Some situations may need both, such as setting up a database, serializing test access to that database and deleting the database again at the end. For such cases, tests would populate both \fBFIXTURES_REQUIRED\fP and \fI\%RESOURCE_LOCK\fP to combine the two behaviors. Names used for \fI\%RESOURCE_LOCK\fP have no relationship with names of fixtures, so note that a resource lock does not imply a fixture and vice versa. .sp Consider the following example which represents a database test scenario similar to that mentioned above: .INDENT 0.0 .INDENT 3.5 .sp .EX add_test(NAME testsDone COMMAND emailResults) add_test(NAME fooOnly COMMAND testFoo) add_test(NAME dbOnly COMMAND testDb) add_test(NAME dbWithFoo COMMAND testDbWithFoo) add_test(NAME createDB COMMAND initDB) add_test(NAME setupUsers COMMAND userCreation) add_test(NAME cleanupDB COMMAND deleteDB) add_test(NAME cleanupFoo COMMAND removeFoos) set_tests_properties(setupUsers PROPERTIES DEPENDS createDB) set_tests_properties(createDB PROPERTIES FIXTURES_SETUP DB) set_tests_properties(setupUsers PROPERTIES FIXTURES_SETUP DB) set_tests_properties(cleanupDB PROPERTIES FIXTURES_CLEANUP DB) set_tests_properties(cleanupFoo PROPERTIES FIXTURES_CLEANUP Foo) set_tests_properties(testsDone PROPERTIES FIXTURES_CLEANUP \(dqDB;Foo\(dq) set_tests_properties(fooOnly PROPERTIES FIXTURES_REQUIRED Foo) set_tests_properties(dbOnly PROPERTIES FIXTURES_REQUIRED DB) set_tests_properties(dbWithFoo PROPERTIES FIXTURES_REQUIRED \(dqDB;Foo\(dq) set_tests_properties(dbOnly dbWithFoo createDB setupUsers cleanupDB PROPERTIES RESOURCE_LOCK DbAccess) .EE .UNINDENT .UNINDENT .sp Key points from this example: .INDENT 0.0 .IP \(bu 2 Two fixtures are defined: \fBDB\fP and \fBFoo\fP\&. Tests can require a single fixture as \fBfooOnly\fP and \fBdbOnly\fP do, or they can depend on multiple fixtures like \fBdbWithFoo\fP does. .IP \(bu 2 A \fBDEPENDS\fP relationship is set up to ensure \fBsetupUsers\fP happens after \fBcreateDB\fP, both of which are setup tests for the \fBDB\fP fixture and will therefore be executed before the \fBdbOnly\fP and \fBdbWithFoo\fP tests automatically. .IP \(bu 2 No explicit \fBDEPENDS\fP relationships were needed to make the setup tests run before or the cleanup tests run after the regular tests. .IP \(bu 2 The \fBFoo\fP fixture has no setup tests defined, only a single cleanup test. .IP \(bu 2 \fBtestsDone\fP is a cleanup test for both the \fBDB\fP and \fBFoo\fP fixtures. Therefore, it will only execute once regular tests for both fixtures have finished (i.e. after \fBfooOnly\fP, \fBdbOnly\fP and \fBdbWithFoo\fP). No \fBDEPENDS\fP relationship was specified for \fBtestsDone\fP, so it is free to run before, after or concurrently with other cleanup tests for either fixture. .IP \(bu 2 The setup and cleanup tests never list the fixtures they are for in their own \fBFIXTURES_REQUIRED\fP property, as that would result in a dependency on themselves and be considered an error. .UNINDENT .SS FIXTURES_SETUP .sp New in version 3.7. .sp Specifies a list of fixtures for which the test is to be treated as a setup test. These fixture names are distinct from test case names and are not required to have any similarity to the names of tests associated with them. .sp Fixture setup tests are ordinary tests with all of the usual test functionality. Setting the \fBFIXTURES_SETUP\fP property for a test has two primary effects: .INDENT 0.0 .IP \(bu 2 CTest will ensure the test executes before any other test which lists the fixture name(s) in its \fI\%FIXTURES_REQUIRED\fP property. .IP \(bu 2 If CTest is asked to run only a subset of tests (e.g. using regular expressions or the \fB\-\-rerun\-failed\fP option) and the setup test is not in the set of tests to run, it will automatically be added if any tests in the set require any fixture listed in \fBFIXTURES_SETUP\fP\&. .UNINDENT .sp A setup test can have multiple fixtures listed in its \fBFIXTURES_SETUP\fP property.

