NAME

       cmake-variables - CMake Variables Reference

VARIABLES THAT PROVIDE INFORMATION

CMAKE_ARGC
Number of command line arguments passed to CMake in script mode.

When run in -P script mode, CMake sets this variable to the number of command line
arguments. See also CMAKE_ARGV0, 1, 2 ...

CMAKE_ARGV0
Command line argument passed to CMake in script mode.

When run in -P script mode, CMake sets this variable to the first command line argument.
It then also sets CMAKE_ARGV1, CMAKE_ARGV2, ... and so on, up to the number of command
line arguments given. See also CMAKE_ARGC.

CMAKE_AR
Name of archiving tool for static libraries.

This specifies the name of the program that creates archive or static libraries.

CMAKE_BINARY_DIR
The path to the top level of the build tree.

This is the full path to the top level of the current CMake build tree. For an in-source
build, this would be the same as CMAKE_SOURCE_DIR.

When run in -P script mode, CMake sets the variables CMAKE_BINARY_DIR, CMAKE_SOURCE_DIR,
CMAKE_CURRENT_BINARY_DIR and CMAKE_CURRENT_SOURCE_DIR to the current working directory.

CMAKE_BUILD_TOOL
This variable exists only for backwards compatibility. It contains the same value as
CMAKE_MAKE_PROGRAM. Use that variable instead.

CMAKE_CACHEFILE_DIR
The directory with the CMakeCache.txt file.

This is the full path to the directory that has the CMakeCache.txt file in it. This is
the same as CMAKE_BINARY_DIR.

CMAKE_CACHE_MAJOR_VERSION
Major version of CMake used to create the CMakeCache.txt file

This stores the major version of CMake used to write a CMake cache file. It is only
different when a different version of CMake is run on a previously created cache file.

CMAKE_CACHE_MINOR_VERSION
Minor version of CMake used to create the CMakeCache.txt file

This stores the minor version of CMake used to write a CMake cache file. It is only
different when a different version of CMake is run on a previously created cache file.

CMAKE_CACHE_PATCH_VERSION
Patch version of CMake used to create the CMakeCache.txt file

This stores the patch version of CMake used to write a CMake cache file. It is only
different when a different version of CMake is run on a previously created cache file.

CMAKE_CFG_INTDIR
Build-time reference to per-configuration output subdirectory.

For native build systems supporting multiple configurations in the build tree (such as
Visual Studio Generators and Xcode), the value is a reference to a build-time variable
specifying the name of the per-configuration output subdirectory. On Makefile Generators
this evaluates to . because there is only one configuration in a build tree. Example
values:

$(IntDir) = Visual Studio 6
$(ConfigurationName) = Visual Studio 7, 8, 9
$(Configuration) = Visual Studio 10
$(CONFIGURATION) = Xcode
. = Make-based tools

Since these values are evaluated by the native build system, this variable is suitable
only for use in command lines that will be evaluated at build time. Example of intended
usage:

add_executable(mytool mytool.c)
add_custom_command(
OUTPUT out.txt
COMMAND ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool
${CMAKE_CURRENT_SOURCE_DIR}/in.txt out.txt
DEPENDS mytool in.txt
)
add_custom_target(drive ALL DEPENDS out.txt)

Note that CMAKE_CFG_INTDIR is no longer necessary for this purpose but has been left for
compatibility with existing projects. Instead add_custom_command() recognizes executable
target names in its COMMAND option, so
${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool can be replaced by just mytool.

This variable is read-only. Setting it is undefined behavior. In multi-configuration
build systems the value of this variable is passed as the value of preprocessor symbol
CMAKE_INTDIR to the compilation of all source files.

CMAKE_COMMAND
The full path to the cmake(1) executable.

This is the full path to the CMake executable cmake(1) which is useful from custom
commands that want to use the cmake -E option for portable system commands. (e.g.
/usr/local/bin/cmake)

CMAKE_CROSSCOMPILING
Is CMake currently cross compiling.

This variable will be set to true by CMake if CMake is cross compiling. Specifically if
the build platform is different from the target platform.

CMAKE_CROSSCOMPILING_EMULATOR
This variable is only used when CMAKE_CROSSCOMPILING is on. It should point to a command
on the host system that can run executable built for the target system.

The command will be used to run try_run() generated executables, which avoids manual
population of the TryRunResults.cmake file.

It is also used as the default value for the CROSSCOMPILING_EMULATOR target property of
executables.

CMAKE_CTEST_COMMAND
Full path to ctest(1) command installed with CMake.

This is the full path to the CTest executable ctest(1) which is useful from custom
commands that want to use the cmake(1) -E option for portable system commands.

CMAKE_CURRENT_BINARY_DIR
The path to the binary directory currently being processed.

This the full path to the build directory that is currently being processed by cmake.
Each directory added by add_subdirectory() will create a binary directory in the build
tree, and as it is being processed this variable will be set. For in-source builds this
is the current source directory being processed.

When run in -P script mode, CMake sets the variables CMAKE_BINARY_DIR, CMAKE_SOURCE_DIR,
CMAKE_CURRENT_BINARY_DIR and CMAKE_CURRENT_SOURCE_DIR to the current working directory.

CMAKE_CURRENT_LIST_DIR
Full directory of the listfile currently being processed.

As CMake processes the listfiles in your project this variable will always be set to the
directory where the listfile which is currently being processed (CMAKE_CURRENT_LIST_FILE)
is located. The value has dynamic scope. When CMake starts processing commands in a
source file it sets this variable to the directory where this file is located. When CMake
finishes processing commands from the file it restores the previous value. Therefore the
value of the variable inside a macro or function is the directory of the file invoking the
bottom-most entry on the call stack, not the directory of the file containing the macro or
function definition.

VARIABLES THAT CHANGE BEHAVIOR

BUILD_SHARED_LIBS
Global flag to cause add_library() to create shared libraries if on.

If present and true, this will cause all libraries to be built shared unless the library
was explicitly added as a static library. This variable is often added to projects as an
option() so that each user of a project can decide if they want to build the project using
shared or static libraries.

CMAKE_ABSOLUTE_DESTINATION_FILES
List of files which have been installed using an ABSOLUTE DESTINATION path.

This variable is defined by CMake-generated cmake_install.cmake scripts. It can be used
(read-only) by programs or scripts that source those install scripts. This is used by
some CPack generators (e.g. RPM).

CMAKE_APPBUNDLE_PATH
;-list of directories specifying a search path for OS X application bundles used by the
find_program(), and find_package() commands.

CMAKE_AUTOMOC_RELAXED_MODE
Switch between strict and relaxed automoc mode.

By default, AUTOMOC behaves exactly as described in the documentation of the AUTOMOC
target property. When set to TRUE, it accepts more input and tries to find the correct
input file for moc even if it differs from the documented behaviour. In this mode it e.g.
also checks whether a header file is intended to be processed by moc when a "foo.moc" file
has been included.

Relaxed mode has to be enabled for KDE4 compatibility.

CMAKE_BACKWARDS_COMPATIBILITY
Deprecated. See CMake Policy CMP0001 documentation.

CMAKE_BUILD_TYPE
Specifies the build type on single-configuration generators.

