.ft C
FIXUP_BUNDLE(<app> <libs> <dirs>)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
Fix up a bundle in\-place and make it standalone, such that it can be
drag\-n\-drop copied to another machine and run on that machine as long
as all of the system libraries are compatible.
.sp
If you pass plugins to fixup_bundle as the libs parameter, you should
install them or copy them into the bundle before calling fixup_bundle.
The "libs" parameter is a list of libraries that must be fixed up, but
that cannot be determined by otool output analysis.  (i.e., plugins)
.sp
Gather all the keys for all the executables and libraries in a bundle,
and then, for each key, copy each prerequisite into the bundle.  Then
fix each one up according to its own list of prerequisites.
.sp
Then clear all the keys and call verify_app on the final bundle to
ensure that it is truly standalone.
.sp
As an optional parameter (IGNORE_ITEM) a list of file names can be passed,
which are then ignored (e.g. IGNORE_ITEM "vcredist_x86.exe;vcredist_x64.exe")

.sp
Given a file (item) name, generate a key that should be unique
considering the set of libraries that need copying or fixing up to
make a bundle standalone.  This is essentially the file name including
extension with "." replaced by "_"
.sp
This key is used as a prefix for CMake variables so that we can
associate a set of variables with a given item based on its key.

.UNINDENT
.UNINDENT
.sp
Loop over all the executable and library files within the bundle (and
given as extra <libs>) and accumulate a list of keys representing
them.  Set values associated with each key such that we can loop over
all of them and copy prerequisite libs into the bundle and then do
appropriate install_name_tool fixups.
.sp
As an optional parameter (IGNORE_ITEM) a list of file names can be passed,
which are then ignored (e.g. IGNORE_ITEM "vcredist_x86.exe;vcredist_x64.exe")

COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)
.ft P
.fi
.UNINDENT
.UNINDENT

Copy a resolved item into the bundle if necessary.  Copy is not
necessary if the resolved_item is "the same as" the
resolved_embedded_item.

.fi
.UNINDENT
.UNINDENT
.sp
Copy a resolved framework into the bundle if necessary.  Copy is not
necessary if the resolved_item is "the same as" the
resolved_embedded_item.
.sp
By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set.  If you want
full frameworks embedded in your bundles, set
BU_COPY_FULL_FRAMEWORK_CONTENTS to ON before calling fixup_bundle.  By
default, COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework
dylib itself plus the framework Resources directory.

.sp
.nf
.ft C
FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)
.ft P

.UNINDENT
.UNINDENT
.sp
Get the direct/non\-system prerequisites of the resolved embedded item.
For each prerequisite, change the way it is referenced to the value of
the _EMBEDDED_ITEM keyed variable for that prerequisite.  (Most likely
changing to an "@executable_path" style reference.)
.sp
This function requires that the resolved_embedded_item be "inside" the
bundle already.  In other words, if you pass plugins to fixup_bundle
as the libs parameter, you should install them or copy them into the
bundle before calling fixup_bundle.  The "libs" parameter is a list of
libraries that must be fixed up, but that cannot be determined by
otool output analysis.  (i.e., plugins)
.sp
Also, change the id of the item being fixed up to its own
_EMBEDDED_ITEM value.
.sp
Accumulate changes in a local variable and make \fIone\fP call to
install_name_tool at the end of the function with all the changes at
once.
.sp
If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be
marked writable before install_name_tool tries to change them.

Verifies that the sum of all prerequisites of all files inside the
bundle are contained within the bundle or are "system" libraries,
presumed to exist everywhere.
.sp

If the header files define the symbol as a macro it is considered
available and assumed to work.  If the header files declare the symbol
as a function or variable then the symbol must also be available for

Both \fBHAVE_${VARIABLE}\fP and \fB${VARIABLE}\fP will be created as internal

.sp
Furthermore, the variable "${VARIABLE}_CODE" holds C preprocessor code
to define the macro "${VARIABLE}" to the size of the type, or leave
the macro undefined if the type does not exist.
.sp
The variable "${VARIABLE}" may be "0" when CMAKE_OSX_ARCHITECTURES has
multiple architectures for building OS X universal binaries.  This
indicates that the type size varies across architectures.  In this
case "${VARIABLE}_CODE" contains C preprocessor tests mapping from
each architecture macro to the corresponding type size.  The list of
architecture macros is stored in "${VARIABLE}_KEYS", and the value for
each key is stored in "${VARIABLE}\-${KEY}".
.sp
If the BUILTIN_TYPES_ONLY option is not given, the macro checks for
headers <sys/types.h>, <stdint.h>, and <stddef.h>, and saves results
in HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H.  The type size
check automatically includes the available headers, thus supporting
checks of types defined in the headers.
.sp
If LANGUAGE is set, the specified compiler will be used to perform the
check. Acceptable values are C and CXX
.sp
Despite the name of the macro you may use it to check the size of more
complex expressions, too.  To check e.g.  for the size of a struct
member you can do something like this:

.SS CMakeAddFortranSubdirectory
.sp
Use MinGW gfortran from VS if a fortran compiler is not found.
.sp
The \(aqadd_fortran_subdirectory\(aq function adds a subdirectory to a
project that contains a fortran only sub\-project.  The module will
check the current compiler and see if it can support fortran.  If no
fortran compiler is found and the compiler is MSVC, then this module
will find the MinGW gfortran.  It will then use an external project to
build with the MinGW tools.  It will also create imported targets for
the libraries created.  This will only work if the fortran code is
built into a dll, so BUILD_SHARED_LIBS is turned on in the project.
In addition the CMAKE_GNUtoMS option is set to on, so that the MS .lib
files are created.  Usage is as follows:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
cmake_add_fortran_subdirectory(
 <subdir>                # name of subdirectory

 ARCHIVE_DIR <dir>       # dir where project places .lib files
 RUNTIME_DIR <dir>       # dir where project places .dll files
 LIBRARIES <lib>...      # names of library targets to import
 LINK_LIBRARIES          # link interface libraries for LIBRARIES
  [LINK_LIBS <lib> <dep>...]...
 CMAKE_COMMAND_LINE ...  # extra command line flags to pass to cmake

Relative paths in ARCHIVE_DIR and RUNTIME_DIR are interpreted with

.SS CMakeDependentOption
.sp
Macro to provide an option dependent on other options.
.sp
This macro presents an option to the user only if a set of other
conditions are true.  When the option is not presented a default value
is used, but any value set by the user is preserved for when the
option is presented again.  Example invocation:
.INDENT 0.0

.fi
.UNINDENT
.UNINDENT
.sp
If USE_BAR is true and USE_ZOT is false, this provides an option
called USE_FOO that defaults to ON.  Otherwise, it sets USE_FOO to
OFF.  If the status of USE_BAR or USE_ZOT ever changes, any value for
the USE_FOO option is saved so that when the option is re\-enabled it
retains its old value.

The macros provided by this module were once intended for use by
cross\-compiling toolchain files when CMake was not able to automatically
detect the compiler identification.  Since the introduction of this module,
CMake\(aqs compiler identification capabilities have improved and can now be
taught to recognize any compiler.  Furthermore, the suite of information
CMake detects from a compiler is now too extensive to be provided by
toolchain files using these macros.
.sp
One common use case for this module was to skip CMake\(aqs checks for a
working compiler when using a cross\-compiler that cannot link binaries
without special flags or custom linker scripts.  This case is now supported
by setting the \fBCMAKE_TRY_COMPILE_TARGET_TYPE\fP variable in the
toolchain file instead.

determine the \fBinstalledPrefix\fP is correct, and if \fBCONFIG_INSTALL_DIR\fP
contains a relative path, which in general cannot be guaranteed.  This has the
effect that the resulting \fBFooConfig.cmake\fP file would work poorly under
Windows and OSX, where users are used to choose the install location of a
binary package at install time, independent from how
\fBCMAKE_INSTALL_PREFIX\fP was set at build/cmake time.
.sp
Using \fBconfigure_package_config_file\fP helps.  If used correctly, it makes
the resulting \fBFooConfig.cmake\fP file relocatable.  Usage:
.INDENT 0.0
.IP 1. 3
write a \fBFooConfig.cmake.in\fP file as you are used to
.IP 2. 3
insert a line containing only the string \fB@PACKAGE_INIT@\fP
.IP 3. 3
instead of \fBset(FOO_DIR "@SOME_INSTALL_DIR@")\fP, use
\fBset(FOO_DIR "@PACKAGE_SOME_INSTALL_DIR@")\fP (this must be after the
\fB@PACKAGE_INIT@\fP line)
.IP 4. 3
instead of using the normal \fBconfigure_file()\fP, use
\fBconfigure_package_config_file()\fP
.UNINDENT
.sp
The \fB<input>\fP and \fB<output>\fP arguments are the input and output file, the
same way as in \fBconfigure_file()\fP\&.
.sp
The \fB<path>\fP given to \fBINSTALL_DESTINATION\fP must be the destination where
the \fBFooConfig.cmake\fP file will be installed to.  This path can either be
absolute, or relative to the \fBINSTALL_PREFIX\fP path.
.sp
The variables \fB<var1>\fP to \fB<varN>\fP given as \fBPATH_VARS\fP are the
variables which contain install destinations.  For each of them the macro will
create a helper variable \fBPACKAGE_<var...>\fP\&.  These helper variables must be
used in the \fBFooConfig.cmake.in\fP file for setting the installed location.
They are calculated by \fBconfigure_package_config_file\fP so that they are
always relative to the installed location of the package.  This works both for
relative and also for absolute locations.  For absolute locations it works
only if the absolute location is a subdirectory of \fBINSTALL_PREFIX\fP\&.
.sp
If the \fBINSTALL_PREFIX\fP argument is passed, this is used as base path to
calculate all the relative paths.  The \fB<path>\fP argument must be an absolute
path.  If this argument is not passed, the \fBCMAKE_INSTALL_PREFIX\fP
variable will be used instead.  The default value is good when generating a
FooConfig.cmake file to use your package from the install tree.  When
generating a FooConfig.cmake file to use your package from the build tree this
option should be used.
.sp
By default \fBconfigure_package_config_file\fP also generates two helper macros,
\fBset_and_check()\fP and \fBcheck_required_components()\fP into the
\fBFooConfig.cmake\fP file.
.sp
\fBset_and_check()\fP should be used instead of the normal \fBset()\fP command for
setting directories and file locations.  Additionally to setting the variable
it also checks that the referenced file or directory actually exists and fails
with a \fBFATAL_ERROR\fP otherwise.  This makes sure that the created
\fBFooConfig.cmake\fP file does not contain wrong references.
When using the \fBNO_SET_AND_CHECK_MACRO\fP, this macro is not generated
into the \fBFooConfig.cmake\fP file.
.sp
\fBcheck_required_components(<package_name>)\fP should be called at the end of
the \fBFooConfig.cmake\fP file if the package supports components.  This macro
checks whether all requested, non\-optional components have been found, and if
this is not the case, sets the \fBFoo_FOUND\fP variable to \fBFALSE\fP, so that
the package is considered to be not found.  It does that by testing the
\fBFoo_<Component>_FOUND\fP variables for all requested required components.
When using the \fBNO_CHECK_REQUIRED_COMPONENTS_MACRO\fP option, this macro is
not generated into the \fBFooConfig.cmake\fP file.
.sp
For an example see below the documentation for
\fBwrite_basic_package_version_file()\fP\&.