The labels are reported in both the \fBctest\fP output summary and in dashboard submissions. They can also be used to filter the set of tests to be executed (see the \fI\%ctest \-L\fP and \fI\%ctest \-LE\fP options). .sp See \fI\%Additional Labels\fP for adding labels to a test dynamically during test execution. .SS MEASUREMENT .sp Specify a \fBCDASH\fP measurement and value to be reported for a test. .sp If set to a name then that name will be reported to \fBCDASH\fP as a named measurement with a value of \fB1\fP\&. You may also specify a value by setting \fBMEASUREMENT\fP to \fBmeasurement=value\fP\&. .SS PASS_REGULAR_EXPRESSION .sp The output must match this regular expression for the test to pass. The process exit code is ignored. .sp If set, the test output will be checked against the specified regular expressions and at least one of the regular expressions has to match, otherwise the test will fail. Example: .INDENT 0.0 .INDENT 3.5 .sp .EX set_tests_properties(mytest PROPERTIES PASS_REGULAR_EXPRESSION \(dqTestPassed;All ok\(dq ) .EE .UNINDENT .UNINDENT .sp \fBPASS_REGULAR_EXPRESSION\fP expects a list of regular expressions. .sp See also the \fI\%FAIL_REGULAR_EXPRESSION\fP and \fI\%SKIP_REGULAR_EXPRESSION\fP test properties. .SS PROCESSOR_AFFINITY .sp New in version 3.12. .sp Set to a true value to ask CTest to launch the test process with CPU affinity for a fixed set of processors. If enabled and supported for the current platform, CTest will choose a set of processors to place in the CPU affinity mask when launching the test process. The number of processors in the set is determined by the \fI\%PROCESSORS\fP test property or the number of processors available to CTest, whichever is smaller. The set of processors chosen will be disjoint from the processors assigned to other concurrently running tests that also have the \fBPROCESSOR_AFFINITY\fP property enabled. .SS PROCESSORS .sp Set to specify how many process slots this test requires. If not set, the default is \fB1\fP processor. .sp Denotes the number of processors that this test will require. This is typically used for MPI tests, and should be used in conjunction with the \fI\%ctest_test()\fP \fBPARALLEL_LEVEL\fP option. .sp This will also be used to display a weighted test timing result in label and subproject summaries in the command line output of \fI\%ctest(1)\fP\&. The wall clock time for the test run will be multiplied by this property to give a better idea of how much cpu resource CTest allocated for the test. .sp See also the \fI\%PROCESSOR_AFFINITY\fP test property. .SS REQUIRED_FILES .sp List of files required to run the test. The filenames are relative to the test \fI\%WORKING_DIRECTORY\fP unless an absolute path is specified. .sp If set to a list of files, the test will not be run unless all of the files exist. .SS Examples .sp Suppose that \fBtest.txt\fP is created by test \fBbaseTest\fP and \fBnone.txt\fP does not exist: .INDENT 0.0 .INDENT 3.5 .sp .EX add_test(NAME baseTest ...) # Assumed to create test.txt add_test(NAME fileTest ...) # The following ensures that if baseTest is successful, test.txt will # have been created before fileTest is run set_tests_properties(fileTest PROPERTIES DEPENDS baseTest REQUIRED_FILES test.txt ) add_test(NAME notRunTest ...) # The following makes notRunTest depend on two files. Nothing creates # the none.txt file, so notRunTest will fail with status \(dqNot Run\(dq. set_tests_properties(notRunTest PROPERTIES REQUIRED_FILES \(dqtest.txt;none.txt\(dq ) .EE .UNINDENT .UNINDENT .sp The above example demonstrates how \fBREQUIRED_FILES\fP works, but it is not the most robust way to implement test ordering with failure detection. For that, test fixtures are a better alternative (see \fI\%FIXTURES_REQUIRED\fP). .SS RESOURCE_GROUPS .sp New in version 3.16. .sp Specify resources required by a test, grouped in a way that is meaningful to the test. See \fI\%resource allocation\fP for more information on how this property integrates into the CTest resource allocation feature. .sp The \fBRESOURCE_GROUPS\fP property is a \fI\%semicolon\-separated list\fP of group descriptions. Each entry consists of an optional number of groups using the description followed by a series of resource requirements for those groups. These requirements (and the number of groups) are separated by commas. The resource requirements consist of the name of a resource type, followed by a colon, followed by an unsigned integer specifying the number of slots required on one resource of the given type. .sp The \fBRESOURCE_GROUPS\fP property tells CTest what resources a test expects to use grouped in a way meaningful to the test. The test itself must read the \fI\%environment variables\fP to determine which resources have been allocated to each group. For example, each group may correspond to a process the test will spawn when executed. .sp Consider the following example: .INDENT 0.0 .INDENT 3.5 .sp .EX add_test(NAME MyTest COMMAND MyExe) set_property(TEST MyTest PROPERTY RESOURCE_GROUPS \(dq2,gpus:2\(dq \(dqgpus:4,crypto_chips:2\(dq) .EE .UNINDENT .UNINDENT .sp In this example, there are two group descriptions (implicitly separated by a semicolon.) The content of the first description is \fB2,gpus:2\fP\&. This description specifies 2 groups, each of which requires 2 slots from a single GPU. The content of the second description is \fBgpus:4,crypto_chips:2\fP\&. This description does not specify a group count, so a default of 1 is assumed. This single group requires 4 slots from a single GPU and 2 slots from a single cryptography chip. In total, 3 resource groups are specified for this test, each with its own unique requirements. .sp Note that the number of slots following the resource type specifies slots from a \fIsingle\fP instance of the resource. If the resource group can tolerate receiving slots from different instances of the same resource, it can indicate this by splitting the specification into multiple requirements of one slot. For example: .INDENT 0.0 .INDENT 3.5 .sp .EX add_test(NAME MyTest COMMAND MyExe) set_property(TEST MyTest PROPERTY RESOURCE_GROUPS \(dqgpus:1,gpus:1,gpus:1,gpus:1\(dq) .EE .UNINDENT .UNINDENT .sp In this case, the single resource group indicates that it needs four GPU slots, all of which may come from separate GPUs (though they don\(aqt have to; CTest may still assign slots from the same GPU.) .sp When CTest sets the \fI\%environment variables\fP for a test, it assigns a group number based on the group description, starting at 0 on the left and the number of groups minus 1 on the right. For example, in the example above, the two groups in the first description would have IDs of 0 and 1, and the single group in the second description would have an ID of 2. .sp Both the \fBRESOURCE_GROUPS\fP and \fI\%RESOURCE_LOCK\fP properties serve similar purposes, but they are distinct and orthogonal. Resources specified by \fBRESOURCE_GROUPS\fP do not affect \fI\%RESOURCE_LOCK\fP, and vice versa. Whereas \fI\%RESOURCE_LOCK\fP is a simpler property that is used for locking one global resource, \fBRESOURCE_GROUPS\fP is a more advanced property that allows multiple tests to simultaneously use multiple resources of the same type, specifying their requirements in a fine\-grained manner. .SS RESOURCE_LOCK .sp Specify a list of resources that are locked by this test. .sp If multiple tests specify the same resource lock, they are guaranteed not to run concurrently. .sp See also \fI\%FIXTURES_REQUIRED\fP if the resource requires any setup or cleanup steps. .sp Both the \fI\%RESOURCE_GROUPS\fP and \fBRESOURCE_LOCK\fP properties serve similar purposes, but they are distinct and orthogonal. Resources specified by \fI\%RESOURCE_GROUPS\fP do not affect \fBRESOURCE_LOCK\fP, and vice versa. Whereas \fBRESOURCE_LOCK\fP is a simpler property that is used for locking one global resource, \fI\%RESOURCE_GROUPS\fP is a more advanced property that allows multiple tests to simultaneously use multiple resources of the same type, specifying their requirements in a fine\-grained manner. .SS RUN_SERIAL .sp Do not run this test in parallel with any other test. .sp Use this option in conjunction with the ctest_test \fBPARALLEL_LEVEL\fP option to specify that this test should not be run in parallel with any other tests. .SS SKIP_REGULAR_EXPRESSION .sp New in version 3.16. .sp If the output matches this regular expression the test will be marked as skipped. .sp If set, if the output matches one of specified regular expressions, the test will be marked as skipped.