This statically specifies what build type (configuration) will be built in this build
tree. Possible values are empty, Debug, Release, RelWithDebInfo and MinSizeRel. This
variable is only meaningful to single-configuration generators (such as Makefile
Generators and Ninja) i.e. those which choose a single configuration when CMake runs to
generate a build tree as opposed to multi-configuration generators which offer selection
of the build configuration within the generated build environment. There are many
per-config properties and variables (usually following clean SOME_VAR_<CONFIG> order
conventions), such as CMAKE_C_FLAGS_<CONFIG>, specified as uppercase:
CMAKE_C_FLAGS_[DEBUG|RELEASE|RELWITHDEBINFO|MINSIZEREL]. For example, in a build tree
configured to build type Debug, CMake will see to having CMAKE_C_FLAGS_DEBUG settings get
added to the CMAKE_C_FLAGS settings. See also CMAKE_CONFIGURATION_TYPES.

CMAKE_COLOR_MAKEFILE
Enables color output when using the Makefile Generators.

When enabled, the generated Makefiles will produce colored output. Default is ON.

CMAKE_CONFIGURATION_TYPES
Specifies the available build types on multi-config generators.

This specifies what build types (configurations) will be available such as Debug, Release,
RelWithDebInfo etc. This has reasonable defaults on most platforms, but can be extended
to provide other build types. See also CMAKE_BUILD_TYPE for details of managing
configuration data, and CMAKE_CFG_INTDIR.

CMAKE_DEBUG_TARGET_PROPERTIES
Enables tracing output for target properties.

This variable can be populated with a list of properties to generate debug output for when
evaluating target properties. Currently it can only be used when evaluating the
INCLUDE_DIRECTORIES, COMPILE_DEFINITIONS, COMPILE_OPTIONS, AUTOUIC_OPTIONS, SOURCES,
COMPILE_FEATURES, POSITION_INDEPENDENT_CODE target properties and any other property
listed in COMPATIBLE_INTERFACE_STRING and other COMPATIBLE_INTERFACE_ properties. It
outputs an origin for each entry in the target property. Default is unset.

CMAKE_DISABLE_FIND_PACKAGE_<PackageName>
Variable for disabling find_package() calls.

Every non-REQUIRED find_package() call in a project can be disabled by setting the
variable CMAKE_DISABLE_FIND_PACKAGE_<PackageName> to TRUE. This can be used to build a
project without an optional package, although that package is installed.

This switch should be used during the initial CMake run. Otherwise if the package has
already been found in a previous CMake run, the variables which have been stored in the
cache will still be there. In that case it is recommended to remove the cache variables
for this package from the cache using the cache editor or cmake(1) -U

CMAKE_ERROR_DEPRECATED
Whether to issue errors for deprecated functionality.

If TRUE, use of deprecated functionality will issue fatal errors. If this variable is not
set, CMake behaves as if it were set to FALSE.

CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
Ask cmake_install.cmake script to error out as soon as a file with absolute INSTALL
DESTINATION is encountered.

The fatal error is emitted before the installation of the offending file takes place.
This variable is used by CMake-generated cmake_install.cmake scripts. If one sets this
variable to ON while running the script, it may get fatal error messages from the script.

CMAKE_EXPORT_COMPILE_COMMANDS
Enable/Disable output of compile commands during generation.

If enabled, generates a compile_commands.json file containing the exact compiler calls for
all translation units of the project in machine-readable form. The format of the JSON
file looks like:

[
{
"directory": "/home/user/development/project",
"command": "/usr/bin/c++ ... -c ../foo/foo.cc",
"file": "../foo/foo.cc"
},

...

{
"directory": "/home/user/development/project",
"command": "/usr/bin/c++ ... -c ../foo/bar.cc",
"file": "../foo/bar.cc"
}
]

NOTE:
This option is implemented only by Makefile Generators and the Ninja. It is ignored on
other generators.

CMAKE_EXPORT_NO_PACKAGE_REGISTRY
Disable the export(PACKAGE) command.

In some cases, for example for packaging and for system wide installations, it is not
desirable to write the user package registry. If the CMAKE_EXPORT_NO_PACKAGE_REGISTRY
variable is enabled, the export(PACKAGE) command will do nothing.

See also Disabling the Package Registry.

CMAKE_SYSROOT
Path to pass to the compiler in the --sysroot flag.

The CMAKE_SYSROOT content is passed to the compiler in the --sysroot flag, if supported.
The path is also stripped from the RPATH/RUNPATH if necessary on installation. The
CMAKE_SYSROOT is also used to prefix paths searched by the find_* commands.

This variable may only be set in a toolchain file specified by the CMAKE_TOOLCHAIN_FILE
variable.

CMAKE_FIND_APPBUNDLE
This variable affects how find_* commands choose between OS X Application Bundles and
unix-style package components.

On Darwin or systems supporting OS X Application Bundles, the CMAKE_FIND_APPBUNDLE
variable can be set to empty or one of the following:

FIRST Try to find application bundles before standard programs. This is the default on
Darwin.

LAST Try to find application bundles after standard programs.

ONLY Only try to find application bundles.

NEVER Never try to find application bundles.

CMAKE_FIND_FRAMEWORK
This variable affects how find_* commands choose between OS X Frameworks and unix-style
package components.

On Darwin or systems supporting OS X Frameworks, the CMAKE_FIND_FRAMEWORK variable can be
set to empty or one of the following:

FIRST Try to find frameworks before standard libraries or headers. This is the default
on Darwin.

LAST Try to find frameworks after standard libraries or headers.

ONLY Only try to find frameworks.

NEVER Never try to find frameworks.

CMAKE_FIND_LIBRARY_PREFIXES
Prefixes to prepend when looking for libraries.

This specifies what prefixes to add to library names when the find_library() command looks
for libraries. On UNIX systems this is typically lib, meaning that when trying to find
the foo library it will look for libfoo.

CMAKE_FIND_LIBRARY_SUFFIXES
Suffixes to append when looking for libraries.

This specifies what suffixes to add to library names when the find_library() command looks
for libraries. On Windows systems this is typically .lib and .dll, meaning that when
trying to find the foo library it will look for foo.dll etc.

CMAKE_FIND_NO_INSTALL_PREFIX
Ignore the CMAKE_INSTALL_PREFIX when searching for assets.

CMake adds the CMAKE_INSTALL_PREFIX and the CMAKE_STAGING_PREFIX variable to the
CMAKE_SYSTEM_PREFIX_PATH by default. This variable may be set on the command line to
control that behavior.

Set CMAKE_FIND_NO_INSTALL_PREFIX to TRUE to tell find_package() not to search in the
CMAKE_INSTALL_PREFIX or CMAKE_STAGING_PREFIX by default. Note that the prefix may still
be searched for other reasons, such as being the same prefix as the CMake installation, or
for being a built-in system prefix.

CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY
Skip User Package Registry in find_package() calls.

In some cases, for example to locate only system wide installations, it is not desirable
to use the User Package Registry when searching for packages. If the
CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY variable is enabled, all the find_package()
commands will skip the User Package Registry as if they were called with the
NO_CMAKE_PACKAGE_REGISTRY argument.

See also Disabling the Package Registry.

CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY
Skip System Package Registry in find_package() calls.

In some cases, it is not desirable to use the System Package Registry when searching for
packages. If the CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY variable is enabled, all
the find_package() commands will skip the System Package Registry as if they were called
with the NO_CMAKE_SYSTEM_PACKAGE_REGISTRY argument.

See also Disabling the Package Registry.

CMAKE_FIND_PACKAGE_WARN_NO_MODULE
Tell find_package() to warn if called without an explicit mode.