\fB<filename>\fP is the output filename, it should be in the build tree.
\fB<major.minor.patch>\fP is the version number of the project to be installed.
.sp
If no \fBVERSION\fP is given, the \fBPROJECT_VERSION\fP variable is used.
If this hasn\(aqt been set, it errors out.
.sp
The \fBCOMPATIBILITY\fP mode \fBAnyNewerVersion\fP means that the installed
package version will be considered compatible if it is newer or exactly the
same as the requested version.  This mode should be used for packages which
are fully backward compatible, also across major versions.
If \fBSameMajorVersion\fP is used instead, then the behaviour differs from
\fBAnyNewerVersion\fP in that the major version number must be the same as
requested, e.g.  version 2.0 will not be considered compatible if 1.0 is
requested.  This mode should be used for packages which guarantee backward
compatibility within the same major version.
If \fBExactVersion\fP is used, then the package is only considered compatible if
the requested version matches exactly its own version number (not considering
the tweak version).  For example, version 1.2.3 of a package is only
considered compatible to requested version 1.2.3.  This mode is for packages
without compatibility guarantees.
If your project has more elaborated version matching rules, you will need to
write your own custom \fBConfigVersion.cmake\fP file instead of using this
macro.
.sp
Internally, this macro executes \fBconfigure_file()\fP to create the
resulting version file.  Depending on the \fBCOMPATIBLITY\fP, either the file
\fBBasicConfigVersion\-SameMajorVersion.cmake.in\fP or
\fBBasicConfigVersion\-AnyNewerVersion.cmake.in\fP is used.  Please note that
these two files are internal to CMake and you should not call
\fBconfigure_file()\fP on them yourself, but they can be used as starting
point to create more sophisticted custom \fBConfigVersion.cmake\fP files.

.SS Variables concerning CPack Components
.sp
The CPackComponent module is the module which handles the component
part of CPack.  See CPack module for general information about CPack.
.sp
For certain kinds of binary installers (including the graphical
installers on Mac OS X and Windows), CPack generates installers that
allow users to select individual application components to install.
The contents of each of the components are identified by the COMPONENT
argument of CMake\(aqs INSTALL command.  These components can be
annotated with user\-friendly names and descriptions, inter\-component
dependencies, etc., and grouped in various ways to customize the
resulting installer.  See the cpack_add_* commands, described below,
for more information about component\-specific installations.
.sp
Component\-specific installation allows users to select specific sets
of components to install during the install process.  Installation
components are identified by the COMPONENT argument of CMake\(aqs INSTALL
commands, and should be further described by the following CPack
commands:
.INDENT 0.0
.TP
.B CPACK_COMPONENTS_ALL
The list of component to install.
.sp
The default value of this variable is computed by CPack and contains all
components defined by the project.  The user may set it to only include the
specified components.
.UNINDENT
.INDENT 0.0
.TP
.B CPACK_<GENNAME>_COMPONENT_INSTALL
Enable/Disable component install for CPack generator <GENNAME>.
.sp
Each CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has a legacy
default behavior.  e.g.  RPM builds monolithic whereas NSIS builds
component.  One can change the default behavior by setting this variable to
0/1 or OFF/ON.
.UNINDENT
.INDENT 0.0
.TP
.B CPACK_COMPONENTS_GROUPING
Specify how components are grouped for multi\-package component\-aware CPack
generators.
.sp
Some generators like RPM or ARCHIVE family (TGZ, ZIP, ...) generates
several packages files when asked for component packaging.  They group
the component differently depending on the value of this variable:
.INDENT 7.0
.IP \(bu 2
ONE_PER_GROUP (default): creates one package file per component group
.IP \(bu 2
ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component
.IP \(bu 2
IGNORE : creates one package per component, i.e. IGNORE component group

.sp
DESCRIPTION is an extended description of the component, used in
graphical installers to give the user additional information about the
component.  Descriptions can span multiple lines using \fB\en\fP as the
line separator.  Typically, these descriptions should be no more than
a few lines long.
.sp
HIDDEN indicates that this component will be hidden in the graphical
installer, so that the user cannot directly change whether it is
installed or not.
.sp
REQUIRED indicates that this component is required, and therefore will
always be installed.  It will be visible in the graphical installer,
but it cannot be unselected.  (Typically, required components are
shown greyed out).
.sp
DISABLED indicates that this component should be disabled (unselected)
by default.  The user is free to select this component for
installation, unless it is also HIDDEN.
.sp
DEPENDS lists the components on which this component depends.  If this
component is selected, then each of the components listed must also be
selected.  The dependency information is encoded within the installer
itself, so that users cannot install inconsistent sets of components.
.sp
GROUP names the component group of which this component is a part.  If
not provided, the component will be a standalone component, not part
of any component group.  Component groups are described with the
cpack_add_component_group command, detailed below.

The cpack_configure_downloads command configures installation\-time
downloads of selected components.  For each downloadable component,
CPack will create an archive containing the contents of that
component, which should be uploaded to the given site.  When the user
selects that component for installation, the installer will download
and extract the component in place.  This feature is useful for
creating small installers that only download the requested components,
saving bandwidth.  Additionally, the installers are small enough that
they will be installed as part of the normal installation process, and
the "Change" button in Windows Add/Remove Programs control panel will
allow one to add or remove parts of the application after the original
installation.  On Windows, the downloaded\-components functionality

.SS Variables specific to CPack Debian (DEB) generator
.sp
CPackDeb may be used to create Deb package using \fBCPack\fP\&.
CPackDeb is a \fBCPack\fP generator thus it uses the \fBCPACK_XXX\fP
variables used by \fBCPack\fP\&.
.sp
CPackDeb generator should work on any Linux host but it will produce
better deb package when Debian specific tools \fBdpkg\-xxx\fP are usable on
the build system.
.sp
CPackDeb has specific features which are controlled by the specifics
\fBCPACK_DEBIAN_XXX\fP variables.
.sp
\fBCPACK_DEBIAN_<COMPONENT>_XXXX\fP variables may be used in order to have
\fBcomponent\fP specific values.  Note however that \fB<COMPONENT>\fP refers to

.SS CPackIFW
.sp
This module looks for the location of the command line utilities supplied
with the Qt Installer Framework (\fI\%QtIFW\fP).
.sp
The module also defines several commands to control the behavior of the
CPack \fBIFW\fP generator.
.SS Overview
.sp
CPack \fBIFW\fP generator helps you to create online and offline
binary cross\-platform installers with a graphical user interface.
.sp
CPack IFW generator prepares project installation and generates configuration
and meta information for \fI\%QtIFW\fP tools.
.sp
The \fI\%QtIFW\fP provides a set of tools and utilities to create
installers for the supported desktop Qt platforms: Linux, Microsoft Windows,
and Mac OS X.
.sp
You should also install \fI\%QtIFW\fP to use CPack \fBIFW\fP generator.
If you don\(aqt use a default path for the installation, please set

.sp
By default CPack IFW generator makes offline installer. This means that all
components will be packaged into a binary file.
.sp
To make a component downloaded, you must set the \fBDOWNLOADED\fP option in
\fBcpack_add_component()\fP\&.
.sp
Then you would use the command \fBcpack_configure_downloads()\fP\&.
If you set \fBALL\fP option all components will be downloaded.
.sp
You also can use command \fBcpack_ifw_add_repository()\fP and
variable \fBCPACK_IFW_DOWNLOAD_ALL\fP for more specific configuration.
.sp
CPack IFW generator creates "repository" dir in current binary dir. You
would copy content of this dir to specified \fBsite\fP (\fBurl\fP).

.TP
.B CPACK_OSX_PACKAGE_VERSION
The version of Mac OS X that the resulting PackageMaker archive should be

features. For example, CPack can only build component\-based installers for
Mac OS X 10.4 or newer, and can only build installers that download
component son\-the\-fly for Mac OS X 10.5 or newer. If left blank, this value
will be set to the minimum version of Mac OS X that supports the requested
features. Set this variable to some value (e.g., 10.4) only if you want to
guarantee that your installer will work on that version of Mac OS X, and
don\(aqt mind missing extra features available in the installer shipping with
later versions of Mac OS X.

.SS CPackRPM

.sp
CPackRPM has specific features which are controlled by the specifics
\fBCPACK_RPM_XXX\fP variables.
.sp
\fBCPACK_RPM_<COMPONENT>_XXXX\fP variables may be used in order to have
\fBcomponent\fP specific values.  Note however that \fB<COMPONENT>\fP refers to the
\fBgrouping name\fP written in upper case. It may be either a component name or
a component GROUP name. Usually those variables correspond to RPM spec file
entities. One may find information about spec files here
\fI\%http://www.rpm.org/wiki/Docs\fP
.sp
\fBNOTE:\fP
.INDENT 0.0
.INDENT 3.5
\fI<COMPONENT>\fP part of variables is preferred to be in upper case (for e.g. if
component is named \fIfoo\fP then use \fICPACK_RPM_FOO_XXXX\fP variable name format)
as is with other \fICPACK_<COMPONENT>_XXXX\fP variables.
For the purposes of back compatibility (CMake/CPack version 3.5 and lower)
support for same cased component (e.g. \fIfOo\fP would be used as
\fICPACK_RPM_fOo_XXXX\fP) is still supported for variables defined in older
versions of CMake/CPack but is not guaranteed for variables that
will be added in the future. For the sake of back compatibility same cased
component variables also override upper cased versions where both are
present.

.SS Packaging of Symbolic Links
.sp
CPackRPM supports packaging of symbolic links:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
execute_process(COMMAND ${CMAKE_COMMAND}
  \-E create_symlink <relative_path_location> <symlink_name>)
install(FILES ${CMAKE_CURRENT_BINARY_DIR}/<symlink_name>
  DESTINATION <symlink_location> COMPONENT libraries)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
Symbolic links will be optimized (paths will be shortened if possible)
before being added to the package or if multiple relocation paths are
detected, a post install symlink relocation script will be generated.
.sp
Symbolic links may point to locations that are not packaged by the same
package (either a different component or even not packaged at all) but
those locations will be treated as if they were a part of the package
while determining if symlink should be either created or present in a
post install script \- depending on relocation paths.
.sp
Symbolic links that point to locations outside packaging path produce a
warning and are treated as non relocatable permanent symbolic links.
.sp
Currently there are a few limitations though:
.INDENT 0.0
.IP \(bu 2
For component based packaging component interdependency is not checked
when processing symbolic links. Symbolic links pointing to content of
a different component are treated the same way as if pointing to location
that will not be packaged.
.IP \(bu 2
Symbolic links pointing to a location through one or more intermediate
symbolic links will not be handled differently \- if the intermediate
symbolic link(s) is also on a relocatable path, relocating it during
package installation may cause initial symbolic link to point to an
invalid location.