If such a situation should not be considered a hard failure a return code of the process can be specified that will mark the test as \fBNot Run\fP if it is encountered. Valid values are in the range of 0 to 255, inclusive. .sp See also the \fI\%SKIP_REGULAR_EXPRESSION\fP property. .SS TIMEOUT .sp How many seconds to allow for this test. .sp This property if set will limit a test to not take more than the specified number of seconds to run. If it exceeds that the test process will be killed and ctest will move to the next test. This setting takes precedence over \fI\%CTEST_TEST_TIMEOUT\fP\&. .sp An explicit \fB0\fP value means the test has no timeout, except as necessary to honor \fI\%ctest \-\-stop\-time\fP\&. .sp See also \fI\%TIMEOUT_AFTER_MATCH\fP and \fI\%TIMEOUT_SIGNAL_NAME\fP\&. .SS TIMEOUT_AFTER_MATCH .sp New in version 3.6. .sp Change a test\(aqs timeout duration after a matching line is encountered in its output. .SS Usage .INDENT 0.0 .INDENT 3.5 .sp .EX add_test(mytest ...) set_property(TEST mytest PROPERTY TIMEOUT_AFTER_MATCH \(dq${seconds}\(dq \(dq${regex}\(dq) .EE .UNINDENT .UNINDENT .SS Description .sp Allow a test \fBseconds\fP to complete after \fBregex\fP is encountered in its output. .sp When the test outputs a line that matches \fBregex\fP its start time is reset to the current time and its timeout duration is changed to \fBseconds\fP\&. Prior to this, the timeout duration is determined by the \fI\%TIMEOUT\fP property or the \fI\%CTEST_TEST_TIMEOUT\fP variable if either of these are set. Because the test\(aqs start time is reset, its execution time will not include any time that was spent waiting for the matching output. .sp \fBTIMEOUT_AFTER_MATCH\fP is useful for avoiding spurious timeouts when your test must wait for some system resource to become available before it can execute. Set \fI\%TIMEOUT\fP to a longer duration that accounts for resource acquisition and use \fBTIMEOUT_AFTER_MATCH\fP to control how long the actual test is allowed to run. .sp If the required resource can be controlled by CTest you should use \fI\%RESOURCE_LOCK\fP instead of \fBTIMEOUT_AFTER_MATCH\fP\&. This property should be used when only the test itself can determine when its required resources are available. .sp See also \fI\%TIMEOUT_SIGNAL_NAME\fP\&. .SS TIMEOUT_SIGNAL_GRACE_PERIOD .sp New in version 3.27. .sp If the \fI\%TIMEOUT_SIGNAL_NAME\fP test property is set, this property specifies the number of seconds to wait for a test process to terminate after sending the custom signal. Otherwise, this property has no meaning. .sp The grace period may be any real value greater than \fB0.0\fP, but not greater than \fB60.0\fP\&. If this property is not set, the default is \fB1.0\fP second. .sp This is available only on platforms supporting POSIX signals.

CMake will automatically escape the value correctly for the native build system (note that CMake language syntax may require escapes to specify some values). This property may be set on a per\-configuration basis using the name \fBCOMPILE_DEFINITIONS_\fP where \fB\fP is an upper\-case name (ex. \fBCOMPILE_DEFINITIONS_DEBUG\fP). .sp CMake will automatically drop some definitions that are not supported by the native build tool.