If find_package() is called without an explicit mode option (MODULE, CONFIG, or NO_MODULE)
and no Find<pkg>.cmake module is in CMAKE_MODULE_PATH then CMake implicitly assumes that
the caller intends to search for a package configuration file. If no package
configuration file is found then the wording of the failure message must account for both
the case that the package is really missing and the case that the project has a bug and
failed to provide the intended Find module. If instead the caller specifies an explicit
mode option then the failure message can be more specific.

Set CMAKE_FIND_PACKAGE_WARN_NO_MODULE to TRUE to tell find_package() to warn when it
implicitly assumes Config mode. This helps developers enforce use of an explicit mode in
all calls to find_package() within a project.

CMAKE_FIND_ROOT_PATH
;-list of root paths to search on the filesystem.

This variable is most useful when cross-compiling. CMake uses the paths in this list as
alternative roots to find filesystem items with find_package(), find_library() etc.

CMAKE_FIND_ROOT_PATH_MODE_INCLUDE
This variable controls whether the CMAKE_FIND_ROOT_PATH and CMAKE_SYSROOT are used by
find_file() and find_path().

If set to ONLY, then only the roots in CMAKE_FIND_ROOT_PATH will be searched. If set to
NEVER, then the roots in CMAKE_FIND_ROOT_PATH will be ignored and only the host system
root will be used. If set to BOTH, then the host system paths and the paths in
CMAKE_FIND_ROOT_PATH will be searched.

CMAKE_FIND_ROOT_PATH_MODE_LIBRARY
This variable controls whether the CMAKE_FIND_ROOT_PATH and CMAKE_SYSROOT are used by
find_library().

CMAKE_FIND_ROOT_PATH_MODE_PACKAGE
This variable controls whether the CMAKE_FIND_ROOT_PATH and CMAKE_SYSROOT are used by
find_package().

CMAKE_FIND_ROOT_PATH_MODE_PROGRAM
This variable controls whether the CMAKE_FIND_ROOT_PATH and CMAKE_SYSROOT are used by
find_program().

CMAKE_FRAMEWORK_PATH
;-list of directories specifying a search path for OS X frameworks used by the
find_library(), find_package(), find_path(), and find_file() commands.

CMAKE_IGNORE_PATH
;-list of directories to be ignored by the find_program(), find_library(), find_file(),
and find_path() commands. This is useful in cross-compiling environments where some
system directories contain incompatible but possibly linkable libraries. For example, on
cross-compiled cluster environments, this allows a user to ignore directories containing
libraries meant for the front-end machine.

By default this is empty; it is intended to be set by the project. Note that
CMAKE_IGNORE_PATH takes a list of directory names, not a list of prefixes. To ignore
paths under prefixes (bin, include, lib, etc.), specify them explicitly.

See also the CMAKE_PREFIX_PATH, CMAKE_LIBRARY_PATH, CMAKE_INCLUDE_PATH, and
CMAKE_PROGRAM_PATH variables.

CMAKE_INCLUDE_PATH
;-list of directories specifying a search path for the find_file() and find_path()
commands. By default it is empty, it is intended to be set by the project. See also
CMAKE_SYSTEM_INCLUDE_PATH and CMAKE_PREFIX_PATH.

CMAKE_INCLUDE_DIRECTORIES_BEFORE
Whether to append or prepend directories by default in include_directories().

This variable affects the default behavior of the include_directories() command. Setting
this variable to ON is equivalent to using the BEFORE option in all uses of that command.

CMAKE_INCLUDE_DIRECTORIES_PROJECT_BEFORE
Whether to force prepending of project include directories.

This variable affects the order of include directories generated in compiler command
lines. If set to ON, it causes the CMAKE_SOURCE_DIR and the CMAKE_BINARY_DIR to appear
first.

CMAKE_INSTALL_DEFAULT_COMPONENT_NAME
Default component used in install() commands.

If an install() command is used without the COMPONENT argument, these files will be
grouped into a default component. The name of this default install component will be
taken from this variable. It defaults to Unspecified.

CMAKE_INSTALL_MESSAGE
Specify verbosity of installation script code generated by the install() command (using
the file(INSTALL) command). For paths that are newly installed or updated, installation
may print lines like:

-- Installing: /some/destination/path

For paths that are already up to date, installation may print lines like:

-- Up-to-date: /some/destination/path

The CMAKE_INSTALL_MESSAGE variable may be set to control which messages are printed:

ALWAYS Print both Installing and Up-to-date messages.

LAZY Print Installing but not Up-to-date messages.

NEVER Print neither Installing nor Up-to-date messages.

Other values have undefined behavior and may not be diagnosed.

If this variable is not set, the default behavior is ALWAYS.

CMAKE_INSTALL_PREFIX
Install directory used by install().

If make install is invoked or INSTALL is built, this directory is prepended onto all
install directories. This variable defaults to /usr/local on UNIX and c:/Program Files on
Windows.

On UNIX one can use the DESTDIR mechanism in order to relocate the whole installation.
DESTDIR means DESTination DIRectory. It is commonly used by makefile users in order to
install software at non-default location. It is usually invoked like this:

make DESTDIR=/home/john install

which will install the concerned software using the installation prefix, e.g. /usr/local
prepended with the DESTDIR value which finally gives /home/john/usr/local.

WARNING: DESTDIR may not be used on Windows because installation prefix usually contains a
drive letter like in C:/Program Files which cannot be prepended with some other prefix.

The installation prefix is also added to CMAKE_SYSTEM_PREFIX_PATH so that find_package(),
find_program(), find_library(), find_path(), and find_file() will search the prefix for
other software.

NOTE:
Use the GNUInstallDirs module to provide GNU-style options for the layout of
directories within the installation.

CMAKE_LIBRARY_PATH
;-list of directories specifying a search path for the find_library() command. By default
it is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_LIBRARY_PATH
and CMAKE_PREFIX_PATH.

CMAKE_MFC_FLAG
Tell cmake to use MFC for an executable or dll.

This can be set in a CMakeLists.txt file and will enable MFC in the application. It
should be set to 1 for the static MFC library, and 2 for the shared MFC library. This is
used in Visual Studio 6 and 7 project files. The CMakeSetup dialog used MFC and the
CMakeLists.txt looks like this:

add_definitions(-D_AFXDLL)
set(CMAKE_MFC_FLAG 2)
add_executable(CMakeSetup WIN32 ${SRCS})

CMAKE_MODULE_PATH
;-list of directories specifying a search path for CMake modules to be loaded by the the
include() or find_package() commands before checking the default modules that come with
CMake. By default it is empty, it is intended to be set by the project.

CMAKE_NOT_USING_CONFIG_FLAGS
Skip _BUILD_TYPE flags if true.

This is an internal flag used by the generators in CMake to tell CMake to skip the
_BUILD_TYPE flags.

CMAKE_POLICY_DEFAULT_CMP<NNNN>
Default for CMake Policy CMP<NNNN> when it is otherwise left unset.

Commands cmake_minimum_required(VERSION) and cmake_policy(VERSION) by default leave
policies introduced after the given version unset. Set CMAKE_POLICY_DEFAULT_CMP<NNNN> to
OLD or NEW to specify the default for policy CMP<NNNN>, where <NNNN> is the policy number.

This variable should not be set by a project in CMake code; use cmake_policy(SET) instead.
Users running CMake may set this variable in the cache (e.g.
-DCMAKE_POLICY_DEFAULT_CMP<NNNN>=<OLD|NEW>) to set a policy not otherwise set by the
project. Set to OLD to quiet a policy warning while using old behavior or to NEW to try
building the project with new behavior.