.SS CPack
.sp
Build binary and source package installers.
.SS Variables common to all CPack generators
.sp
The
CPack module generates binary and source installers in a variety of
formats using the cpack program.  Inclusion of the CPack module adds
two new targets to the resulting makefiles, package and
package_source, which build the binary and source installers,
respectively.  The generated binary installers contain everything
installed via CMake\(aqs INSTALL command (and the deprecated
INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).
.sp
For certain kinds of binary installers (including the graphical
installers on Mac OS X and Windows), CPack generates installers that
allow users to select individual application components to install.
See CPackComponent module for that.
.sp
The CPACK_GENERATOR variable has different meanings in different
contexts.  In your CMakeLists.txt file, CPACK_GENERATOR is a \fIlist of
generators\fP: when run with no other arguments, CPack will iterate over
that list and produce one package for each generator.  In a
CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERATOR is a \fIstring naming
a single generator\fP\&.  If you need per\-cpack\- generator logic to
control \fIother\fP cpack settings, then you need a
CPACK_PROJECT_CONFIG_FILE.
.sp
The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE.
See the top level file CMakeCPackOptions.cmake.in for an example.
.sp
If set, the CPACK_PROJECT_CONFIG_FILE is included automatically on a
per\-generator basis.  It only need contain overrides.
.sp
Here\(aqs how it works:
.INDENT 0.0
.IP \(bu 2
cpack runs
.IP \(bu 2
it includes CPackConfig.cmake
.IP \(bu 2
it iterates over the generators listed in that file\(aqs
CPACK_GENERATOR list variable (unless told to use just a
specific one via \-G on the command line...)
.IP \(bu 2
foreach generator, it then
.INDENT 2.0
.IP \(bu 2
sets CPACK_GENERATOR to the one currently being iterated
.IP \(bu 2
includes the CPACK_PROJECT_CONFIG_FILE
.IP \(bu 2
produces the package for that generator
.UNINDENT
.UNINDENT
.sp
This is the key: For each generator listed in CPACK_GENERATOR in
CPackConfig.cmake, cpack will \fIreset\fP CPACK_GENERATOR internally to
\fIthe one currently being used\fP and then include the
CPACK_PROJECT_CONFIG_FILE.
.sp
Before including this CPack module in your CMakeLists.txt file, there
are a variety of variables that can be set to customize the resulting
installers.  The most commonly\-used variables are:
.INDENT 0.0

be defined in CPack config file or from the cpack command line option
"\-B". If set the command line option override the value found in the
config file.

.B CPACK_RESOURCE_FILE_LICENSE
License to be embedded in the installer. It will typically be displayed
to the user by the produced installer (often with an explicit "Accept"
button, for graphical installers) prior to installation. This license
file is NOT added to installed file but is used by some CPack generators
like NSIS. If you want to install a license file (may be the same as this
one) along with your project you must add an appropriate CMake INSTALL
command in your CMakeLists.txt.

.SS CTestScriptMode
.sp
This file is read by ctest in script mode (\-S)
.SS CTestUseLaunchers
.sp
Set the RULE_LAUNCH_* global properties when CTEST_USE_LAUNCHERS is on.
.sp
CTestUseLaunchers is automatically included when you include(CTest).
However, it is split out into its own module file so projects can use
the CTEST_USE_LAUNCHERS functionality independently.
.sp
To use launchers, set CTEST_USE_LAUNCHERS to ON in a ctest \-S
dashboard script, and then also set it in the cache of the configured
project.  Both cmake and ctest need to know the value of it for the
launchers to work properly.  CMake needs to know in order to generate
proper build rules, and ctest, in order to produce the proper error
and warning analysis.
.sp
For convenience, you may set the ENV variable
CTEST_USE_LAUNCHERS_DEFAULT in your ctest \-S script, too.  Then, as
long as your CMakeLists uses include(CTest) or
include(CTestUseLaunchers), it will use the value of the ENV variable
to initialize a CTEST_USE_LAUNCHERS cache variable.  This cache
variable initialization only occurs if CTEST_USE_LAUNCHERS is not
already defined.
.SS Dart
.sp
Configure a project for testing with CTest or old Dart Tcl Client
.sp
This file is the backwards\-compatibility version of the CTest module.
It supports using the old Dart 1 Tcl client for driving dashboard
submissions as well as testing with CTest.  This module should be
included in the CMakeLists.txt file at the top of a project.  Typical
usage:

.SS ExternalData
.sp
Manage data files stored outside source tree
.SS Introduction
.sp
Use this module to unambiguously reference data files stored outside
the source tree and fetch them at build time from arbitrary local and
remote content\-addressed locations.  Functions provided by this module
recognize arguments with the syntax \fBDATA{<name>}\fP as references to
external data, replace them with full paths to local copies of those
data, and create build rules to fetch and update the local copies.
.sp
For example:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
include(ExternalData)
set(ExternalData_URL_TEMPLATES "file:///local/%(algo)/%(hash)"
                               "file:////host/share/%(algo)/%(hash)"
                               "http://data.org/%(algo)/%(hash)")
ExternalData_Add_Test(MyData
  NAME MyTest
  COMMAND MyExe DATA{MyInput.png}
  )
ExternalData_Add_Target(MyData)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
When test \fBMyTest\fP runs the \fBDATA{MyInput.png}\fP argument will be
replaced by the full path to a real instance of the data file
\fBMyInput.png\fP on disk.  If the source tree contains a content link
such as \fBMyInput.png.md5\fP then the \fBMyData\fP target creates a real
\fBMyInput.png\fP in the build tree.

.UNINDENT
.UNINDENT
.sp
It creates custom commands in the target as necessary to make data
files available for each \fBDATA{}\fP reference previously evaluated by
other functions provided by this module.
Data files may be fetched from one of the URL templates specified in
the \fBExternalData_URL_TEMPLATES\fP variable, or may be found locally
in one of the paths specified in the \fBExternalData_OBJECT_STORES\fP
variable.
.UNINDENT
.SS Module Variables
.sp
The following variables configure behavior.  They should be set before
calling any of the functions provided by this module.
.INDENT 0.0
.TP
.B ExternalData_BINARY_ROOT
The \fBExternalData_BINARY_ROOT\fP variable may be set to the directory to
hold the real data files named by expanded \fBDATA{}\fP references.  The
default is \fBCMAKE_BINARY_DIR\fP\&.  The directory layout will mirror that of
content links under \fBExternalData_SOURCE_ROOT\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B ExternalData_CUSTOM_SCRIPT_<key>
Specify a full path to a \fB\&.cmake\fP custom fetch script identified by
\fB<key>\fP in entries of the \fBExternalData_URL_TEMPLATES\fP list.
See \fI\%Custom Fetch Scripts\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B ExternalData_LINK_CONTENT
The \fBExternalData_LINK_CONTENT\fP variable may be set to the name of a
supported hash algorithm to enable automatic conversion of real data
files referenced by the \fBDATA{}\fP syntax into content links.  For each
such \fB<file>\fP a content link named \fB<file><ext>\fP is created.  The
original file is renamed to the form \fB\&.ExternalData_<algo>_<hash>\fP to
stage it for future transmission to one of the locations in the list
of URL templates (by means outside the scope of this module).  The
data fetch rule created for the content link will use the staged
object if it cannot be found using any URL template.
.UNINDENT
.INDENT 0.0
.TP
.B ExternalData_NO_SYMLINKS
The real data files named by expanded \fBDATA{}\fP references may be made
available under \fBExternalData_BINARY_ROOT\fP using symbolic links on
some platforms.  The \fBExternalData_NO_SYMLINKS\fP variable may be set
to disable use of symbolic links and enable use of copies instead.
.UNINDENT
.INDENT 0.0
.TP
.B ExternalData_OBJECT_STORES
The \fBExternalData_OBJECT_STORES\fP variable may be set to a list of local
directories that store objects using the layout \fB<dir>/%(algo)/%(hash)\fP\&.
These directories will be searched first for a needed object.  If the
object is not available in any store then it will be fetched remotely
using the URL templates and added to the first local store listed.  If
no stores are specified the default is a location inside the build
tree.

directory containing any path named by a \fBDATA{}\fP reference.  The
default is \fBCMAKE_SOURCE_DIR\fP\&.  \fBExternalData_SOURCE_ROOT\fP and
\fBCMAKE_SOURCE_DIR\fP must refer to directories within a single source
distribution (e.g.  they come together in one tarball).
.UNINDENT

.B ExternalData_URL_ALGO_<algo>_<key>
Specify a custom URL component to be substituted for URL template
placeholders of the form \fB%(algo:<key>)\fP, where \fB<key>\fP is a
valid C identifier, when fetching an object referenced via hash
algorithm \fB<algo>\fP\&.  If not defined, the default URL component
is just \fB<algo>\fP for any \fB<key>\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B ExternalData_URL_TEMPLATES
The \fBExternalData_URL_TEMPLATES\fP may be set to provide a list of
of URL templates using the placeholders \fB%(algo)\fP and \fB%(hash)\fP
in each template.  Data fetch rules try each URL template in order
by substituting the hash algorithm name for \fB%(algo)\fP and the hash
value for \fB%(hash)\fP\&.  Alternatively one may use \fB%(algo:<key>)\fP
with \fBExternalData_URL_ALGO_<algo>_<key>\fP variables to gain more
flexibility in remote URLs.
.UNINDENT
.SS Referencing Files
.SS Referencing Single Files
.sp
The \fBDATA{}\fP syntax is literal and the \fB<name>\fP is a full or relative path
within the source tree.  The source tree must contain either a real
data file at \fB<name>\fP or a "content link" at \fB<name><ext>\fP containing a
hash of the real file using a hash algorithm corresponding to \fB<ext>\fP\&.
For example, the argument \fBDATA{img.png}\fP may be satisfied by either a
real \fBimg.png\fP file in the current source directory or a \fBimg.png.md5\fP
file containing its MD5 sum.
.SS Referencing File Series
.sp
The \fBDATA{}\fP syntax can be told to fetch a file series using the form
\fBDATA{<name>,:}\fP, where the \fB:\fP is literal.  If the source tree
contains a group of files or content links named like a series then a
reference to one member adds rules to fetch all of them.  Although all
members of a series are fetched, only the file originally named by the
\fBDATA{}\fP argument is substituted for it.  The default configuration
recognizes file series names ending with \fB#.ext\fP, \fB_#.ext\fP, \fB\&.#.ext\fP,
or \fB\-#.ext\fP where \fB#\fP is a sequence of decimal digits and \fB\&.ext\fP is
any single extension.  Configure it with a regex that parses \fB<number>\fP
and \fB<suffix>\fP parts from the end of \fB<name>\fP:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
ExternalData_SERIES_PARSE = regex of the form (<number>)(<suffix>)$
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
For more complicated cases set:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
ExternalData_SERIES_PARSE = regex with at least two () groups
ExternalData_SERIES_PARSE_PREFIX = <prefix> regex group number, if any
ExternalData_SERIES_PARSE_NUMBER = <number> regex group number
ExternalData_SERIES_PARSE_SUFFIX = <suffix> regex group number
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
Configure series number matching with a regex that matches the
\fB<number>\fP part of series members named \fB<prefix><number><suffix>\fP:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
ExternalData_SERIES_MATCH = regex matching <number> in all series members
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
Note that the \fB<suffix>\fP of a series does not include a hash\-algorithm
extension.
.SS Referencing Associated Files
.sp
The \fBDATA{}\fP syntax can alternatively match files associated with the
named file and contained in the same directory.  Associated files may
be specified by options using the syntax
\fBDATA{<name>,<opt1>,<opt2>,...}\fP\&.  Each option may specify one file by
name or specify a regular expression to match file names using the
syntax \fBREGEX:<regex>\fP\&.  For example, the arguments:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
DATA{MyData/MyInput.mhd,MyInput.img}                   # File pair
DATA{MyData/MyFrames00.png,REGEX:MyFrames[0\-9]+\e\e.png} # Series
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
will pass \fBMyInput.mha\fP and \fBMyFrames00.png\fP on the command line but
ensure that the associated files are present next to them.
.SS Referencing Directories
.sp
The \fBDATA{}\fP syntax may reference a directory using a trailing slash and
a list of associated files.  The form \fBDATA{<name>/,<opt1>,<opt2>,...}\fP
adds rules to fetch any files in the directory that match one of the
associated file options.  For example, the argument
\fBDATA{MyDataDir/,REGEX:.*}\fP will pass the full path to a \fBMyDataDir\fP
directory on the command line and ensure that the directory contains
files corresponding to every file or content link in the \fBMyDataDir\fP
source directory.  In order to match associated files in subdirectories,
specify a \fBRECURSE:\fP option, e.g. \fBDATA{MyDataDir/,RECURSE:,REGEX:.*}\fP\&.
.SS Hash Algorithms