However, \fI\%Xcode\fP does not support per\-config per\-source settings, so expressions that depend on the build configuration are not allowed with that generator. .sp Usage example: .INDENT 0.0 .INDENT 3.5 .sp .EX set_source_files_properties(foo.cpp PROPERTIES COMPILE_OPTIONS \(dq\-Wno\-unused\-parameter;\-Wno\-missing\-field\-initializer\(dq) .EE .UNINDENT .UNINDENT .sp Related properties: .INDENT 0.0 .IP \(bu 2 Prefer this property over \fI\%COMPILE_FLAGS\fP\&. .IP \(bu 2 Use \fI\%COMPILE_DEFINITIONS\fP to pass additional preprocessor definitions. .IP \(bu 2 Use \fI\%INCLUDE_DIRECTORIES\fP to pass additional include directories. .UNINDENT .sp Related commands: .INDENT 0.0 .IP \(bu 2 \fI\%add_compile_options()\fP for directory\-wide settings .IP \(bu 2 \fI\%target_compile_options()\fP for target\-specific settings .UNINDENT .SS CXX_SCAN_FOR_MODULES .sp New in version 3.28. .sp \fBCXX_SCAN_FOR_MODULES\fP is a boolean specifying whether CMake will scan the source for C++ module dependencies. See also the \fI\%CXX_SCAN_FOR_MODULES\fP for target\-wide settings. .sp When this property is set \fBON\fP, CMake will scan the source at build time and add module dependency information to the compile line as necessary. When this property is set \fBOFF\fP, CMake will not scan the source at build time. When this property is unset, the \fI\%CXX_SCAN_FOR_MODULES\fP property is consulted. .sp Note that scanning is only performed if C++20 or higher is enabled for the target and the source uses the \fBCXX\fP language. Scanning for modules in sources belonging to file sets of type \fBCXX_MODULES\fP is always performed. .SS EXTERNAL_OBJECT .sp If set to true then this is an object file. .sp If this property is set to \fBTrue\fP then the source file is really an object file and should not be compiled. It will still be linked into the target though. .SS Fortran_FORMAT .sp Set to \fBFIXED\fP or \fBFREE\fP to indicate the Fortran source layout. .sp This property tells CMake whether a given Fortran source file uses fixed\-format or free\-format. CMake will pass the corresponding format flag to the compiler. Consider using the target\-wide \fI\%Fortran_FORMAT\fP property if all source files in a target share the same format. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 For some compilers, \fBNAG\fP, \fBPGI\fP and \fBSolaris Studio\fP, setting this to \fBOFF\fP will have no effect. .UNINDENT .UNINDENT .SS Fortran_PREPROCESS .sp New in version 3.18. .sp Control whether the Fortran source file should be unconditionally preprocessed. .sp If unset or empty, rely on the compiler to determine whether the file should be preprocessed. If explicitly set to \fBOFF\fP then the file does not need to be preprocessed. If explicitly set to \fBON\fP, then the file does need to be preprocessed as part of the compilation step. .sp When using the \fI\%Ninja\fP generator, all source files are first preprocessed in order to generate module dependency information. Setting this property to \fBOFF\fP will make \fBNinja\fP skip this step. .sp Consider using the target\-wide \fI\%Fortran_PREPROCESS\fP property if all source files in a target need to be preprocessed. .SS GENERATED .sp Is this source file generated as part of the build or CMake process. .sp Changed in version 3.20: The GENERATED source file property is now visible in all directories. .sp Tells the internal CMake engine that a source file is generated by an outside process such as another build step, or the execution of CMake itself. This information is then used to exempt the file from any existence or validity checks. .sp Any file that is .INDENT 0.0 .IP \(bu 2 created by the execution of commands such as \fI\%add_custom_command()\fP which run during the build .IP \(bu 2 listed as one of the \fBBYPRODUCTS\fP of an \fI\%add_custom_command()\fP or \fI\%add_custom_target()\fP command, or .IP \(bu 2 created by a CMake \fBAUTOGEN\fP operation such as \fI\%AUTOMOC\fP, \fI\%AUTORCC\fP, or \fI\%AUTOUIC\fP .UNINDENT .sp will be marked with the \fBGENERATED\fP property. .sp When a generated file created as the \fBOUTPUT\fP of an \fI\%add_custom_command()\fP command is explicitly listed as a source file for any target in the same directory scope (which usually means the same \fBCMakeLists.txt\fP file), CMake will automatically create a dependency to make sure the file is generated before building that target. .sp The \fI\%Makefile Generators\fP will remove \fBGENERATED\fP files during \fBmake clean\fP\&. .sp Generated sources may be hidden in some IDE tools, while in others they might be shown. For the special case of sources generated by CMake\(aqs \fI\%AUTOMOC\fP, \fI\%AUTORCC\fP or \fI\%AUTOUIC\fP functionality, the \fI\%AUTOGEN_SOURCE_GROUP\fP, \fI\%AUTOMOC_SOURCE_GROUP\fP, \fI\%AUTORCC_SOURCE_GROUP\fP and \fI\%AUTOUIC_SOURCE_GROUP\fP target properties may influence where the generated sources are grouped in the project\(aqs file lists. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 Starting with CMake 3.20 the \fBGENERATED\fP source file property can be set and retrieved from any directory scope. It is an all\-or\-nothing property. It also can no longer be removed or unset if it was set to \fBTRUE\fP\&. Policy \fI\%CMP0118\fP was introduced to allow supporting the \fBOLD\fP behavior for some time. .UNINDENT .UNINDENT .SS HEADER_FILE_ONLY .sp Is this source file only a header file. .sp A property on a source file that indicates if the source file is a header file with no associated implementation. This is set automatically based on the file extension and is used by CMake to determine if certain dependency information should be computed. .sp By setting this property to \fBON\fP, you can disable compilation of the given source file, even if it should be compiled because it is part of the library\(aqs/executable\(aqs sources. .sp This is useful if you have some source files which you somehow pre\-process, and then add these pre\-processed sources via \fI\%add_library()\fP or \fI\%add_executable()\fP\&. Normally, in IDE, there would be no reference of the original sources, only of these pre\-processed sources. So by setting this property for all the original source files to \fBON\fP, and then either calling \fI\%add_library()\fP or \fI\%add_executable()\fP while passing both the pre\-processed sources and the original sources, or by using \fI\%target_sources()\fP to add original source files will do exactly what would one expect, i.e. the original source files would be visible in IDE, and will not be built. .SS INCLUDE_DIRECTORIES .sp New in version 3.11. .sp List of preprocessor include file search directories. .sp This property holds a \fI\%semicolon\-separated list\fP of paths and will be added to the list of include directories when this source file builds. These directories will take precedence over directories defined at target level except for \fI\%Xcode\fP generator due to technical limitations. .sp Relative paths should not be added to this property directly. .sp Contents of \fBINCLUDE_DIRECTORIES\fP may use \(dqgenerator expressions\(dq with the syntax \fB$<...>\fP\&. See the \fI\%cmake\-generator\-expressions(7)\fP manual for available expressions. However, \fI\%Xcode\fP does not support per\-config per\-source settings, so expressions that depend on the build configuration are not allowed with that generator. .SS KEEP_EXTENSION .sp Make the output file have the same extension as the source file. .sp If this property is set then the file extension of the output file will be the same as that of the source file. Normally the output file extension is computed based on the language of the source file, for example \fB\&.cxx\fP will go to a \fB\&.o\fP extension. .SS LABELS .sp Specify a list of text labels associated with a source file. .sp This property has meaning only when the source file is listed in a target whose \fBLABELS\fP property is also set. No other semantics are currently specified. .SS LANGUAGE .sp Specify the programming language in which a source file is written. .sp A property that can be set to indicate what programming language the source file is. If it is not set the language is determined based on the file extension. Typical values are \fBCXX\fP (i.e. C++), \fBC\fP, \fBCSharp\fP, \fBCUDA\fP, \fBFortran\fP, \fBHIP\fP, \fBISPC\fP, and \fBASM\fP\&. Setting this property for a file means this file will be compiled, unless \fI\%HEADER_FILE_ONLY\fP is set. .sp Changed in version 3.20: Setting this property causes the source file to be compiled as the specified language, using explicit flags if possible. Previously it only caused the specified language\(aqs compiler to be used. See policy \fI\%CMP0119\fP\&. .SS LOCATION .sp The full path to a source file. .sp A read only property on a SOURCE FILE that contains the full path to the source file. .SS MACOSX_PACKAGE_LOCATION .sp Place a source file inside a Application Bundle (\fI\%MACOSX_BUNDLE\fP), Core Foundation Bundle (\fI\%BUNDLE\fP), or Framework Bundle (\fI\%FRAMEWORK\fP). It is applicable for macOS and iOS. .sp Executable targets with the \fI\%MACOSX_BUNDLE\fP property set are built as macOS or iOS application bundles on Apple platforms. Shared library targets with the \fI\%FRAMEWORK\fP property set are built as macOS or iOS frameworks on Apple platforms. Module library targets with the \fI\%BUNDLE\fP property set are built as macOS \fBCFBundle\fP bundles on Apple platforms. Source files listed in the target with this property set will be copied to a directory inside the bundle or framework content folder specified by the property value. For macOS Application Bundles the content folder is \fB.app/Contents\fP\&. For macOS Frameworks the content folder is \fB.framework/Versions/\fP\&. For macOS CFBundles the content folder is \fB.bundle/Contents\fP (unless the extension is changed). See the \fI\%PUBLIC_HEADER\fP, \fI\%PRIVATE_HEADER\fP, and \fI\%RESOURCE\fP target properties for specifying files meant for \fBHeaders\fP, \fBPrivateHeaders\fP, or \fBResources\fP directories. .sp If the specified location is equal to \fBResources\fP, the resulting location will be the same as if the \fI\%RESOURCE\fP property had been used. If the specified location is a sub\-folder of \fBResources\fP, it will be placed into the respective sub\-folder. Note: For iOS Apple uses a flat bundle layout where no \fBResources\fP folder exist. Therefore CMake strips the \fBResources\fP folder name from the specified location. .SS OBJECT_DEPENDS .sp Additional files on which a compiled object file depends. .sp Specifies a \fI\%semicolon\-separated list\fP of full\-paths to files on which any object files compiled from this source file depend. On \fI\%Makefile Generators\fP and the \fI\%Ninja\fP generator an object file will be recompiled if any of the named files is newer than it. \fI\%Visual Studio Generators\fP and the \fI\%Xcode\fP generator cannot implement such compilation dependencies. .sp This property need not be used to specify the dependency of a source file on a generated header file that it includes. Although the property was originally introduced for this purpose, it is no longer necessary. If the generated header file is created by a custom command in the same target as the source file, the automatic dependency scanning