CMAKE_POLICY_WARNING_CMP<NNNN>
Explicitly enable or disable the warning when CMake Policy CMP<NNNN> is not set. This is
meaningful only for the few policies that do not warn by default:

• CMAKE_POLICY_WARNING_CMP0025 controls the warning for policy CMP0025.

• CMAKE_POLICY_WARNING_CMP0047 controls the warning for policy CMP0047.

• CMAKE_POLICY_WARNING_CMP0056 controls the warning for policy CMP0056.

• CMAKE_POLICY_WARNING_CMP0060 controls the warning for policy CMP0060.

• CMAKE_POLICY_WARNING_CMP0065 controls the warning for policy CMP0065.

This variable should not be set by a project in CMake code. Project developers running
CMake may set this variable in their cache to enable the warning (e.g.
-DCMAKE_POLICY_WARNING_CMP<NNNN>=ON). Alternatively, running cmake(1) with the
--debug-output, --trace, or --trace-expand option will also enable the warning.

CMAKE_PREFIX_PATH
;-list of directories specifying installation prefixes to be searched by the
find_package(), find_program(), find_library(), find_file(), and find_path() commands.
Each command will add appropriate subdirectories (like bin, lib, or include) as specified
in its own documentation.

By default this is empty. It is intended to be set by the project.

See also CMAKE_SYSTEM_PREFIX_PATH, CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH,
CMAKE_PROGRAM_PATH, and CMAKE_IGNORE_PATH.

CMAKE_PROGRAM_PATH
;-list of directories specifying a search path for the find_program() command. By default
it is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_PROGRAM_PATH
and CMAKE_PREFIX_PATH.

CMAKE_PROJECT_<PROJECT-NAME>_INCLUDE
A CMake language file or module to be included by the project() command. This is is
intended for injecting custom code into project builds without modifying their source.

CMAKE_SKIP_INSTALL_ALL_DEPENDENCY
Don't make the install target depend on the all target.

By default, the install target depends on the all target. This has the effect, that when
make install is invoked or INSTALL is built, first the all target is built, then the
installation starts. If CMAKE_SKIP_INSTALL_ALL_DEPENDENCY is set to TRUE, this dependency
is not created, so the installation process will start immediately, independent from
whether the project has been completely built or not.

CMAKE_STAGING_PREFIX
This variable may be set to a path to install to when cross-compiling. This can be useful
if the path in CMAKE_SYSROOT is read-only, or otherwise should remain pristine.

The CMAKE_STAGING_PREFIX location is also used as a search prefix by the find_* commands.
This can be controlled by setting the CMAKE_FIND_NO_INSTALL_PREFIX variable.

If any RPATH/RUNPATH entries passed to the linker contain the CMAKE_STAGING_PREFIX, the
matching path fragments are replaced with the CMAKE_INSTALL_PREFIX.

CMAKE_SYSTEM_APPBUNDLE_PATH
Search path for OS X application bundles used by the find_program(), and find_package()
commands. By default it contains the standard directories for the current system. It is
not intended to be modified by the project, use CMAKE_APPBUNDLE_PATH for this.

CMAKE_SYSTEM_FRAMEWORK_PATH
Search path for OS X frameworks used by the find_library(), find_package(), find_path(),
and find_file() commands. By default it contains the standard directories for the current
system. It is not intended to be modified by the project, use CMAKE_FRAMEWORK_PATH for
this.

CMAKE_SYSTEM_IGNORE_PATH
;-list of directories to be ignored by the find_program(), find_library(), find_file(),
and find_path() commands. This is useful in cross-compiling environments where some
system directories contain incompatible but possibly linkable libraries. For example, on
cross-compiled cluster environments, this allows a user to ignore directories containing
libraries meant for the front-end machine.

By default this contains a list of directories containing incompatible binaries for the
host system. See the CMAKE_IGNORE_PATH variable that is intended to be set by the
project.

See also the CMAKE_SYSTEM_PREFIX_PATH, CMAKE_SYSTEM_LIBRARY_PATH,
CMAKE_SYSTEM_INCLUDE_PATH, and CMAKE_SYSTEM_PROGRAM_PATH variables.

CMAKE_SYSTEM_INCLUDE_PATH
;-list of directories specifying a search path for the find_file() and find_path()
commands. By default this contains the standard directories for the current system. It
is not intended to be modified by the project; use CMAKE_INCLUDE_PATH for this. See also
CMAKE_SYSTEM_PREFIX_PATH.

CMAKE_SYSTEM_LIBRARY_PATH
;-list of directories specifying a search path for the find_library() command. By default
this contains the standard directories for the current system. It is not intended to be
modified by the project; use CMAKE_LIBRARY_PATH for this. See also
CMAKE_SYSTEM_PREFIX_PATH.

CMAKE_SYSTEM_PREFIX_PATH
;-list of directories specifying installation prefixes to be searched by the
find_package(), find_program(), find_library(), find_file(), and find_path() commands.
Each command will add appropriate subdirectories (like bin, lib, or include) as specified
in its own documentation.

By default this contains the standard directories for the current system, the
CMAKE_INSTALL_PREFIX, and the CMAKE_STAGING_PREFIX. It is not intended to be modified by
the project; use CMAKE_PREFIX_PATH for this.

See also CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_SYSTEM_PROGRAM_PATH,
and CMAKE_SYSTEM_IGNORE_PATH.

CMAKE_SYSTEM_PROGRAM_PATH
;-list of directories specifying a search path for the find_program() command. By default
this contains the standard directories for the current system. It is not intended to be
modified by the project; use CMAKE_PROGRAM_PATH for this. See also
CMAKE_SYSTEM_PREFIX_PATH.

CMAKE_USER_MAKE_RULES_OVERRIDE
Specify a CMake file that overrides platform information.

CMake loads the specified file while enabling support for each language from either the
project() or enable_language() commands. It is loaded after CMake's builtin compiler and
platform information modules have been loaded but before the information is used. The
file may set platform information variables to override CMake's defaults.

This feature is intended for use only in overriding information variables that must be set
before CMake builds its first test project to check that the compiler for a language
works. It should not be used to load a file in cases that a normal include() will work.
Use it only as a last resort for behavior that cannot be achieved any other way. For
example, one may set CMAKE_C_FLAGS_INIT to change the default value used to initialize
CMAKE_C_FLAGS before it is cached. The override file should NOT be used to set anything
that could be set after languages are enabled, such as variables like
CMAKE_RUNTIME_OUTPUT_DIRECTORY that affect the placement of binaries. Information set in
the file will be used for try_compile() and try_run() builds too.

CMAKE_WARN_DEPRECATED
Whether to issue warnings for deprecated functionality.

If not FALSE, use of deprecated functionality will issue warnings. If this variable is
not set, CMake behaves as if it were set to TRUE.

When running cmake(1), this option can be enabled with the -Wdeprecated option, or
disabled with the -Wno-deprecated option.

CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
Ask cmake_install.cmake script to warn each time a file with absolute INSTALL DESTINATION
is encountered.

This variable is used by CMake-generated cmake_install.cmake scripts. If one sets this
variable to ON while running the script, it may get warning messages from the script.

VARIABLES THAT DESCRIBE THE SYSTEM

APPLE
True if running on OS X.

Set to true on OS X.

BORLAND
True if the Borland compiler is being used.