.SS Custom Fetch Scripts
.sp
When a data file must be fetched from one of the URL templates
specified in the \fBExternalData_URL_TEMPLATES\fP variable, it is
normally downloaded using the \fBfile(DOWNLOAD)\fP command.
One may specify usage of a custom fetch script by using a URL
template of the form \fBExternalDataCustomScript://<key>/<loc>\fP\&.
The \fB<key>\fP must be a C identifier, and the \fB<loc>\fP must
contain the \fB%(algo)\fP and \fB%(hash)\fP placeholders.
A variable corresponding to the key, \fBExternalData_CUSTOM_SCRIPT_<key>\fP,
must be set to the full path to a \fB\&.cmake\fP script file.  The script
will be included to perform the actual fetch, and provided with
the following variables:
.INDENT 0.0
.TP
.B ExternalData_CUSTOM_LOCATION
When a custom fetch script is loaded, this variable is set to the
location part of the URL, which will contain the substituted hash
algorithm name and content hash value.
.UNINDENT
.INDENT 0.0

.B ExternalData_CUSTOM_FILE
When a custom fetch script is loaded, this variable is set to the
full path to a file in which the script must store the fetched
content.  The name of the file is unspecified and should not be
interpreted in any way.
.UNINDENT
.sp
The custom fetch script is expected to store fetched content in the
file or set a variable:
.INDENT 0.0

The \fB*_DIR\fP options specify directories for the project, with default
directories computed as follows.  If the \fBPREFIX\fP option is given to
\fBExternalProject_Add()\fP or the \fBEP_PREFIX\fP directory property is set,
then an external project is built and installed under the specified prefix:
.INDENT 7.0

If no \fBPREFIX\fP, \fBEP_PREFIX\fP, or \fBEP_BASE\fP is specified then the
default is to set \fBPREFIX\fP to \fB<name>\-prefix\fP\&.  Relative paths are
interpreted with respect to the build directory corresponding to the
source directory in which \fBExternalProject_Add\fP is invoked.
.sp
If \fBSOURCE_DIR\fP is explicitly set to an existing directory the project
will be built from it.  Otherwise a download step must be specified
using one of the \fBDOWNLOAD_COMMAND\fP, \fBCVS_*\fP, \fBSVN_*\fP, or \fBURL\fP
options.  The \fBURL\fP option may refer locally to a directory or source
tarball, or refer to a remote tarball (e.g. \fBhttp://.../src.tgz\fP).
.sp
If \fBUPDATE_DISCONNECTED\fP is set, the update step is not executed
automatically when building the main target. The update step can still
be added as a step target and called manually. This is useful if you
want to allow one to build the project when you are disconnected from the
network (you might still need the network for the download step).
This is disabled by default.

If \fBNO_DEPENDS\fP is set, the target will not depend on the
dependencies of the complete project. This is usually safe to use for
the download, update, and patch steps that do not require that all the
dependencies are updated and built.  Using \fBNO_DEPENDS\fP for other
of the default steps might break parallel builds, so you should avoid,
it.  For custom steps, you should consider whether or not the custom
commands requires that the dependencies are configured, built and
installed.
.sp
If \fBSTEP_TARGETS\fP or \fBINDEPENDENT_STEP_TARGETS\fP is set then
\fBExternalProject_Add_StepTargets\fP is automatically called at the end
of matching calls to \fBExternalProject_Add_Step\fP\&.  Pass
\fBSTEP_TARGETS\fP or \fBINDEPENDENT_STEP_TARGETS\fP explicitly to
individual \fBExternalProject_Add\fP calls, or implicitly to all
\fBExternalProject_Add\fP calls by setting the directory properties
\fBEP_STEP_TARGETS\fP and \fBEP_INDEPENDENT_STEP_TARGETS\fP\&.  The
\fBINDEPENDENT\fP version of the argument and of the property will call
\fBExternalProject_Add_StepTargets\fP with the \fBNO_DEPENDS\fP argument.
.sp
If \fBSTEP_TARGETS\fP and \fBINDEPENDENT_STEP_TARGETS\fP are not set,
clients may still manually call \fBExternalProject_Add_StepTargets\fP
after calling \fBExternalProject_Add\fP or \fBExternalProject_Add_Step\fP\&.
.sp
This functionality is provided to make it easy to drive the steps
independently of each other by specifying targets on build command
lines.  For example, you may be submitting to a sub\-project based
dashboard, where you want to drive the configure portion of the build,
then submit to the dashboard, followed by the build portion, followed
by tests.  If you invoke a custom target that depends on a step
halfway through the step dependency chain, then all the previous steps
will also run to ensure everything is up to date.
.sp
For example, to drive configure, build and test steps independently
for each \fBExternalProject_Add\fP call in your project, write the following
line prior to any \fBExternalProject_Add\fP calls in your \fBCMakeLists.txt\fP
file:
.INDENT 0.0
.INDENT 3.5

This function takes care to set both target and file level
dependencies, and will ensure that parallel builds will not break.

\fBExternalProject\fP\&.

Use this macro to set up information about the named package, which
can then be displayed via FEATURE_SUMMARY().  This can be done either

after the find_package() call.  The features for which information can
be set are added automatically by the find_package() command.

URL: this should be the homepage of the package, or something similar.
Ideally this is set already directly in the Find\-module.
.sp
DESCRIPTION: A short description what that package is, at most one
sentence.  Ideally this is set already directly in the Find\-module.
.sp
TYPE: What type of dependency has the using project on that package.
Default is OPTIONAL.  In this case it is a package which can be used
by the project when available at buildtime, but it also work without.
RECOMMENDED is similar to OPTIONAL, i.e.  the project will build if
the package is not present, but the functionality of the resulting
binaries will be severly limited.  If a REQUIRED package is not
available at buildtime, the project may not even build.  This can be
combined with the FATAL_ON_MISSING_REQUIRED_PACKAGES argument for
feature_summary().  Last, a RUNTIME package is a package which is
actually not used at all during the build, but which is required for
actually running the resulting binaries.  So if such a package is
missing, the project can still be built, but it may not work later on.
If set_package_properties() is called multiple times for the same
package with different TYPEs, the TYPE is only changed to higher TYPEs
( RUNTIME < OPTIONAL < RECOMMENDED < REQUIRED ), lower TYPEs are
ignored.  The TYPE property is project\-specific, so it cannot be set
by the Find\-module, but must be set in the project.
.sp
PURPOSE: This describes which features this package enables in the
project, i.e.  it tells the user what functionality he gets in the
resulting binaries.  If set_package_properties() is called multiple
times for a package, all PURPOSE properties are appended to a list of
purposes of the package in the project.  As the TYPE property, also
the PURPOSE property is project\-specific, so it cannot be set by the
Find\-module, but must be set in the project.

Implicit dependencies such as Boost::filesystem requiring
Boost::system will be automatically detected and satisfied, even
if system is not specified when using find_package and if
Boost::system is not added to target_link_libraries.  If using
Boost::thread, then Thread::Thread will also be added automatically.
.sp
It is important to note that the imported targets behave differently
than variables created by this module: multiple calls to
find_package(Boost) in the same directory or sub\-directories with
different options (e.g. static or shared) will not override the
values of the targets created by the first call.
.sp
Users may set these hints or results as cache entries.  Projects
should not read these entries directly but instead use the above
result variables.  Note that some hint names start in upper\-case
"BOOST".  One may specify these as environment variables if they are
not specified as CMake variables or cache entries.
.sp
This module first searches for the Boost header files using the above
hint variables (excluding BOOST_LIBRARYDIR) and saves the result in
Boost_INCLUDE_DIR.  Then it searches for requested component libraries
using the above hints (excluding BOOST_INCLUDEDIR and
Boost_ADDITIONAL_VERSIONS), "lib" directories near Boost_INCLUDE_DIR,
and the library name configuration settings below.  It saves the
library directories in Boost_LIBRARY_DIR_DEBUG and
Boost_LIBRARY_DIR_RELEASE and individual library
locations in Boost_<C>_LIBRARY_DEBUG and Boost_<C>_LIBRARY_RELEASE.
When one changes settings used by previous searches in the same build
tree (excluding environment variables) this module discards previous
search results affected by the changes and searches again.

CUDA_BIN_PATH before running cmake (e.g.
CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default
/usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring.  If
you change the value of CUDA_TOOLKIT_ROOT_DIR, various components that
depend on the path will be relocated.
.sp
It might be necessary to set CUDA_TOOLKIT_ROOT_DIR manually on certain
platforms, or to use a cuda runtime not installed in the default
location.  In newer versions of the toolkit the cuda library is
included with the graphics driver\- be sure that the driver version
matches what is needed by the cuda runtime version.

The following variables affect the behavior of the macros in the

CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
\-\- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
   Note that making this different from the host code when generating object
   or C files from CUDA code just won\(aqt work, because size_t gets defined by
   nvcc in the generated source.  If you compile to PTX and then load the
   file yourself, you can mix bit sizes between device and host.

CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
\-\- Set to ON if you want the custom build rule to be attached to the source
   file in Visual Studio.  Turn OFF if you add the same cuda file to multiple
   targets.

   This allows the user to build the target from the CUDA file; however, bad
   things can happen if the CUDA source file is added to multiple targets.
   When performing parallel builds it is possible for the custom build
   command to be run more than once and in parallel causing cryptic build
   errors.  VS runs the rules for every source file in the target, and a
   source can have only one rule no matter how many projects it is added to.
   When the rule is run from multiple targets race conditions can occur on
   the generated file.  Eventually everything will get built, but if the user
   is unaware of this behavior, there may be confusion.  It would be nice if
   this script could detect the reuse of source files across multiple targets
   and turn the option off for the user, but no good solution could be found.