process will recognize the dependency. If the generated header file is created by another target, an inter\-target dependency should be created with the \fI\%add_dependencies()\fP command (if one does not already exist due to linking relationships). .SS OBJECT_OUTPUTS .sp Additional outputs for a \fI\%Ninja\fP or \fI\%Makefile Generators\fP rule. .sp Additional outputs created by compilation of this source file. If any of these outputs is missing the object will be recompiled. This is supported only on the \fI\%Ninja\fP and \fI\%Makefile Generators\fP and will be ignored on other generators. .sp This property supports \fI\%generator expressions\fP\&. .SS SKIP_AUTOGEN .sp New in version 3.8. .sp Exclude the source file from \fI\%AUTOMOC\fP, \fI\%AUTOUIC\fP and \fI\%AUTORCC\fP processing (for Qt projects). .sp For finer exclusion control see \fI\%SKIP_AUTOMOC\fP, \fI\%SKIP_AUTOUIC\fP and \fI\%SKIP_AUTORCC\fP\&. .SS EXAMPLE .INDENT 0.0 .INDENT 3.5 .sp .EX # ... set_property(SOURCE file.h PROPERTY SKIP_AUTOGEN ON) # ... .EE .UNINDENT .UNINDENT .SS SKIP_AUTOMOC .sp New in version 3.8. .sp Exclude the source file from \fI\%AUTOMOC\fP processing (for Qt projects). .sp For broader exclusion control see \fI\%SKIP_AUTOGEN\fP\&. .SS EXAMPLE .INDENT 0.0 .INDENT 3.5 .sp .EX # ... set_property(SOURCE file.h PROPERTY SKIP_AUTOMOC ON) # ... .EE .UNINDENT .UNINDENT .SS SKIP_AUTORCC .sp New in version 3.8. .sp Exclude the source file from \fI\%AUTORCC\fP processing (for Qt projects). .sp For broader exclusion control see \fI\%SKIP_AUTOGEN\fP\&. .SS EXAMPLE .INDENT 0.0 .INDENT 3.5 .sp .EX # ... set_property(SOURCE file.qrc PROPERTY SKIP_AUTORCC ON) # ... .EE .UNINDENT .UNINDENT .SS SKIP_AUTOUIC .sp New in version 3.8. .sp Exclude the source file from \fI\%AUTOUIC\fP processing (for Qt projects). .sp \fBSKIP_AUTOUIC\fP can be set on C++ header and source files and on \fB\&.ui\fP files. .sp For broader exclusion control see \fI\%SKIP_AUTOGEN\fP\&. .SS EXAMPLE .INDENT 0.0 .INDENT 3.5 .sp .EX # ... set_property(SOURCE file.h PROPERTY SKIP_AUTOUIC ON) set_property(SOURCE file.cpp PROPERTY SKIP_AUTOUIC ON) set_property(SOURCE widget.ui PROPERTY SKIP_AUTOUIC ON) # ... .EE .UNINDENT .UNINDENT .SS SKIP_LINTING .sp New in version 3.27. .sp This property allows you to exclude a specific source file from the linting process. The linting process involves running tools such as \fI\%_CPPLINT\fP, \fI\%_CLANG_TIDY\fP, \fI\%_CPPCHECK\fP, and \fI\%_INCLUDE_WHAT_YOU_USE\fP on the source files, as well as compiling header files as part of \fI\%VERIFY_INTERFACE_HEADER_SETS\fP\&. By setting \fBSKIP_LINTING\fP on a source file, the mentioned linting tools will not be executed for that particular file. .SS Example .sp Consider a C++ project that includes multiple source files, such as \fBmain.cpp\fP, \fBthings.cpp\fP, and \fBgeneratedBindings.cpp\fP\&. In this example, you want to exclude the \fBgeneratedBindings.cpp\fP file from the linting process. To achieve this, you can utilize the \fBSKIP_LINTING\fP property with the \fI\%set_source_files_properties()\fP command as shown below: .INDENT 0.0 .INDENT 3.5 .sp .EX add_executable(MyApp main.cpp things.cpp generatedBindings.cpp) set_source_files_properties(generatedBindings.cpp PROPERTIES SKIP_LINTING ON ) .EE .UNINDENT .UNINDENT .sp In the provided code snippet, the \fBSKIP_LINTING\fP property is set to true for the \fBgeneratedBindings.cpp\fP source file. As a result, when the linting tools specified by \fI\%_CPPLINT\fP, \fI\%_CLANG_TIDY\fP, \fI\%_CPPCHECK\fP, or \fI\%_INCLUDE_WHAT_YOU_USE\fP are executed, they will skip analyzing the \fBgeneratedBindings.cpp\fP file. .sp By using the \fBSKIP_LINTING\fP property, you can selectively exclude specific source files from the linting process. This allows you to focus the linting tools on the relevant parts of your project, enhancing the efficiency and effectiveness of the linting workflow. .SS SKIP_PRECOMPILE_HEADERS .sp New in version 3.16. .sp Is this source file skipped by \fI\%PRECOMPILE_HEADERS\fP feature. .sp This property helps with build problems that one would run into when using the \fI\%PRECOMPILE_HEADERS\fP feature. .sp One example would be the usage of Objective\-C (\fB*.m\fP) files, and Objective\-C++ (\fB*.mm\fP) files, which lead to compilation failure because they are treated (in case of Ninja / Makefile generator) as C, and CXX respectively. The precompile headers are not compatible between languages. .SS SKIP_UNITY_BUILD_INCLUSION .sp New in version 3.16. .sp Setting this property to true ensures the source file will be skipped by unity builds when its associated target has its \fI\%UNITY_BUILD\fP property set to true. The source file will instead be compiled on its own in the same way as it would with unity builds disabled. .sp This property helps with \(dqODR (One definition rule)\(dq problems where combining a particular source file with others might lead to build errors or other unintended side effects. .sp Note that sources which are scanned for C++ modules (see \fI\%cmake\-cxxmodules(7)\fP) are not eligible for unity build inclusion and will automatically be excluded. .SS Swift_DEPENDENCIES_FILE .sp New in version 3.15. .sp This property sets the path for the Swift dependency file (swiftdeps) for the source. If one is not specified, it will default to \fB.swiftdeps\fP\&. .SS Swift_DIAGNOSTICS_FILE .sp New in version 3.15. .sp This property controls where the Swift diagnostics are serialized. .SS SYMBOLIC .sp Is this just a name for a rule. .sp If \fBSYMBOLIC\fP (boolean) is set to \fBTrue\fP the build system will be informed that the source file is not actually created on disk