This is set to true if the Borland compiler is being used.

CMAKE_CL_64
Using the 64-bit compiler from Microsoft

Set to true when using the 64-bit cl compiler from Microsoft.

CMAKE_COMPILER_2005
Using the Visual Studio 2005 compiler from Microsoft

Set to true when using the Visual Studio 2005 compiler from Microsoft.

CMAKE_HOST_APPLE
True for Apple OS X operating systems.

Set to true when the host system is Apple OS X.

CMAKE_HOST_SYSTEM_NAME
Name of the OS CMake is running on.

On systems that have the uname command, this variable is set to the output of uname -s.
Linux, Windows, and Darwin for OS X are the values found on the big three operating
systems.

CMAKE_HOST_SYSTEM_PROCESSOR
The name of the CPU CMake is running on.

On systems that support uname, this variable is set to the output of uname -p. On Windows
it is set to the value of the environment variable PROCESSOR_ARCHITECTURE.

CMAKE_HOST_SYSTEM
Composit Name of OS CMake is being run on.

This variable is the composite of CMAKE_HOST_SYSTEM_NAME and CMAKE_HOST_SYSTEM_VERSION,
e.g. ${CMAKE_HOST_SYSTEM_NAME}-${CMAKE_HOST_SYSTEM_VERSION}. If
CMAKE_HOST_SYSTEM_VERSION is not set, then this variable is the same as
CMAKE_HOST_SYSTEM_NAME.

CMAKE_HOST_SYSTEM_VERSION
The OS version CMake is running on.

A numeric version string for the system. On systems that support uname, this variable is
set to the output of uname -r. On other systems this is set to major-minor version
numbers.

CMAKE_HOST_UNIX
True for UNIX and UNIX like operating systems.

Set to true when the host system is UNIX or UNIX like (i.e. APPLE and CYGWIN).

CMAKE_HOST_WIN32
True on Windows systems, including Win64.

Set to true when the host system is Windows and on Cygwin.

CMAKE_LIBRARY_ARCHITECTURE_REGEX
Regex matching possible target architecture library directory names.

This is used to detect CMAKE_<LANG>_LIBRARY_ARCHITECTURE from the implicit linker search
path by matching the <arch> name.

CMAKE_LIBRARY_ARCHITECTURE
Target architecture library directory name, if detected.

This is the value of CMAKE_<LANG>_LIBRARY_ARCHITECTURE as detected for one of the enabled
languages.

CMAKE_OBJECT_PATH_MAX
Maximum object file full-path length allowed by native build tools.

CMake computes for every source file an object file name that is unique to the source file
and deterministic with respect to the full path to the source file. This allows multiple
source files in a target to share the same name if they lie in different directories
without rebuilding when one is added or removed. However, it can produce long full paths
in a few cases, so CMake shortens the path using a hashing scheme when the full path to an
object file exceeds a limit. CMake has a built-in limit for each platform that is
sufficient for common tools, but some native tools may have a lower limit. This variable
may be set to specify the limit explicitly. The value must be an integer no less than
128.

CMAKE_SYSTEM_NAME
The name of the operating system for which CMake is to build. See the
CMAKE_SYSTEM_VERSION variable for the OS version.

System Name for Host Builds
CMAKE_SYSTEM_NAME is by default set to the same value as the CMAKE_HOST_SYSTEM_NAME
variable so that the build targets the host system.

System Name for Cross Compiling
CMAKE_SYSTEM_NAME may be set explicitly when first configuring a new build tree in order
to enable cross compiling. In this case the CMAKE_SYSTEM_VERSION variable must also be
set explicitly.

CMAKE_SYSTEM_PROCESSOR
The name of the CPU CMake is building for.

This variable is the same as CMAKE_HOST_SYSTEM_PROCESSOR if you build for the host system
instead of the target system when cross compiling.

• The Green Hills MULTI generator sets this to ARM by default.

CMAKE_SYSTEM
Composite name of operating system CMake is compiling for.

This variable is the composite of CMAKE_SYSTEM_NAME and CMAKE_SYSTEM_VERSION, e.g.
${CMAKE_SYSTEM_NAME}-${CMAKE_SYSTEM_VERSION}. If CMAKE_SYSTEM_VERSION is not set, then
this variable is the same as CMAKE_SYSTEM_NAME.

CMAKE_SYSTEM_VERSION
The version of the operating system for which CMake is to build. See the
CMAKE_SYSTEM_NAME variable for the OS name.

System Version for Host Builds
When the CMAKE_SYSTEM_NAME variable takes its default value then CMAKE_SYSTEM_VERSION is
by default set to the same value as the CMAKE_HOST_SYSTEM_VERSION variable so that the
build targets the host system version.

In the case of a host build then CMAKE_SYSTEM_VERSION may be set explicitly when first
configuring a new build tree in order to enable targeting the build for a different
version of the host operating system than is actually running on the host. This is
allowed and not considered cross compiling so long as the binaries built for the specified
OS version can still run on the host.

System Version for Cross Compiling
When the CMAKE_SYSTEM_NAME variable is set explicitly to enable cross compiling then the
value of CMAKE_SYSTEM_VERSION must also be set explicitly to specify the target system
version.

CYGWIN
True for Cygwin.

Set to true when using Cygwin.

CMAKE_COMPILE_PDB_OUTPUT_DIRECTORY
Output directory for MS debug symbol .pdb files generated by the compiler while building
source files.

This variable is used to initialize the COMPILE_PDB_OUTPUT_DIRECTORY property on all the
targets.

CMAKE_COMPILE_PDB_OUTPUT_DIRECTORY_<CONFIG>
Per-configuration output directory for MS debug symbol .pdb files generated by the
compiler while building source files.

This is a per-configuration version of CMAKE_COMPILE_PDB_OUTPUT_DIRECTORY. This variable
is used to initialize the COMPILE_PDB_OUTPUT_DIRECTORY_<CONFIG> property on all the
targets.

CMAKE_<CONFIG>_POSTFIX

When a non-executable target is created its <CONFIG>_POSTFIX target property is
initialized with the value of this variable if it is set.

CMAKE_DEBUG_POSTFIX
See variable CMAKE_<CONFIG>_POSTFIX.

This variable is a special case of the more-general CMAKE_<CONFIG>_POSTFIX variable for
the DEBUG configuration.

CMAKE_ENABLE_EXPORTS
Specify whether an executable exports symbols for loadable modules.

Normally an executable does not export any symbols because it is the final program. It is
possible for an executable to export symbols to be used by loadable modules. When this
property is set to true CMake will allow other targets to link to the executable with the
TARGET_LINK_LIBRARIES() command. On all platforms a target-level dependency on the
executable is created for targets that link to it. For DLL platforms an import library
will be created for the exported symbols and then used for linking. All Windows-based
systems including Cygwin are DLL platforms. For non-DLL platforms that require all
symbols to be resolved at link time, such as OS X, the module will link to the executable
using a flag like -bundle_loader. For other non-DLL platforms the link rule is simply
ignored since the dynamic loader will automatically bind symbols when the module is
loaded.

This variable is used to initialize the target property ENABLE_EXPORTS for executable
targets.

This variable is used to initialize the GNUtoMS property on targets when they are created.
See that target property for additional information.

CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE
Automatically add the current source- and build directories to the
INTERFACE_INCLUDE_DIRECTORIES target property.