CUDA_BUILD_CUBIN (Default OFF)
\-\- Set to ON to enable and extra compilation pass with the \-cubin option in
   Device mode. The output is parsed and register, shared memory usage is
   printed during build.

CUDA_BUILD_EMULATION (Default OFF for device mode)
\-\- Set to ON for Emulation mode. \-D_DEVICEEMU is defined for CUDA C files
   when CUDA_BUILD_EMULATION is TRUE.

CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
\-\- Set to the path you wish to have the generated files placed.  If it is
   blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
   Intermediate files will always be placed in
   CMAKE_CURRENT_BINARY_DIR/CMakeFiles.

CUDA_HOST_COMPILATION_CPP (Default ON)
\-\- Set to OFF for C compilation of host code.

CUDA_HOST_COMPILER (Default CMAKE_C_COMPILER, $(VCInstallDir)/bin for VS)
\-\- Set the host compiler to be used by nvcc.  Ignored if \-ccbin or
   \-\-compiler\-bindir is already present in the CUDA_NVCC_FLAGS or
   CUDA_NVCC_FLAGS_<CONFIG> variables.  For Visual Studio targets
   $(VCInstallDir)/bin is a special value that expands out to the path when
   the command is run from within VS.

CUDA_NVCC_FLAGS
CUDA_NVCC_FLAGS_<CONFIG>
\-\- Additional NVCC command line arguments.  NOTE: multiple arguments must be
   semi\-colon delimited (e.g. \-\-compiler\-options;\-Wall)

CUDA_PROPAGATE_HOST_FLAGS (Default ON)
\-\- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
   dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
   host compiler through nvcc\(aqs \-Xcompiler flag.  This helps make the
   generated host code match the rest of the system better.  Sometimes
   certain flags give nvcc problems, and this will help you turn the flag
   propagation off.  This does not affect the flags supplied directly to nvcc
   via CUDA_NVCC_FLAGS or through the OPTION flags specified through
   CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS.  Flags used for
   shared library compilation are not affected by this flag.

CUDA_SEPARABLE_COMPILATION (Default OFF)
\-\- If set this will enable separable compilation for all CUDA runtime object
   files.  If used outside of CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY
   (e.g. calling CUDA_WRAP_SRCS directly),
   CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME and
   CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS should be called.

CUDA_SOURCE_PROPERTY_FORMAT
\-\- If this source file property is set, it can override the format specified
   to CUDA_WRAP_SRCS (OBJ, PTX, CUBIN, or FATBIN).  If an input source file
   is not a .cu file, setting this file will cause it to be treated as a .cu
   file. See documentation for set_source_files_properties on how to set
   this property.

CUDA_USE_STATIC_CUDA_RUNTIME (Default ON)
\-\- When enabled the static version of the CUDA runtime library will be used
   in CUDA_LIBRARIES.  If the version of CUDA configured doesn\(aqt support
   this option, then it will be silently disabled.

CUDA_VERBOSE_BUILD (Default OFF)
\-\- Set to ON to see all the commands used when building the CUDA file.  When
   using a Makefile generator the value defaults to VERBOSE (run make
   VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
   always print the output.

CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
\-\- Adds the cufft library to the target (can be any target).  Handles whether
   you are in emulation mode or not.

CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
\-\- Adds the cublas library to the target (can be any target).  Handles
   whether you are in emulation mode or not.

CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ...
                     [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
\-\- Creates an executable "cuda_target" which is made up of the files
   specified.  All of the non CUDA C files are compiled using the standard
   build rules specified by CMAKE and the cuda files are compiled to object
   files using nvcc and the host compiler.  In addition CUDA_INCLUDE_DIRS is
   added automatically to include_directories().  Some standard CMake target
   calls can be used on the target after calling this macro
   (e.g. set_target_properties and target_link_libraries), but setting
   properties that adjust compilation flags will not affect code compiled by
   nvcc.  Such flags should be modified before calling CUDA_ADD_EXECUTABLE,
   CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.

CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
                  [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
\-\- Same as CUDA_ADD_EXECUTABLE except that a library is created.

CUDA_BUILD_CLEAN_TARGET()
\-\- Creates a convience target that deletes all the dependency files
   generated.  You should make clean after running this target to ensure the
   dependency files get regenerated.

CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
              [OPTIONS ...] )
\-\- Returns a list of generated files from the input source files to be used
   with ADD_LIBRARY or ADD_EXECUTABLE.

CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] )
\-\- Returns a list of PTX files generated from the input source files.

CUDA_COMPILE_FATBIN( generated_files file0 file1 ... [OPTIONS ...] )
\-\- Returns a list of FATBIN files generated from the input source files.

CUDA_COMPILE_CUBIN( generated_files file0 file1 ... [OPTIONS ...] )
\-\- Returns a list of CUBIN files generated from the input source files.

CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME( output_file_var
                                                     cuda_target
                                                     object_files )
\-\- Compute the name of the intermediate link file used for separable
   compilation.  This file name is typically passed into
   CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS.  output_file_var is produced
   based on cuda_target the list of objects files that need separable
   compilation as specified by object_files.  If the object_files list is
   empty, then output_file_var will be empty.  This function is called
   automatically for CUDA_ADD_LIBRARY and CUDA_ADD_EXECUTABLE.  Note that
   this is a function and not a macro.

CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
\-\- Sets the directories that should be passed to nvcc
   (e.g. nvcc \-Ipath0 \-Ipath1 ... ). These paths usually contain other .cu
   files.



CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS( output_file_var cuda_target
                                         nvcc_flags object_files)

\-\- Generates the link object required by separable compilation from the given
   object files.  This is called automatically for CUDA_ADD_EXECUTABLE and
   CUDA_ADD_LIBRARY, but can be called manually when using CUDA_WRAP_SRCS
   directly.  When called from CUDA_ADD_LIBRARY or CUDA_ADD_EXECUTABLE the
   nvcc_flags passed in are the same as the flags passed in via the OPTIONS
   argument.  The only nvcc flag added automatically is the bitness flag as
   specified by CUDA_64_BIT_DEVICE_CODE.  Note that this is a function
   instead of a macro.

CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
                 [STATIC | SHARED | MODULE] [OPTIONS ...] )
\-\- This is where all the magic happens.  CUDA_ADD_EXECUTABLE,
   CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
   function under the hood.

   Given the list of files (file0 file1 ... fileN) this macro generates
   custom commands that generate either PTX or linkable objects (use "PTX" or
   "OBJ" for the format argument to switch).  Files that don\(aqt end with .cu
   or have the HEADER_FILE_ONLY property are ignored.

   The arguments passed in after OPTIONS are extra command line options to
   give to nvcc.  You can also specify per configuration options by
   specifying the name of the configuration followed by the options.  General
   options must precede configuration specific options.  Not all
   configurations need to be specified, only the ones provided will be used.

      OPTIONS \-DFLAG=2 "\-DFLAG_OTHER=space in flag"
      DEBUG \-g
      RELEASE \-\-use_fast_math
      RELWITHDEBINFO \-\-use_fast_math;\-g
      MINSIZEREL \-\-use_fast_math

   For certain configurations (namely VS generating object files with
   CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
   be produced for the given cuda file.  This is because when you add the
   cuda file to Visual Studio it knows that this file produces an object file
   and will link in the resulting object file automatically.

   This script will also generate a separate cmake script that is used at
   build time to invoke nvcc.  This is for several reasons.

     1. nvcc can return negative numbers as return values which confuses
     Visual Studio into thinking that the command succeeded.  The script now
     checks the error codes and produces errors when there was a problem.

     2. nvcc has been known to not delete incomplete results when it
     encounters problems.  This confuses build systems into thinking the
     target was generated when in fact an unusable file exists.  The script
     now deletes the output files if there was an error.

     3. By putting all the options that affect the build into a file and then
     make the build rule dependent on the file, the output files will be
     regenerated when the options change.

   This script also looks at optional arguments STATIC, SHARED, or MODULE to
   determine when to target the object compilation for a shared library.
   BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
   CUDA_ADD_LIBRARY.  On some systems special flags are added for building
   objects intended for shared libraries.  A preprocessor macro,
   <target_name>_EXPORTS is defined when a shared library compilation is
   detected.

   Flags passed into add_definitions with \-D or /D are passed along to nvcc.

This module is able to find a version of DCMTK that does or does not export
a \fIDCMTKConfig.cmake\fP file. It applies a two step process:
.INDENT 0.0
.IP \(bu 2
Step 1:  Attempt to find DCMTK version providing a \fIDCMTKConfig.cmake\fP file.
.IP \(bu 2
Step 2:  If step 1 failed, rely on \fIFindDCMTK.cmake\fP to set \fIDCMTK_*\fP variables details below.

\fI\%Recent DCMTK\fP
provides a \fIDCMTKConfig.cmake\fP \fBpackage configuration file\fP\&. To exclusively use the package configuration file
(recommended when possible), pass the \fINO_MODULE\fP option to
\fBfind_package()\fP\&. For example, \fIfind_package(DCMTK NO_MODULE)\fP\&.
This requires official DCMTK snapshot \fI3.6.1_20140617\fP or newer.

Until all clients update to the more recent DCMTK, build systems will need
to support different versions of DCMTK.

ILU_LIBRARIES \-  the name of the ILU library. Again, the full path. This

ILUT_LIBRARIES \- the name of the ILUT library. Full path. This part of the

                 in applications.
IL_INCLUDE_DIR \- where to find the il.h, ilu.h and ilut.h files.
IL_FOUND \-       this is set to TRUE if all the above variables were set.
                 This will be set to false if ILU or ILUT are not found,

FLEX_FOUND \- true is flex executable is found
FLEX_EXECUTABLE \- the path to the flex executable

.UNINDENT
.UNINDENT

which creates a custom command to generate the <FlexOutput> file from
the <FlexInput> file.  If COMPILE_FLAGS option is specified, the next
parameter is added to the flex command line. If flex is configured to
output a header file, the DEFINES_FILE option may be used to specify its
name. Name is an alias used to get details of this custom command.
Indeed the macro defines the following variables:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
FLEX_${Name}_DEFINED \- true is the macro ran successfully
FLEX_${Name}_OUTPUTS \- the source file generated by the custom rule, an