but instead used as a symbolic name for a build rule. .SS UNITY_GROUP .sp New in version 3.18. .sp This property controls which \fIbucket\fP the source will be part of when the \fI\%UNITY_BUILD_MODE\fP is set to \fBGROUP\fP\&. .SS VS_COPY_TO_OUT_DIR .sp New in version 3.8. .sp Sets the \fB\fP tag for a source file in a Visual Studio project file. Valid values are \fBNever\fP, \fBAlways\fP and \fBPreserveNewest\fP\&. .SS VS_CSHARP_ .sp New in version 3.8. .sp Visual Studio and CSharp source\-file\-specific configuration. .sp Tell the \fI\%Visual Studio generators\fP to set the source file tag \fB\fP to a given value in the generated Visual Studio CSharp project. Ignored on other generators and languages. This property can be used to define dependencies between source files or set any other Visual Studio specific parameters. .sp Example usage: .INDENT 0.0 .INDENT 3.5 .sp .EX set_source_files_properties( PROPERTIES VS_CSHARP_DependentUpon VS_CSHARP_SubType \(dqForm\(dq) .EE .UNINDENT .UNINDENT .SS VS_DEPLOYMENT_CONTENT .sp New in version 3.1. .sp Mark a source file as content for deployment with a Windows Phone or Windows Store application when built with a \fI\%Visual Studio generators\fP\&. The value must evaluate to either \fB1\fP or \fB0\fP and may use \fI\%generator expressions\fP to make the choice based on the build configuration. The \fB\&.vcxproj\fP file entry for the source file will be marked either \fBDeploymentContent\fP or \fBExcludedFromBuild\fP for values \fB1\fP and \fB0\fP, respectively. .SS VS_DEPLOYMENT_LOCATION .sp New in version 3.1. .sp Specifies the deployment location for a content source file with a Windows Phone or Windows Store application when built with a \fI\%Visual Studio generators\fP\&. This property is only applicable when using \fI\%VS_DEPLOYMENT_CONTENT\fP\&. The value represent the path relative to the app package and applies to all configurations. .SS VS_INCLUDE_IN_VSIX .sp New in version 3.8. .sp Boolean property to specify if the file should be included within a VSIX (Visual Studio Integration Extension) extension package. This is needed for development of Visual Studio extensions. .SS VS_RESOURCE_GENERATOR .sp New in version 3.8. .sp This property allows to specify the resource generator to be used on this file. It defaults to \fBPublicResXFileCodeGenerator\fP if not set. .sp This property only applies to C# projects. .SS VS_SETTINGS .sp New in version 3.18. .sp Set any item metadata on a file. .sp New in version 3.22: This property is honored for all source file types. Previously it worked only for non\-built files. .sp Takes a list of \fBKey=Value\fP pairs. Tells the Visual Studio generator to set \fBKey\fP to \fBValue\fP as item metadata on the file. .sp For example: .INDENT 0.0 .INDENT 3.5 .sp .EX set_property(SOURCE file.hlsl PROPERTY VS_SETTINGS \(dqKey=Value\(dq \(dqKey2=Value2\(dq) .EE .UNINDENT .UNINDENT .sp will set \fBKey\fP to \fBValue\fP and \fBKey2\fP to \fBValue2\fP on the \fBfile.hlsl\fP item as metadata. .sp \fI\%Generator expressions\fP are supported. .SS VS_SHADER_DISABLE_OPTIMIZATIONS .sp New in version 3.11. .sp Disable compiler optimizations for an \fB\&.hlsl\fP source file. This adds the \fB\-Od\fP flag to the command line for the FxCompiler tool. Specify the value \fBtrue\fP for this property to disable compiler optimizations. .SS VS_SHADER_ENABLE_DEBUG .sp New in version 3.11. .sp Enable debugging information for an \fB\&.hlsl\fP source file. This adds the \fB\-Zi\fP flag to the command line for the FxCompiler tool. Specify the value \fBtrue\fP to generate debugging information for the compiled shader. .SS VS_SHADER_ENTRYPOINT .sp New in version 3.1. .sp Specifies the name of the entry point for the shader of a \fB\&.hlsl\fP source file. .SS VS_SHADER_FLAGS .sp New in version 3.2. .sp Set additional Visual Studio shader flags of a \fB\&.hlsl\fP source file. .SS VS_SHADER_MODEL .sp New in version 3.1. .sp Specifies the shader model of a \fB\&.hlsl\fP source file. Some shader types can only be used with recent shader models .SS VS_SHADER_OBJECT_FILE_NAME .sp New in version 3.12. .sp Specifies a file name for the compiled shader object file for an \fB\&.hlsl\fP source file. This adds the \fB\-Fo\fP flag to the command line for the FxCompiler tool. .SS VS_SHADER_OUTPUT_HEADER_FILE .sp New in version 3.10. .sp Set filename for output header file containing object code of a \fB\&.hlsl\fP source file. .SS VS_SHADER_TYPE .sp New in version 3.1. .sp Set the Visual Studio shader type of a \fB\&.hlsl\fP source file. .SS VS_SHADER_VARIABLE_NAME .sp New in version 3.10. .sp Set name of variable in header file containing object code of a \fB\&.hlsl\fP source file. .SS VS_TOOL_OVERRIDE .sp New in version 3.7. .sp Override the default Visual Studio tool that will be applied to the source file with a new tool not based on the extension of the file. .SS VS_XAML_TYPE .sp New in version 3.3. .sp Mark a Extensible Application Markup Language (XAML) source file as a different type than the default \fBPage\fP\&. The most common usage would be to set the default \fBApp.xaml\fP file as \fBApplicationDefinition\fP\&. .SS WRAP_EXCLUDE .sp Exclude this source file from any code wrapping techniques. .sp Some packages can wrap source files into alternate languages to provide additional functionality. .sp For example, C++ code can be wrapped into Java or Python, using SWIG. If \fBWRAP_EXCLUDE\fP is set to \fBTrue\fP, that indicates that this source file should not be wrapped. .SS XCODE_EXPLICIT_FILE_TYPE .sp New in version 3.1. .sp Set the \fI\%Xcode\fP \fBexplicitFileType\fP attribute on its reference to a source file.