If this variable is enabled, CMake automatically adds for each shared library target,
static library target, module target and executable target, CMAKE_CURRENT_SOURCE_DIR and
CMAKE_CURRENT_BINARY_DIR to the INTERFACE_INCLUDE_DIRECTORIES target property. By default
CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE is OFF.

CMAKE_INCLUDE_CURRENT_DIR
Automatically add the current source- and build directories to the include path.

If this variable is enabled, CMake automatically adds CMAKE_CURRENT_SOURCE_DIR and
CMAKE_CURRENT_BINARY_DIR to the include path for each directory. These additional include
directories do not propagate down to subdirectories. This is useful mainly for
out-of-source builds, where files generated into the build tree are included by files
located in the source tree.

By default CMAKE_INCLUDE_CURRENT_DIR is OFF.

CMAKE_INSTALL_NAME_DIR
OS X directory name for installed targets.

CMAKE_INSTALL_NAME_DIR is used to initialize the INSTALL_NAME_DIR property on all targets.
See that target property for more information.

A semicolon-separated list specifying the rpath to use in installed targets (for platforms
that support it). This is used to initialize the target property INSTALL_RPATH for all
targets.

CMAKE_INSTALL_RPATH_USE_LINK_PATH
Add paths to linker search and installed rpath.

CMAKE_INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will append directories
in the linker search path and outside the project to the INSTALL_RPATH. This is used to
initialize the target property INSTALL_RPATH_USE_LINK_PATH for all targets.

CMAKE_IOS_INSTALL_COMBINED
Default value for IOS_INSTALL_COMBINED of targets.

This variable is used to initialize the IOS_INSTALL_COMBINED property on all the targets.
See that target property for additional information.

CMAKE_<LANG>_COMPILER_LAUNCHER
Default value for <LANG>_COMPILER_LAUNCHER target property. This variable is used to
initialize the property on each target as it is created. This is done only when <LANG> is
C or CXX.

CMAKE_<LANG>_INCLUDE_WHAT_YOU_USE
Default value for <LANG>_INCLUDE_WHAT_YOU_USE target property. This variable is used to
initialize the property on each target as it is created. This is done only when <LANG> is
C or CXX.

The flag will be used to add a .def file when creating a dll on Windows; this is only
defined on Windows.

CMAKE_LINK_DEPENDS_NO_SHARED
Whether to skip link dependencies on shared library files.

This variable initializes the LINK_DEPENDS_NO_SHARED property on targets when they are
created. See that target property for additional information.

CMAKE_LINK_INTERFACE_LIBRARIES
Default value for LINK_INTERFACE_LIBRARIES of targets.

This variable is used to initialize the LINK_INTERFACE_LIBRARIES property on all the
targets. See that target property for additional information.

CMAKE_LINK_LIBRARY_FILE_FLAG
Flag to be used to link a library specified by a path to its file.

The flag will be used before a library file path is given to the linker. This is needed
only on very few platforms.

CMAKE_LINK_LIBRARY_FLAG
Flag to be used to link a library into an executable.

The flag will be used to specify a library to link to an executable. On most compilers
this is -l.

CMAKE_MACOSX_BUNDLE

Linker flags to be used to create modules.

These flags will be used by the linker when creating a module.

CMAKE_NO_BUILTIN_CHRPATH
Do not use the builtin ELF editor to fix RPATHs on installation.

When an ELF binary needs to have a different RPATH after installation than it does in the
build tree, CMake uses a builtin editor to change the RPATH in the installed copy. If
this variable is set to true then CMake will relink the binary before installation instead
of using its builtin editor.

CMAKE_NO_SYSTEM_FROM_IMPORTED
Default value for NO_SYSTEM_FROM_IMPORTED of targets.

This variable is used to initialize the NO_SYSTEM_FROM_IMPORTED property on all the
targets. See that target property for additional information.

CMAKE_OSX_ARCHITECTURES
Target specific architectures for OS X and iOS.

This variable is used to initialize the OSX_ARCHITECTURES property on each target as it is
creaed. See that target property for additional information.

The value of this variable should be set prior to the first project() or enable_language()
command invocation because it may influence configuration of the toolchain and flags. It
is intended to be set locally by the user creating a build tree.

This variable is ignored on platforms other than OS X.

CMAKE_OSX_DEPLOYMENT_TARGET
Specify the minimum version of OS X on which the target binaries are to be deployed.
CMake uses this value for the -mmacosx-version-min flag and to help choose the default SDK
(see CMAKE_OSX_SYSROOT).

If not set explicitly the value is initialized by the MACOSX_DEPLOYMENT_TARGET environment
variable, if set, and otherwise computed based on the host platform.

This variable is ignored on platforms other than OS X.

CMAKE_OSX_SYSROOT
Specify the location or name of the OS X platform SDK to be used. CMake uses this value
to compute the value of the -isysroot flag or equivalent and to help the find_* commands
locate files in the SDK.

If not set explicitly the value is initialized by the SDKROOT environment variable, if
set, and otherwise computed based on the CMAKE_OSX_DEPLOYMENT_TARGET or the host platform.

This variable is ignored on platforms other than OS X.

CMAKE_PDB_OUTPUT_DIRECTORY
Output directory for MS debug symbol .pdb files generated by the linker for executable and

These flags will be used by the linker when creating a shared library.

CMAKE_SKIP_BUILD_RPATH
Do not include RPATHs in the build tree.

CMAKE_SKIP_INSTALL_RPATH
Do not include RPATHs in the install tree.

Normally CMake uses the build tree for the RPATH when building executables etc on systems
that use RPATH. When the software is installed the executables etc are relinked by CMake
to have the install RPATH. If this variable is set to true then the software is always
installed without RPATH, even if RPATH is enabled when building. This can be useful for
example to allow running tests from the build directory with RPATH enabled before the
installation step. To omit RPATH in both the build and install steps, use
CMAKE_SKIP_RPATH instead.

CMAKE_STATIC_LINKER_FLAGS_<CONFIG>
Flags to be used when linking a static library.

Same as CMAKE_C_FLAGS_* but used by the linker when creating static libraries.

CMAKE_STATIC_LINKER_FLAGS
Linker flags to be used to create static libraries.

These flags will be used by the linker when creating a static library.

CMAKE_TRY_COMPILE_CONFIGURATION
Build configuration used for try_compile() and try_run() projects.

Projects built by try_compile() and try_run() are built synchronously during the CMake
configuration step. Therefore a specific build configuration must be chosen even if the
generated build system supports multiple configurations.

CMAKE_USE_RELATIVE_PATHS
This variable has no effect. The partially implemented effect it had in previous releases
was removed in CMake 3.4.

CMAKE_VISIBILITY_INLINES_HIDDEN
Default value for the VISIBILITY_INLINES_HIDDEN target property when a target is created.

CMAKE_VS_INCLUDE_INSTALL_TO_DEFAULT_BUILD
Include INSTALL target to default build.

In Visual Studio solution, by default the INSTALL target will not be part of the default
build. Setting this variable will enable the INSTALL target to be part of the default
build.

Tell the Xcode generator to set '<an-attribute>' to a given value in the generated Xcode
project. Ignored on other generators.

See the XCODE_ATTRIBUTE_<an-attribute> target property to set attributes on a specific
target.

Contents of CMAKE_XCODE_ATTRIBUTE_<an-attribute> may use "generator expressions" with the
syntax $<...>. See the cmake-generator-expressions(7) manual for available expressions.
See the cmake-buildsystem(7) manual for more on defining buildsystem properties.