.SS FindHDF5
.sp
Find HDF5, a library for reading and writing self describing array data.
.sp
This module invokes the HDF5 wrapper compiler that should be installed
alongside HDF5.  Depending upon the HDF5 Configuration, the wrapper
compiler is called either h5cc or h5pcc.  If this succeeds, the module
will then call the compiler with the \-show argument to see what flags
are used when compiling an HDF5 client application.
.sp
The module will optionally accept the COMPONENTS argument.  If no
COMPONENTS are specified, then the find module will default to finding
only the HDF5 C library.  If one or more COMPONENTS are specified, the
module will attempt to find the language bindings for the specified
components.  The only valid components are C, CXX, Fortran, HL, and
Fortran_HL.  If the COMPONENTS argument is not given, the module will
attempt to find only the C bindings.
.sp
On UNIX systems, this module will read the variable
HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a
static link to a dynamic link for HDF5 and all of it\(aqs dependencies.
To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES
variable is set before the call to find_package.
.sp
To provide the module with a hint about where to find your HDF5
installation, you can set the environment variable HDF5_ROOT.  The
Find module will then look in this path when searching for HDF5
executables, paths, and libraries.
.sp
Both the serial and parallel HDF5 wrappers are considered and the first
directory to contain either one will be used.  In the event that both appear
in the same directory the serial version is preferentially selected. This
behavior can be reversed by setting the variable HDF5_PREFER_PARALLEL to
true.
.sp
In addition to finding the includes and libraries required to compile
an HDF5 client application, this module also makes an effort to find
tools that come with the HDF5 distribution that may be useful for
regression testing.
.sp
This module will define the following variables:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
HDF5_FOUND \- true if HDF5 was found on the system
HDF5_VERSION \- HDF5 version in format Major.Minor.Release

.sp
Available components are: C CXX Fortran and HL.  For each enabled language
binding, a corresponding HDF5_${LANG}_LIBRARIES variable will be defined.

also be defined.  With all components enabled, the following variables will be defined:

Windows registry
.IP \(bu 2
OS X: The installed versions of Matlab are given by the MATLAB
paths in \fB/Application\fP\&. If no such application is found, it falls back
to the one that might be accessible from the PATH.
.IP \(bu 2

Additional information is provided when \fBMATLAB_FIND_DEBUG\fP is set.
When a Matlab binary is found automatically and the \fBMATLAB_VERSION\fP

On Windows, it can make a window running Matlab appear.
.sp
The mapping of the release names and the version of Matlab is performed by
defining pairs (name, version).  The variable
\fBMATLAB_ADDITIONAL_VERSIONS\fP may be provided before the call to
the \fBfind_package()\fP in order to handle additional versions.
.sp
A Matlab scripts can be added to the set of tests using the
\fBmatlab_add_unit_test()\fP\&. By default, the Matlab unit test framework
will be used (>= 2013a) to run this script, but regular \fB\&.m\fP files
returning an exit code can be used as well (0 indicating a success).

.B \fBSymbol clash in a MEX target\fP
By default, every symbols inside a MEX
file defined with the command \fBmatlab_add_mex()\fP have hidden
visibility, except for the entry point. This is the default behaviour of
the MEX compiler, which lowers the risk of symbol collision between the
libraries shipped with Matlab, and the libraries to which the MEX file is
linking to. This is also the default on Windows platforms.
.sp
However, this is not sufficient in certain case, where for instance your
MEX file is linking against libraries that are already loaded by Matlab,
even if those libraries have different SONAMES.
A possible solution is to hide the symbols of the libraries to which the
MEX target is linking to. This can be achieved in GNU GCC compilers with
the linker option \fB\-Wl,\-\-exclude\-libs,ALL\fP\&.
.TP
.B \fBTests using GPU resources\fP
in case your MEX file is using the GPU and
in order to be able to run unit tests on this MEX file, the GPU resources
should be properly released by Matlab. A possible solution is to make
Matlab aware of the use of the GPU resources in the session, which can be
performed by a command such as \fBD = gpuDevice()\fP at the beginning of
the test script (or via a fixture).

.SS Usage
.sp
To use this module, simply call FindMPI from a CMakeLists.txt file, or
run \fBfind_package(MPI)\fP, then run CMake.  If you are happy with the
auto\-detected configuration for your language, then you\(aqre done.  If
not, you have two options:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
1. Set MPI_<lang>_COMPILER to the MPI wrapper (mpicc, etc.) of your
   choice and reconfigure.  FindMPI will attempt to determine all the
   necessary variables using THAT compiler\(aqs compile and link flags.
2. If this fails, or if your MPI implementation does not come with
   a compiler wrapper, then set both MPI_<lang>_LIBRARIES and
   MPI_<lang>_INCLUDE_PATH.  You may also set any other variables
   listed above, but these two are required.  This will circumvent
   autodetection entirely.
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
When configuration is successful, \fBMPI_<lang>_COMPILER\fP will be set to
the compiler wrapper for <lang>, if it was found.  \fBMPI_<lang>_FOUND\fP
and other variables above will be set if any MPI implementation was
found for <lang>, regardless of whether a compiler was found.
.sp
When using \fBMPIEXEC\fP to execute MPI applications, you should typically
use all of the \fBMPIEXEC\fP flags as follows:
.INDENT 0.0
.INDENT 3.5
.sp

${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS
  ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS

.SS FindosgAnimation
.sp
This is part of the Findosg* suite used to find OpenSceneGraph
components.  Each component is separate and you must opt in to each
module.  You must also opt into OpenGL and OpenThreads (and Producer
if needed) as these modules won\(aqt do it for you.  This is to allow you
control over your own system piece by piece in case you need to opt
out of certain components or change the Find behavior for a particular
module (perhaps because the default FindOpenGL.cmake module doesn\(aqt
work with your system as an example).  If you want to use a more
convenient module that includes everything, use the
FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

.SS FindPackageHandleStandardArgs
.sp
This module provides a function intended to be used in \fIFind Modules\fP
implementing \fBfind_package(<PackageName>)\fP calls.  It handles the
\fBREQUIRED\fP, \fBQUIET\fP and version\-related arguments of \fBfind_package\fP\&.
It also sets the \fB<PackageName>_FOUND\fP variable.  The package is
considered found if all variables listed contain valid results, e.g.
valid filepaths.
.INDENT 0.0
.TP
.B find_package_handle_standard_args
There are two signatures:
.INDENT 7.0
.INDENT 3.5
.sp
.nf
.ft C
find_package_handle_standard_args(<PackageName>
  (DEFAULT_MSG|<custom\-failure\-message>)
  <required\-var>...

  [FOUND_VAR <result\-var>]
  [REQUIRED_VARS <required\-var>...]

  [HANDLE_COMPONENTS]
  [CONFIG_MODE]
  [FAIL_MESSAGE <custom\-failure\-message>]
  )
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
The \fB<PackageName>_FOUND\fP variable will be set to \fBTRUE\fP if all
the variables \fB<required\-var>...\fP are valid and any optional
constraints are satisfied, and \fBFALSE\fP otherwise.  A success or
failure message may be displayed based on the results and on
whether the \fBREQUIRED\fP and/or \fBQUIET\fP option was given to
the \fBfind_package()\fP call.
.sp
The options are:
.INDENT 7.0
.TP
.B \fB(DEFAULT_MSG|<custom\-failure\-message>)\fP
In the simple signature this specifies the failure message.
Use \fBDEFAULT_MSG\fP to ask for a default message to be computed
(recommended).  Not valid in the full signature.
.TP
.B \fBFOUND_VAR <result\-var>\fP
Obsolete.  Specifies either \fB<PackageName>_FOUND\fP or
\fB<PACKAGENAME>_FOUND\fP as the result variable.  This exists only
for compatibility with older versions of CMake and is now ignored.
Result variables of both names are always set for compatibility.
.TP
.B \fBREQUIRED_VARS <required\-var>...\fP
Specify the variables which are required for this package.
These may be named in the generated failure message asking the
user to set the missing variable values.  Therefore these should
typically be cache entries such as \fBFOO_LIBRARY\fP and not output
variables like \fBFOO_LIBRARIES\fP\&.
.TP
.B \fBVERSION_VAR <version\-var>\fP
Specify the name of a variable that holds the version of the package
that has been found.  This version will be checked against the
(potentially) specified required version given to the
\fBfind_package()\fP call, including its \fBEXACT\fP option.
The default messages include information about the required
version and the version which has been actually found, both
if the version is ok or not.
.TP
.B \fBHANDLE_COMPONENTS\fP
Enable handling of package components.  In this case, the command
will report which components have been found and which are missing,
and the \fB<PackageName>_FOUND\fP variable will be set to \fBFALSE\fP
if any of the required components (i.e. not the ones listed after
the \fBOPTIONAL_COMPONENTS\fP option of \fBfind_package()\fP) are
missing.
.TP
.B \fBCONFIG_MODE\fP
Specify that the calling find module is a wrapper around a
call to \fBfind_package(<PackageName> NO_MODULE)\fP\&.  This implies
a \fBVERSION_VAR\fP value of \fB<PackageName>_VERSION\fP\&.  The command
will automatically check whether the package configuration file
was found.
.TP
.B \fBFAIL_MESSAGE <custom\-failure\-message>\fP
Specify a custom failure message instead of using the default
generated message.  Not recommended.

.UNINDENT
.UNINDENT
.sp
The \fBLibXml2\fP package is considered to be found if both
\fBLIBXML2_LIBRARY\fP and \fBLIBXML2_INCLUDE_DIR\fP are valid.
Then also \fBLibXml2_FOUND\fP is set to \fBTRUE\fP\&.  If it is not found
and \fBREQUIRED\fP was used, it fails with a
\fBmessage(FATAL_ERROR)\fP, independent whether \fBQUIET\fP was
used or not.  If it is found, success will be reported, including
the content of the first \fB<required\-var>\fP\&.  On repeated CMake runs,
the same message will not be printed again.
.sp
Example for the full signature:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
find_package_handle_standard_args(LibArchive
  REQUIRED_VARS LibArchive_LIBRARY LibArchive_INCLUDE_DIR
  VERSION_VAR LibArchive_VERSION)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
In this case, the \fBLibArchive\fP package is considered to be found if
both \fBLibArchive_LIBRARY\fP and \fBLibArchive_INCLUDE_DIR\fP are valid.
Also the version of \fBLibArchive\fP will be checked by using the version
contained in \fBLibArchive_VERSION\fP\&.  Since no \fBFAIL_MESSAGE\fP is given,
the default messages will be printed.

directory for \fBautomoc4\fP\&.  Then the call to
\fBfind_package_handle_standard_args\fP produces a proper success/failure
message.
.SS FindPackageMessage
.sp
FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")
.sp
This macro is intended to be used in FindXXX.cmake modules files.  It
will print a message once for each unique find result.  This is useful
for telling the user where a package was found.  The first argument
specifies the name (XXX) of the package.  The second argument
specifies the message to display.  The third argument lists details
about the find result so that if they change the message will be
displayed again.  The macro also obeys the QUIET argument to the
find_package command.

Each component is separate and you must opt in to each module.  You

the Find behavior for a particular module (perhaps because the default
FindOpenGL.cmake module doesn\(aqt work with your system as an example).
If you want to use a more convenient module that includes everything,

modules.