The \fI\%mark_as_advanced()\fP command modifies this property. .SS HELPSTRING .sp Help associated with entry in GUIs. .sp This string summarizes the purpose of an entry to help users set it through a CMake GUI. .SS MODIFIED .sp Internal management property. Do not set or get. .sp This is an internal cache entry property managed by CMake to track interactive user modification of entries. Ignore it. .SS STRINGS .sp Enumerate possible \fBSTRING\fP entry values for GUI selection. .sp For cache entries with type \fBSTRING\fP, this enumerates a set of values. CMake GUIs may use this to provide a selection widget instead of a generic string entry field. This is for convenience only. CMake does not enforce that the value matches one of those listed. .SS TYPE .sp Widget type for entry in GUIs. .sp Cache entry values are always strings, but CMake GUIs present widgets to help users set values. The GUIs use this property as a hint to determine the widget type. Valid \fBTYPE\fP values are: .INDENT 0.0 .INDENT 3.5 .sp .EX BOOL = Boolean ON/OFF value. PATH = Path to a directory.

See CMake Policy \fI\%CMP0043\fP\&. .sp Per\-configuration preprocessor definitions on a target. .sp This is the configuration\-specific version of \fI\%COMPILE_DEFINITIONS\fP where \fB\fP is an upper\-case name (ex. \fBCOMPILE_DEFINITIONS_DEBUG\fP). .sp Contents of \fBCOMPILE_DEFINITIONS_\fP may use \(dqgenerator expressions\(dq with the syntax \fB$<...>\fP\&. See the \fI\%cmake\-generator\-expressions(7)\fP manual for available expressions. See the \fI\%cmake\-buildsystem(7)\fP manual for more on defining buildsystem properties. .sp Generator expressions should be preferred instead of setting this property. .SS IMPORTED_NO_SYSTEM .sp New in version 3.23. .sp Deprecated since version 3.25: \fBIMPORTED_NO_SYSTEM\fP is deprecated. Please use the following alternatives instead: .INDENT 0.0 .IP \(bu 2 Set \fI\%SYSTEM\fP to false if you don\(aqt want a target\(aqs include directories to be treated as system directories when compiling consumers. .IP \(bu 2 Set \fI\%EXPORT_NO_SYSTEM\fP to true if you don\(aqt want the include directories of the imported target generated by \fI\%install(EXPORT)\fP and \fI\%export()\fP commands to be treated as system directories when compiling consumers. .UNINDENT .sp Setting \fBIMPORTED_NO_SYSTEM\fP to true on an \fI\%imported target\fP specifies that it is not a system target. This has the following effects: .INDENT 0.0 .IP \(bu 2 Entries of \fI\%INTERFACE_INCLUDE_DIRECTORIES\fP are not treated as system include directories when compiling consumers (regardless of the value of the consumed target\(aqs \fI\%SYSTEM\fP property), as they would be by default. Entries of \fI\%INTERFACE_SYSTEM_INCLUDE_DIRECTORIES\fP are not affected, and will always be treated as system include directories. .IP \(bu 2 On Apple platforms, when the target is a framework, it will not be treated as system. .UNINDENT .sp This property can also be enabled on a non\-imported target. Doing so does not affect the build system, but does tell the \fI\%install(EXPORT)\fP and \fI\%export()\fP commands to enable it on the imported targets they generate. .sp See the \fI\%NO_SYSTEM_FROM_IMPORTED\fP target property to set this behavior on the target \fIconsuming\fP the include directories rather than the one \fIproviding\fP them. .SS IOS_INSTALL_COMBINED .sp New in version 3.5. .sp Deprecated since version 3.28: \fI\%IOS_INSTALL_COMBINED\fP was designed to make universal binaries containing iOS/arm* device code paired with iOS Simulator/x86_64 code (or similar for other Apple embedded platforms). Universal binaries can only differentiate code based on CPU type, so this only made sense before the days of arm64 macOS machines (i.e. iOS Simulator/arm64). Apple now recommends xcframeworks, which contain multiple binaries for different platforms, for this use case. .sp Build a combined (device and simulator) target when installing. .sp When this property is set to false, which is the default, then it will either be built with the device SDK or the simulator SDK depending on the SDK set. But if this property is set to true then the target will at install time also be built for the other SDK and combined into one library. .sp \fBNOTE:\fP .INDENT 0.0 .INDENT 3.5 If a selected architecture is available for both device SDK and simulator SDK it will be built for the SDK selected by \fI\%CMAKE_OSX_SYSROOT\fP and removed from the other SDK. .UNINDENT .UNINDENT .sp This feature requires at least Xcode version 6. .SS POST_INSTALL_SCRIPT .sp Deprecated install support. .sp The \fI\%PRE_INSTALL_SCRIPT\fP and \fBPOST_INSTALL_SCRIPT\fP properties are the old way to specify CMake scripts to run before and after installing a target. They are used only when the old \fBINSTALL_TARGETS\fP command is used to install the target. Use the \fI\%install()\fP command instead. .SS PRE_INSTALL_SCRIPT .sp Deprecated install support. .sp The \fBPRE_INSTALL_SCRIPT\fP and \fI\%POST_INSTALL_SCRIPT\fP properties are the old way to specify CMake scripts to run before and after installing a target. They are used only when the old \fBINSTALL_TARGETS\fP command is used to install the target. Use the \fI\%install()\fP command instead. .SS VS_WINRT_EXTENSIONS .sp Deprecated. Use \fI\%VS_WINRT_COMPONENT\fP instead. This property was an experimental partial implementation of that one. .SH DEPRECATED PROPERTIES ON SOURCE FILES .SS COMPILE_DEFINITIONS_ .sp Ignored. See CMake Policy \fI\%CMP0043\fP\&. .sp Per\-configuration preprocessor definitions on a source file. .sp This is the configuration\-specific version of \fI\%COMPILE_DEFINITIONS\fP\&. Note that \fI\%Xcode\fP does not support per\-configuration source file flags so this property will be ignored by the \fI\%Xcode\fP generator. .SH COPYRIGHT 2000-2024 Kitware, Inc. and Contributors .\" Generated by docutils manpage writer. .