EXECUTABLE_OUTPUT_PATH
Old executable location variable.

The target property RUNTIME_OUTPUT_DIRECTORY supercedes this variable for a target if it
is set. Executable targets are otherwise placed in this directory.

LIBRARY_OUTPUT_PATH
Old library location variable.

The target properties ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and
RUNTIME_OUTPUT_DIRECTORY supercede this variable for a target if they are set. Library
targets are otherwise placed in this directory.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

   CMAKE_Fortran_MODDIR_DEFAULT
       Fortran default module output directory.

       Most  Fortran compilers write .mod files to the current working directory.  For those that
       do not, this is set to . and used when the Fortran_MODULE_DIRECTORY target property is not
       set.

   CMAKE_Fortran_MODDIR_FLAG

       This  stores  the  flag  needed  to  pass the value of the Fortran_MODULE_DIRECTORY target
       property to the compiler.

   CMAKE_Fortran_MODOUT_FLAG
       Fortran flag to enable module output.

       Most Fortran compilers write .mod files out by default.  For others, this stores the  flag
       needed to enable module output.

       This variable is not guaranteed to be defined for all compilers or languages.

   CMAKE_<LANG>_COMPILER_LOADED
       Defined to true if the language is enabled.

       When language <LANG> is enabled by project() or enable_language() this variable is defined
       to 1.

   CMAKE_<LANG>_COMPILER
       The full path to the compiler for LANG.

       This  is  the  command  that  will  be used as the <LANG> compiler.  Once set, you can not
       change this variable.

   CMAKE_<LANG>_COMPILER_EXTERNAL_TOOLCHAIN
       The external toolchain for cross-compiling, if supported.

       Some compiler toolchains do not ship their own auxilliary utilities such as archivers  and
       linkers.   The compiler driver may support a command-line argument to specify the location
       of such tools.  CMAKE_<LANG>_COMPILER_EXTERNAL_TOOLCHAIN may be set to a path to a path to
       the external toolchain and will be passed to the compiler driver if supported.

       variable.

   CMAKE_<LANG>_COMPILER_TARGET
       The target for cross-compiling, if supported.

       Some compiler drivers are inherently cross-compilers, such as clang  and  QNX  qcc.  These
       compiler  drivers  support  a command-line argument to specify the target to cross-compile
       for.

       This variable may only be set in a toolchain file specified  by  the  CMAKE_TOOLCHAIN_FILE
       variable.

   CMAKE_<LANG>_COMPILER_VERSION

       GHS kernel flags for RelWithDebInfo type or configuration.

       <LANG> flags used when CMAKE_BUILD_TYPE is RelWithDebInfo (short for  Release  With  Debug
       Information).

   CMAKE_<LANG>_IGNORE_EXTENSIONS
       File extensions that should be ignored by the build.

       This  is  a list of file extensions that may be part of a project for a given language but
       are not compiled.

   CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES
       Directories implicitly searched by the compiler for header files.

       CMake does not explicitly specify these directories on compiler command lines for language
       <LANG>.   This  prevents  system  include  directories  from being treated as user include
       directories on some compilers.

   CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES
       Implicit linker search path detected for language <LANG>.

       Compilers typically pass directories containing language  runtime  libraries  and  default
       library  search  paths  when they invoke a linker.  These paths are implicit linker search
       directories for the compiler's language.  CMake automatically  detects  these  directories
       for each language and reports the results in this variable.

       When   a   library   in   one   of   these   directories   is   given   by  full  path  to
       target_link_libraries() CMake will generate the -l<name> form on link lines to ensure  the
       linker  searches its implicit directories for the library.  Note that some toolchains read
       implicit directories from an environment variable such as LIBRARY_PATH so keep  its  value
       consistent when operating in a given build tree.

   CMAKE_<LANG>_IMPLICIT_LINK_FRAMEWORK_DIRECTORIES
       Implicit linker framework search path detected for language <LANG>.

       These  paths are implicit linker framework search directories for the compiler's language.
       CMake automatically detects these directories for each language and reports the results in
       this variable.

   CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
       Implicit link libraries and flags detected for language <LANG>.

       Compilers typically pass language runtime library names and other flags when they invoke a
       linker.  These flags are  implicit  link  options  for  the  compiler's  language.   CMake
       automatically  detects these libraries and flags for each language and reports the results
       in this variable.

   CMAKE_<LANG>_LIBRARY_ARCHITECTURE
       Target architecture library directory name detected for <LANG>.

       If the <LANG> compiler passes to the linker an architecture-specific system library search
       directory  such  as  <prefix>/lib/<arch>  this  variable  contains  the  <arch> name if/as
       detected by CMake.

   CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES
       True if CMAKE_<LANG>_LINKER_PREFERENCE propagates across targets.

       This is used when CMake selects a  linker  language  for  a  target.   Languages  compiled
       directly into the target are always considered.  A language compiled into static libraries
       linked by the target is considered if this variable is true.

   CMAKE_<LANG>_LINKER_PREFERENCE
       Preference value for linker language selection.

       The "linker language" for executable, shared library, and module targets is  the  language
       whose  compiler  will  invoke  the  linker.   The LINKER_LANGUAGE target property sets the
       language explicitly.  Otherwise, the linker language is that whose linker preference value
       is   highest  among  languages  compiled  and  linked  into  the  target.   See  also  the
       CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES variable.

   CMAKE_<LANG>_LINK_EXECUTABLE
       Rule variable to link an executable.

       Rule variable to link an executable for the given language.

   CMAKE_<LANG>_OUTPUT_EXTENSION
       Extension for the output of a compile for a single file.

       This is the extension for an object file for the given <LANG>.  For example .obj for C  on
       Windows.

   CMAKE_<LANG>_PLATFORM_ID
       An internal variable subject to change.

       This is used in determining the platform and is subject to change.

   CMAKE_<LANG>_SIMULATE_ID
       Identification string of "simulated" compiler.

       Some  compilers  simulate  other  compilers  to serve as drop-in replacements.  When CMake
       detects  such  a  compiler  it  sets  this  variable  to  what   would   have   been   the
       CMAKE_<LANG>_COMPILER_ID for the simulated compiler.

   CMAKE_<LANG>_SIMULATE_VERSION
       Version string of "simulated" compiler.

       Some  compilers  simulate  other  compilers  to serve as drop-in replacements.  When CMake
       detects  such  a  compiler  it  sets  this  variable  to  what   would   have   been   the
       CMAKE_<LANG>_COMPILER_VERSION for the simulated compiler.

   CMAKE_<LANG>_SIZEOF_DATA_PTR
       Size of pointer-to-data types for language <LANG>.

       This holds the size (in bytes) of pointer-to-data types in the target platform ABI.  It is
       defined for languages C and CXX (C++).

   CMAKE_<LANG>_SOURCE_FILE_EXTENSIONS
       Extensions of source files for the given language.

       This is the list of extensions for a given language's source files.

   CMAKE_USER_MAKE_RULES_OVERRIDE_<LANG>
       Specify a CMake file that overrides platform information for <LANG>.

       This is a language-specific version of  CMAKE_USER_MAKE_RULES_OVERRIDE  loaded  only  when
       enabling language <LANG>.

VARIABLES FOR CTEST

   CTEST_BINARY_DIRECTORY
       Specify the CTest BuildDirectory setting in a ctest(1) dashboard client script.

   CTEST_BUILD_COMMAND
       Specify the CTest MakeCommand setting in a ctest(1) dashboard client script.