.SS Qt Build Tools
.sp
Qt relies on some bundled tools for code generation, such as \fBmoc\fP for
meta\-object code generation,\(ga\(gauic\(ga\(ga for widget layout and population,
and \fBrcc\fP for virtual filesystem content generation.  These tools may be
automatically invoked by \fBcmake(1)\fP if the appropriate conditions
are met.  See \fBcmake\-qt(7)\fP for more.
.SS Qt Macros
.sp
In some cases it can be necessary or useful to invoke the Qt build tools in a

macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... [TARGET tgt])
      The qt4_automoc macro is obsolete.  Use the CMAKE_AUTOMOC feature instead.
      This macro is still experimental.
      It can be used to have moc automatically handled.
      So if you have the files foo.h and foo.cpp, and in foo.h a
      a class uses the Q_OBJECT macro, moc has to run on it. If you don\(aqt
      want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
      #include "foo.moc"
      in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will
      scan all listed files at cmake\-time for such included moc files and if it
      finds them cause a rule to be generated to run moc at build time on the
      accompanying header file foo.h.
      If a source file has the SKIP_AUTOMOC property set it will be ignored by
      this macro.
      If the <tgt> is specified, the INTERFACE_INCLUDE_DIRECTORIES and
      INTERFACE_COMPILE_DEFINITIONS from the <tgt> are passed to moc.

       This function is obsolete. Use target_link_libraries with IMPORTED targets

       Make <target> use the <modules> from Qt. Using a Qt module means
       to link to the library, add the relevant include directories for the
       module, and add the relevant compiler defines for using the module.
       Modules are roughly equivalent to components of Qt4, so usage would be
       something like:
        qt4_use_modules(myexe Core Gui Declarative)
       to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument
       can be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the

guidelines.  Added a search for SDLmain which is needed by some
platforms.  Added a search for threads which is needed by some
platforms.  Added needed compile switches for MinGW.

Note that the header path has changed from SDL/SDL.h to just SDL.h
This needed to change because "proper" SDL convention is #include
"SDL.h", not <SDL/SDL.h>.  This is done for portability reasons
because not all systems place things in SDL/ (see FreeBSD).

Typically, you should not use these variables directly, and you should

audio libraries (if needed) to successfully compile on your system.
.sp
Created by Eric Wing.  This module is a bit more complicated than the
other FindSDL* family modules.  The reason is that SDL_sound can be
compiled in a large variety of different ways which are independent of
platform.  SDL_sound may dynamically link against other 3rd party
libraries to get additional codec support, such as Ogg Vorbis, SMPEG,
ModPlug, MikMod, FLAC, Speex, and potentially others.  Under some
circumstances which I don\(aqt fully understand, there seems to be a
requirement that dependent libraries of libraries you use must also be
explicitly linked against in order to successfully compile.  SDL_sound
does not currently have any system in place to know how it was
compiled.  So this CMake module does the hard work in trying to
discover which 3rd party libraries are required for building (if any).
This module uses a brute force approach to create a test program that
uses SDL_sound, and then tries to build it.  If the build fails, it
parses the error output for known symbol names to figure out which
libraries are needed.

   Let\(aqs leave that choice to the user by allowing him to assign

   confusion regarding the location of this file in an installed Tcl/Tk

.SS Module Functions
.INDENT 0.0
.TP
.B FortranCInterface_HEADER
The \fBFortranCInterface_HEADER\fP function is provided to generate a
C header file containing macros to mangle symbol names:
.INDENT 7.0
.INDENT 3.5
.sp
.nf
.ft C
FortranCInterface_HEADER(<file>
                         [MACRO_NAMESPACE <macro\-ns>]
                         [SYMBOL_NAMESPACE <ns>]
                         [SYMBOLS [<module>:]<function> ...])
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
It generates in \fB<file>\fP definitions of the following macros:
.INDENT 7.0
.INDENT 3.5
.sp
.nf
.ft C
#define FortranCInterface_GLOBAL (name,NAME) ...
#define FortranCInterface_GLOBAL_(name,NAME) ...
#define FortranCInterface_MODULE (mod,name, MOD,NAME) ...
#define FortranCInterface_MODULE_(mod,name, MOD,NAME) ...
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
These macros mangle four categories of Fortran symbols, respectively:
.INDENT 7.0
.IP \(bu 2
Global symbols without \(aq_\(aq: \fBcall mysub()\fP
.IP \(bu 2
Global symbols with \(aq_\(aq   : \fBcall my_sub()\fP
.IP \(bu 2
Module symbols without \(aq_\(aq: \fBuse mymod; call mysub()\fP
.IP \(bu 2
Module symbols with \(aq_\(aq   : \fBuse mymod; call my_sub()\fP
.UNINDENT
.sp
If mangling for a category is not known, its macro is left undefined.
All macros require raw names in both lower case and upper case.
.sp
The options are:
.INDENT 7.0
.TP
.B \fBMACRO_NAMESPACE\fP
Replace the default \fBFortranCInterface_\fP prefix with a given
namespace \fB<macro\-ns>\fP\&.
.TP
.B \fBSYMBOLS\fP
List symbols to mangle automatically with C preprocessor definitions:
.INDENT 7.0
.INDENT 3.5
.sp
.nf
.ft C
<function>          ==> #define <ns><function> ...
<module>:<function> ==> #define <ns><module>_<function> ...
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
If the mangling for some symbol is not known then no preprocessor
definition is created, and a warning is displayed.
.TP
.B \fBSYMBOL_NAMESPACE\fP
Prefix all preprocessor definitions generated by the \fBSYMBOLS\fP
option with a given namespace \fB<ns>\fP\&.
.UNINDENT
.UNINDENT
.INDENT 0.0
.TP
.B FortranCInterface_VERIFY
The \fBFortranCInterface_VERIFY\fP function is provided to verify
that the Fortran and C/C++ compilers work together:
.INDENT 7.0
.INDENT 3.5
.sp
.nf
.ft C
FortranCInterface_VERIFY([CXX] [QUIET])
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
It tests whether a simple test executable using Fortran and C (and C++
when the CXX option is given) compiles and links successfully.  The
result is stored in the cache entry \fBFortranCInterface_VERIFIED_C\fP
(or \fBFortranCInterface_VERIFIED_CXX\fP if \fBCXX\fP is given) as a boolean.
If the check fails and \fBQUIET\fP is not given the function terminates with a
fatal error message describing the problem.  The purpose of this check
is to stop a build early for incompatible compiler combinations.  The
test is built in the \fBRelease\fP configuration.
.UNINDENT
.SS Example Usage
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
include(FortranCInterface)
FortranCInterface_HEADER(FC.h MACRO_NAMESPACE "FC_")
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
This creates a "FC.h" header that defines mangling macros \fBFC_GLOBAL()\fP,
\fBFC_GLOBAL_()\fP, \fBFC_MODULE()\fP, and \fBFC_MODULE_()\fP\&.
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
include(FortranCInterface)
FortranCInterface_HEADER(FCMangle.h
                         MACRO_NAMESPACE "FC_"
                         SYMBOL_NAMESPACE "FC_"
                         SYMBOLS mysub mymod:my_sub)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
This creates a "FCMangle.h" header that defines the same \fBFC_*()\fP
mangling macros as the previous example plus preprocessor symbols
\fBFC_mysub\fP and \fBFC_mymod_my_sub\fP\&.
.SS Additional Manglings
.sp
FortranCInterface is aware of possible \fBGLOBAL\fP and \fBMODULE\fP manglings
for many Fortran compilers, but it also provides an interface to specify
new possible manglings.  Set the variables:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
FortranCInterface_GLOBAL_SYMBOLS
FortranCInterface_MODULE_SYMBOLS
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
before including FortranCInterface to specify manglings of the symbols
\fBMySub\fP, \fBMy_Sub\fP, \fBMyModule:MySub\fP, and \fBMy_Module:My_Sub\fP\&.
For example, the code:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
set(FortranCInterface_GLOBAL_SYMBOLS mysub_ my_sub__ MYSUB_)
  #                                  ^^^^^  ^^^^^^   ^^^^^
set(FortranCInterface_MODULE_SYMBOLS
    __mymodule_MOD_mysub __my_module_MOD_my_sub)
  #   ^^^^^^^^     ^^^^^   ^^^^^^^^^     ^^^^^^
include(FortranCInterface)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
tells FortranCInterface to try given \fBGLOBAL\fP and \fBMODULE\fP manglings.
(The carets point at raw symbol names for clarity in this example but
are not needed.)
.SS GenerateExportHeader
.sp
Function for generation of export macros for libraries
.sp
This module provides the function GENERATE_EXPORT_HEADER().
.sp
The \fBGENERATE_EXPORT_HEADER\fP function can be used to generate a file
suitable for preprocessor inclusion which contains EXPORT macros to be
used in library classes:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
GENERATE_EXPORT_HEADER( LIBRARY_TARGET
          [BASE_NAME <base_name>]
          [EXPORT_MACRO_NAME <export_macro_name>]
          [EXPORT_FILE_NAME <export_file_name>]
          [DEPRECATED_MACRO_NAME <deprecated_macro_name>]
          [NO_EXPORT_MACRO_NAME <no_export_macro_name>]
          [STATIC_DEFINE <static_define>]
          [NO_DEPRECATED_MACRO_NAME <no_deprecated_macro_name>]
          [DEFINE_NO_DEPRECATED]
          [PREFIX_NAME <prefix_name>]
)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
The target properties \fBCXX_VISIBILITY_PRESET\fP
and \fBVISIBILITY_INLINES_HIDDEN\fP can be used to add the appropriate
compile flags for targets.  See the documentation of those target properties,
and the convenience variables
\fBCMAKE_CXX_VISIBILITY_PRESET\fP and
\fBCMAKE_VISIBILITY_INLINES_HIDDEN\fP\&.
.sp
By default \fBGENERATE_EXPORT_HEADER()\fP generates macro names in a file
name determined by the name of the library.  This means that in the
simplest case, users of \fBGenerateExportHeader\fP will be equivalent to:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
set(CMAKE_CXX_VISIBILITY_PRESET hidden)
set(CMAKE_VISIBILITY_INLINES_HIDDEN 1)
add_library(somelib someclass.cpp)
generate_export_header(somelib)
install(TARGETS somelib DESTINATION ${LIBRARY_INSTALL_DIR})
install(FILES
 someclass.h
 ${PROJECT_BINARY_DIR}/somelib_export.h DESTINATION ${INCLUDE_INSTALL_DIR}
)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
And in the ABI header files:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
#include "somelib_export.h"
class SOMELIB_EXPORT SomeClass {
  ...
};
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
The CMake fragment will generate a file in the
\fB${CMAKE_CURRENT_BINARY_DIR}\fP called \fBsomelib_export.h\fP containing the
macros \fBSOMELIB_EXPORT\fP, \fBSOMELIB_NO_EXPORT\fP, \fBSOMELIB_DEPRECATED\fP,
\fBSOMELIB_DEPRECATED_EXPORT\fP and \fBSOMELIB_DEPRECATED_NO_EXPORT\fP\&.  The
resulting file should be installed with other headers in the library.
.sp
The \fBBASE_NAME\fP argument can be used to override the file name and the
names used for the macros:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
add_library(somelib someclass.cpp)
generate_export_header(somelib
  BASE_NAME other_name
)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
Generates a file called \fBother_name_export.h\fP containing the macros
\fBOTHER_NAME_EXPORT\fP, \fBOTHER_NAME_NO_EXPORT\fP and \fBOTHER_NAME_DEPRECATED\fP
etc.
.sp
The \fBBASE_NAME\fP may be overridden by specifiying other options in the
function.  For example:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
add_library(somelib someclass.cpp)
generate_export_header(somelib
  EXPORT_MACRO_NAME OTHER_NAME_EXPORT
)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
creates the macro \fBOTHER_NAME_EXPORT\fP instead of \fBSOMELIB_EXPORT\fP, but
other macros and the generated file name is as default:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
add_library(somelib someclass.cpp)
generate_export_header(somelib
  DEPRECATED_MACRO_NAME KDE_DEPRECATED
)
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
creates the macro \fBKDE_DEPRECATED\fP instead of \fBSOMELIB_DEPRECATED\fP\&.
.sp
If \fBLIBRARY_TARGET\fP is a static library, macros are defined without
values.