   CTEST_BUILD_NAME
       Specify the CTest BuildName setting in a ctest(1) dashboard client script.

   CTEST_BZR_COMMAND
       Specify the CTest BZRCommand setting in a ctest(1) dashboard client script.

   CTEST_BZR_UPDATE_OPTIONS
       Specify the CTest BZRUpdateOptions setting in a ctest(1) dashboard client script.

   CTEST_CHANGE_ID
       Specify the CTest ChangeId setting in a ctest(1) dashboard client script.

       This setting allows CTest to pass arbitrary information about this build up to CDash.  One
       use of this feature is to allow CDash to post comments on your pull  request  if  anything
       goes wrong with your build.

   CTEST_CHECKOUT_COMMAND
       Tell  the  ctest_start()  command  how to checkout or initialize the source directory in a
       ctest(1) dashboard client script.

   CTEST_CONFIGURATION_TYPE
       Specify the CTest DefaultCTestConfigurationType setting in  a  ctest(1)  dashboard  client
       script.

   CTEST_CONFIGURE_COMMAND
       Specify the CTest ConfigureCommand setting in a ctest(1) dashboard client script.

   CTEST_COVERAGE_COMMAND
       Specify the CTest CoverageCommand setting in a ctest(1) dashboard client script.

   Cobertura
       Using  Cobertura  as  the  coverage  generation  within your multi-module Java project can
       generate a series of XML files.

       The Cobertura Coverage parser expects to read the coverage data from  a  single  XML  file
       which  contains  the  coverage  data  for  all  modules.  Cobertura has a program with the
       ability to merge given cobertura.ser files and then another program to generate a combined
       XML  file  from  the  previous merged file.  For command line testing, this can be done by
       hand prior  to  CTest  looking  for  the  coverage  files.  For  script  builds,  set  the
       CTEST_COVERAGE_COMMAND  variable  to  point to a file which will perform these same steps,
       such as a .sh or .bat file.

          set(CTEST_COVERAGE_COMMAND .../run-coverage-and-consolidate.sh)

       where   the   run-coverage-and-consolidate.sh   script   is   perhaps   created   by   the
       configure_file() command and might contain the following code:

          #!/usr/bin/env bash
          CoberturaFiles="$(find "/path/to/source" -name "cobertura.ser")"
          SourceDirs="$(find "/path/to/source" -name "java" -type d)"
          cobertura-merge --datafile coberturamerge.ser $CoberturaFiles
          cobertura-report --datafile coberturamerge.ser --destination . \
                           --format xml $SourceDirs

       The  script  uses  find to capture the paths to all of the cobertura.ser files found below
       the project's source directory.  It keeps the list of files and supplies it as an argument
       to  the cobertura-merge program. The --datafile argument signifies where the result of the
       merge will be kept.

       The combined coberturamerge.ser file is then used to generate the  XML  report  using  the
       cobertura-report  program.   The  call to the cobertura-report program requires some named
       arguments.

       --datafila
              path to the merged .ser file

       --destination
              path to put the output files(s)

       --format
              file format to write output in: xml or html

       The rest of the supplied arguments  consist  of  the  full  paths  to  the  /src/main/java
       directories  of each module within the souce tree. These directories are needed and should
       not be forgotten.

   CTEST_COVERAGE_EXTRA_FLAGS
       Specify the CTest CoverageExtraFlags setting in a ctest(1) dashboard client script.

   CTEST_CURL_OPTIONS
       Specify the CTest CurlOptions setting in a ctest(1) dashboard client script.

VARIABLES FOR CPACK

CPACK_ABSOLUTE_DESTINATION_FILES
List of files which have been installed using an ABSOLUTE DESTINATION path.

This variable is a Read-Only variable which is set internally by CPack during installation
and before packaging using CMAKE_ABSOLUTE_DESTINATION_FILES defined in cmake_install.cmake
scripts. The value can be used within CPack project configuration file and/or
CPack<GEN>.cmake file of <GEN> generator.

CPACK_COMPONENT_INCLUDE_TOPLEVEL_DIRECTORY
Boolean toggle to include/exclude top level directory (component case).

Similar usage as CPACK_INCLUDE_TOPLEVEL_DIRECTORY but for the component case. See
CPACK_INCLUDE_TOPLEVEL_DIRECTORY documentation for the detail.

CPACK_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
Ask CPack to error out as soon as a file with absolute INSTALL DESTINATION is encountered.

The fatal error is emitted before the installation of the offending file takes place.
Some CPack generators, like NSIS, enforce this internally. This variable triggers the
definition of CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION when CPack runs.

CPACK_INCLUDE_TOPLEVEL_DIRECTORY
Boolean toggle to include/exclude top level directory.

When preparing a package CPack installs the item under the so-called top level directory.
The purpose of is to include (set to 1 or ON or TRUE) the top level directory in the
package or not (set to 0 or OFF or FALSE).

Each CPack generator has a built-in default value for this variable. E.g. Archive
generators (ZIP, TGZ, ...) includes the top level whereas RPM or DEB don't. The user may
override the default value by setting this variable.

There is a similar variable CPACK_COMPONENT_INCLUDE_TOPLEVEL_DIRECTORY which may be used
to override the behavior for the component packaging case which may have different default
value for historical (now backward compatibility) reason.

CPACK_INSTALL_SCRIPT
Extra CMake script provided by the user.

If set this CMake script will be executed by CPack during its local [CPack-private]
installation which is done right before packaging the files. The script is not called by
e.g.: make install.

CPACK_PACKAGING_INSTALL_PREFIX
The prefix used in the built package.

Each CPack generator has a default value (like /usr). This default value may be
overwritten from the CMakeLists.txt or the cpack(1) command line by setting an alternative
value. Example:

set(CPACK_PACKAGING_INSTALL_PREFIX "/opt")

This is not the same purpose as CMAKE_INSTALL_PREFIX which is used when installing from
the build tree without building a package.

CPACK_SET_DESTDIR
Boolean toggle to make CPack use DESTDIR mechanism when packaging.

DESTDIR means DESTination DIRectory. It is commonly used by makefile users in order to
install software at non-default location. It is a basic relocation mechanism that should
not be used on Windows (see CMAKE_INSTALL_PREFIX documentation). It is usually invoked
like this:

make DESTDIR=/home/john install

which will install the concerned software using the installation prefix, e.g. /usr/local
prepended with the DESTDIR value which finally gives /home/john/usr/local. When preparing
a package, CPack first installs the items to be packaged in a local (to the build tree)
directory by using the same DESTDIR mechanism. Nevertheless, if CPACK_SET_DESTDIR is set
then CPack will set DESTDIR before doing the local install. The most noticeable
difference is that without CPACK_SET_DESTDIR, CPack uses CPACK_PACKAGING_INSTALL_PREFIX as
a prefix whereas with CPACK_SET_DESTDIR set, CPack will use CMAKE_INSTALL_PREFIX as a
prefix.

Manually setting CPACK_SET_DESTDIR may help (or simply be necessary) if some install rules
uses absolute DESTINATION (see CMake install() command). However, starting with
CPack/CMake 2.8.3 RPM and DEB installers tries to handle DESTDIR automatically so that it
is seldom necessary for the user to set it.

CPACK_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
Ask CPack to warn each time a file with absolute INSTALL DESTINATION is encountered.

This variable triggers the definition of CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION when
CPack runs cmake_install.cmake scripts.