.SS Special Cases
.sp
The following values of \fBCMAKE_INSTALL_PREFIX\fP are special:
.sp
\fB/\fP
.INDENT 0.0
.INDENT 3.5
For \fB<dir>\fP other than the \fBSYSCONFDIR\fP and \fBLOCALSTATEDIR\fP,
the value of \fBCMAKE_INSTALL_<dir>\fP is prefixed with \fBusr/\fP if
it is not user\-specified as an absolute path.  For example, the
\fBINCLUDEDIR\fP value \fBinclude\fP becomes \fBusr/include\fP\&.
This is required by the \fI\%GNU Coding Standards\fP, which state:
.INDENT 0.0
.INDENT 3.5
When building the complete GNU system, the prefix will be empty
and \fB/usr\fP will be a symbolic link to \fB/\fP\&.

.INDENT 0.0
.INDENT 3.5
For \fB<dir>\fP equal to \fBSYSCONFDIR\fP or \fBLOCALSTATEDIR\fP, the
\fBCMAKE_INSTALL_FULL_<dir>\fP is computed by prepending just \fB/\fP
to the value of \fBCMAKE_INSTALL_<dir>\fP if it is not user\-specified
as an absolute path.  For example, the \fBSYSCONFDIR\fP value \fBetc\fP
becomes \fB/etc\fP\&.  This is required by the \fI\%GNU Coding Standards\fP\&.
.UNINDENT
.UNINDENT
.sp
\fB/opt/...\fP
.INDENT 0.0
.INDENT 3.5
For \fB<dir>\fP equal to \fBSYSCONFDIR\fP or \fBLOCALSTATEDIR\fP, the
\fBCMAKE_INSTALL_FULL_<dir>\fP is computed by \fIappending\fP the prefix
to the value of \fBCMAKE_INSTALL_<dir>\fP if it is not user\-specified
as an absolute path.  For example, the \fBSYSCONFDIR\fP value \fBetc\fP

.SS InstallRequiredSystemLibraries
.sp
Include this module to search for compiler\-provided system runtime
libraries and add install rules for them.  Some optional variables
may be set prior to including the module to adjust behavior:
.INDENT 0.0
.TP
.B \fBCMAKE_INSTALL_SYSTEM_RUNTIME_LIBS\fP
Specify additional runtime libraries that may not be detected.
After inclusion any detected libraries will be appended to this.
.TP
.B \fBCMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP\fP
Set to TRUE to skip calling the \fBinstall(PROGRAMS)\fP command to
allow the includer to specify its own install rule, using the value of
\fBCMAKE_INSTALL_SYSTEM_RUNTIME_LIBS\fP to get the list of libraries.
.TP
.B \fBCMAKE_INSTALL_DEBUG_LIBRARIES\fP
Set to TRUE to install the debug runtime libraries when available
with MSVC tools.
.TP
.B \fBCMAKE_INSTALL_DEBUG_LIBRARIES_ONLY\fP
Set to TRUE to install only the debug runtime libraries with MSVC
tools even if the release runtime libraries are also available.
.TP
.B \fBCMAKE_INSTALL_UCRT_LIBRARIES\fP
Set to TRUE to install the Windows Universal CRT libraries for
app\-local deployment (e.g. to Windows XP).  This is meaningful
only with MSVC from Visual Studio 2015 or higher.
.TP
.B \fBCMAKE_INSTALL_MFC_LIBRARIES\fP
Set to TRUE to install the MSVC MFC runtime libraries.
.TP
.B \fBCMAKE_INSTALL_OPENMP_LIBRARIES\fP
Set to TRUE to install the MSVC OpenMP runtime libraries
.TP
.B \fBCMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION\fP
Specify the \fBinstall(PROGRAMS)\fP command \fBDESTINATION\fP
option.  If not specified, the default is \fBbin\fP on Windows
and \fBlib\fP elsewhere.
.TP
.B \fBCMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS\fP
Set to TRUE to disable warnings about required library files that
do not exist.  (For example, Visual Studio Express editions may
not provide the redistributable files.)
.TP
.B \fBCMAKE_INSTALL_SYSTEM_RUNTIME_COMPONENT\fP
Specify the \fBinstall(PROGRAMS)\fP command \fBCOMPONENT\fP
option.  If not specified, no such option will be used.

.SS MacroAddFileDependencies
.sp
MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...)
.sp
Using the macro MACRO_ADD_FILE_DEPENDENCIES() is discouraged.  There
are usually better ways to specify the correct dependencies.
.sp
MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...) is just a
convenience wrapper around the OBJECT_DEPENDS source file property.
You can just use set_property(SOURCE <file> APPEND PROPERTY
OBJECT_DEPENDS depend_files) instead.
.SS ProcessorCount
.sp
ProcessorCount(var)
.sp
Determine the number of processors/cores and save value in ${var}
.sp
Sets the variable named ${var} to the number of physical cores
available on the machine if the information can be determined.
Otherwise it is set to 0.  Currently this functionality is implemented
for AIX, cygwin, FreeBSD, HPUX, IRIX, Linux, Mac OS X, QNX, Sun and
Windows.
.sp
This function is guaranteed to return a positive integer (>=1) if it
succeeds.  It returns 0 if there\(aqs a problem determining the processor
count.
.sp

This function is intended to offer an approximation of the value of
the number of compute cores available on the current machine, such
that you may use that value for parallel building and parallel
testing.  It is meant to help utilize as much of the machine as seems
reasonable.  Of course, knowledge of what else might be running on the
machine simultaneously should be used when deciding whether to request
a machine\(aqs full capacity all for yourself.
.SS SelectLibraryConfigurations
.sp
select_library_configurations( basename )
.sp
This macro takes a library base name as an argument, and will choose
good values for basename_LIBRARY, basename_LIBRARIES,
basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE depending on what
has been found and set.  If only basename_LIBRARY_RELEASE is defined,
basename_LIBRARY will be set to the release value, and
basename_LIBRARY_DEBUG will be set to basename_LIBRARY_DEBUG\-NOTFOUND.
If only basename_LIBRARY_DEBUG is defined, then basename_LIBRARY will
take the debug value, and basename_LIBRARY_RELEASE will be set to
basename_LIBRARY_RELEASE\-NOTFOUND.
.sp
If the generator supports configuration types, then basename_LIBRARY
and basename_LIBRARIES will be set with debug and optimized flags
specifying the library to be used for the given configuration.  If no
build type has been set or the generator in use does not support
configuration types, then basename_LIBRARY and basename_LIBRARIES will
take only the release value, or the debug value if the release one is
not set.
.SS SquishTestScript
.sp
This script launches a GUI test using Squish.  You should not call the
script directly; instead, you should access it via the SQUISH_ADD_TEST
macro that is defined in FindSquish.cmake.
.sp
This script starts the Squish server, launches the test on the client,
and finally stops the squish server.  If any of these steps fail
(including if the tests do not pass) then a fatal error is raised.

cleared.  If nothing is found, the result will be <VAR>\-NOTFOUND, and
the search will be attempted again next time find_jar is invoked with
the same variable.  The name of the full path to a file that is
searched for is specified by the names listed after NAMES argument.
Additional search locations can be specified after the PATHS argument.
If you require special a version of a jar file you can specify it with
the VERSIONS argument.  The argument after DOC will be used for the

available in the \fB<output_files_var>\fP and may be consumed by the caller
for installation for example.  The \fBOUTPUT_DIR\fP specifies a relative

At least one \fB<compiler>\fP and one \fB<feature>\fP must be listed.  Compilers

\fB<PREFIX>_COMPILER_IS_<compiler>\fP is generated for each compiler
known to CMake to contain the value \fB0\fP or \fB1\fP\&.
.sp
Possible compiler identifiers are documented with the
\fBCMAKE_<LANG>_COMPILER_ID\fP variable.
Available features in this version of CMake are listed in the
\fBCMAKE_C_KNOWN_FEATURES\fP and
\fBCMAKE_CXX_KNOWN_FEATURES\fP global properties.
.sp
See the \fBcmake\-compile\-features(7)\fP manual for information on
compile features.
.SS Feature Test Macros
.sp
For each compiler, a preprocessor macro is generated matching
\fB<PREFIX>_COMPILER_IS_<compiler>\fP which has the content either \fB0\fP

compiler version components are generated matching
\fB<PREFIX>_COMPILER_VERSION_MAJOR\fP \fB<PREFIX>_COMPILER_VERSION_MINOR\fP
and \fB<PREFIX>_COMPILER_VERSION_PATCH\fP containing decimal values
for the corresponding compiler version components, if defined.
.sp
A preprocessor test is generated based on the compiler version
denoting whether each feature is enabled.  A preprocessor macro
matching \fB<PREFIX>_COMPILER_<FEATURE>\fP, where \fB<FEATURE>\fP is the
upper\-case \fB<feature>\fP name, is generated to contain the value
\fB0\fP or \fB1\fP depending on whether the compiler in use supports the
feature:

.SS Compatibility Implementation Macros
.sp
Some features are suitable for wrapping in a macro with a backward
compatibility implementation if the compiler does not support the feature.
.sp
When the \fBcxx_static_assert\fP feature is not provided by the compiler,
a compatibility implementation is available via the
\fB<PREFIX>_STATIC_ASSERT(COND)\fP and
\fB<PREFIX>_STATIC_ASSERT_MSG(COND, MSG)\fP function\-like macros. The macros
expand to \fBstatic_assert\fP where that compiler feature is available, and
to a compatibility implementation otherwise. In the first form, the
condition is stringified in the message field of \fBstatic_assert\fP\&.  In
the second form, the message \fBMSG\fP is passed to the message field of
\fBstatic_assert\fP, or ignored if using the backward compatibility
implementation.
.sp
The \fBcxx_attribute_deprecated\fP feature provides a macro definition
\fB<PREFIX>_DEPRECATED\fP, which expands to either the standard
\fB[[deprecated]]\fP attribute or a compiler\-specific decorator such
as \fB__attribute__((__deprecated__))\fP used by GNU compilers.
.sp
The \fBcxx_alignas\fP feature provides a macro definition

A use\-case which arises with such deprecation macros is the deprecation
of an entire library.  In that case, all public API in the library may
be decorated with the \fB<PREFIX>_DEPRECATED\fP macro.  This results in
very noisy build output when building the library itself, so the macro
may be may be defined to empty in that case when building the deprecated
library:
