NAME
cpack - Packaging driver provided by CMake.
USAGE
cpack -G <generator> [options]
DESCRIPTION
The "cpack" executable is the CMake packaging program. CMake-generated build trees created for projects
that use the INSTALL_* commands have packaging support. This program will generate the package.
CMake is a cross-platform build system generator. Projects specify their build process with
platform-independent CMake listfiles included in each directory of a source tree with the name
CMakeLists.txt. Users build a project by using CMake to generate a build system for a native tool on
their platform.
OPTIONS
-G <generator>
Use the specified generator to generate package.
CPack may support multiple native packaging systems on certain platforms. A generator is
responsible for generating input files for particular system and invoking that systems. Possible
generator names are specified in the Generators section.
-C <Configuration>
Specify the project configuration
This option specifies the configuration that the project was build with, for example 'Debug',
'Release'.
-D <var>=<value>
Set a CPack variable.
Set a variable that can be used by the generator.
--config <config file>
Specify the config file.
Specify the config file to use to create the package. By default CPackConfig.cmake in the current
directory will be used.
--verbose,-V
enable verbose output
Run cpack with verbose output.
--debug
enable debug output (for CPack developers)
Run cpack with debug output (for CPack developers).
-P <package name>
override/define CPACK_PACKAGE_NAME
If the package name is not specified on cpack commmand line thenCPack.cmake defines it as
CMAKE_PROJECT_NAME
-R <package version>
override/define CPACK_PACKAGE_VERSION
If version is not specified on cpack command line thenCPack.cmake defines it from
CPACK_PACKAGE_VERSION_[MAJOR|MINOR|PATCH]look into CPack.cmake for detail
-B <package directory>
override/define CPACK_PACKAGE_DIRECTORY
The directory where CPack will be doing its packaging work.The resulting package will be found
there. Inside this directoryCPack creates '_CPack_Packages' sub-directory which is theCPack
temporary directory.
--vendor <vendor name>
override/define CPACK_PACKAGE_VENDOR
If vendor is not specified on cpack command line (or inside CMakeLists.txt) thenCPack.cmake
defines it with a default value

COMMANDS
cpack_add_component
Describes a CPack installation component named by the COMPONENT argument to a CMake INSTALL
command.
cpack_add_component(compname
[DISPLAY_NAME name]
[DESCRIPTION description]
[HIDDEN | REQUIRED | DISABLED ]
[GROUP group]
[DEPENDS comp1 comp2 ... ]
[INSTALL_TYPES type1 type2 ... ]
[DOWNLOADED]
[ARCHIVE_FILE filename])
The cmake_add_component command describes an installation component, which the user can opt to
install or remove as part of the graphical installation process. compname is the name of the
component, as provided to the COMPONENT argument of one or more CMake INSTALL commands.
DISPLAY_NAME is the displayed name of the component, used in graphical installers to display the
component name. This value can be any string.
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 "\n"
as the line separator. Typically, these descriptions should be no more than a few lines long.
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.
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).
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.
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.
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.
INSTALL_TYPES lists the installation types of which this component is a part. When one of these
installations types is selected, this component will automatically be selected. Installation types
are described with the cpack_add_install_type command, detailed below.
DOWNLOADED indicates that this component should be downloaded on-the-fly by the installer, rather
than packaged in with the installer itself. For more information, see the
cpack_configure_downloads command.
ARCHIVE_FILE provides a name for the archive file created by CPack to be used for downloaded
components. If not supplied, CPack will create a file with some name based on
CPACK_PACKAGE_FILE_NAME and the name of the component. See cpack_configure_downloads for more
information.
cpack_add_component_group
Describes a group of related CPack installation components.
cpack_add_component_group(groupname
[DISPLAY_NAME name]
[DESCRIPTION description]
[PARENT_GROUP parent]
[EXPANDED]
[BOLD_TITLE])
The cpack_add_component_group describes a group of installation components, which will be placed
together within the listing of options. Typically, component groups allow the user to
select/deselect all of the components within a single group via a single group-level option. Use
component groups to reduce the complexity of installers with many options. groupname is an
arbitrary name used to identify the group in the GROUP argument of the cpack_add_component
command, which is used to place a component in a group. The name of the group must not conflict
with the name of any component.
DISPLAY_NAME is the displayed name of the component group, used in graphical installers to display
the component group name. This value can be any string.
DESCRIPTION is an extended description of the component group, used in graphical installers to
give the user additional information about the components within that group. Descriptions can span
multiple lines using "\n" as the line separator. Typically, these descriptions should be no more
than a few lines long.
PARENT_GROUP, if supplied, names the parent group of this group. Parent groups are used to
establish a hierarchy of groups, providing an arbitrary hierarchy of groups.
EXPANDED indicates that, by default, the group should show up as "expanded", so that the user
immediately sees all of the components within the group. Otherwise, the group will initially show
up as a single entry.
BOLD_TITLE indicates that the group title should appear in bold, to call the user's attention to
the group.
cpack_add_install_type
Add a new installation type containing a set of predefined component selections to the graphical
installer.
cpack_add_install_type(typename
[DISPLAY_NAME name])
The cpack_add_install_type command identifies a set of preselected components that represents a
common use case for an application. For example, a "Developer" install type might include an
application along with its header and library files, while an "End user" install type might just
include the application's executable. Each component identifies itself with one or more install
types via the INSTALL_TYPES argument to cpack_add_component.
DISPLAY_NAME is the displayed name of the install type, which will typically show up in a
drop-down box within a graphical installer. This value can be any string.
cpack_configure_downloads
Configure CPack to download selected components on-the-fly as part of the installation process.
cpack_configure_downloads(site
[UPLOAD_DIRECTORY dirname]
[ALL]
[ADD_REMOVE|NO_ADD_REMOVE])
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 requires the ZipDLL plug-in for
NSIS, available at:
http://nsis.sourceforge.net/ZipDLL_plug-in
On Mac OS X, installers that download components on-the-fly can only be built and installed on
system using Mac OS X 10.5 or later.
The site argument is a URL where the archives for downloadable components will reside, e.g.,
http://www.cmake.org/files/2.6.1/installer/ All of the archives produced by CPack should be
uploaded to that location.
UPLOAD_DIRECTORY is the local directory where CPack will create the various archives for each of
the components. The contents of this directory should be uploaded to a location accessible by the
URL given in the site argument. If omitted, CPack will use the directory CPackUploads inside the
CMake binary directory to store the generated archives.
The ALL flag indicates that all components be downloaded. Otherwise, only those components
explicitly marked as DOWNLOADED or that have a specified ARCHIVE_FILE will be downloaded.
Additionally, the ALL option implies ADD_REMOVE (unless NO_ADD_REMOVE is specified).
ADD_REMOVE indicates that CPack should install a copy of the installer that can be called from
Windows' Add/Remove Programs dialog (via the "Modify" button) to change the set of installed
components. NO_ADD_REMOVE turns off this behavior. This option is ignored on Mac OS X.
break Break from an enclosing foreach or while loop.
break()

cmake_host_system_information
Query host system specific information.
cmake_host_system_information(RESULT <variable> QUERY <key> ...)
Queries system information of the host system on which cmake runs. One or more <key> can be
provided to select the information to be queried. The list of queried values is stored in
<variable>.
<key> can be one of the following values:
NUMBER_OF_LOGICAL_CORES = Number of logical cores.
NUMBER_OF_PHYSICAL_CORES = Number of physical cores.
HOSTNAME = Hostname.
FQDN = Fully qualified domain name.
TOTAL_VIRTUAL_MEMORY = Total virtual memory in megabytes.
AVAILABLE_VIRTUAL_MEMORY = Available virtual memory in megabytes.
TOTAL_PHYSICAL_MEMORY = Total physical memory in megabytes.
AVAILABLE_PHYSICAL_MEMORY = Available physical memory in megabytes.
cmake_minimum_required
Set the minimum required version of cmake for a project.
cmake_minimum_required(VERSION major[.minor[.patch[.tweak]]]
[FATAL_ERROR])
If the current version of CMake is lower than that required it will stop processing the project
and report an error. When a version higher than 2.4 is specified the command implicitly invokes
cmake_policy(VERSION major[.minor[.patch[.tweak]]])
which sets the cmake policy version level to the version specified. When version 2.4 or lower is
given the command implicitly invokes
cmake_policy(VERSION 2.4)
which enables compatibility features for CMake 2.4 and lower.
The FATAL_ERROR option is accepted but ignored by CMake 2.6 and higher. It should be specified so
CMake versions 2.4 and lower fail with an error instead of just a warning.
cmake_policy
Manage CMake Policy settings.
As CMake evolves it is sometimes necessary to change existing behavior in order to fix bugs or
improve implementations of existing features. The CMake Policy mechanism is designed to help keep
existing projects building as new versions of CMake introduce changes in behavior. Each new
policy (behavioral change) is given an identifier of the form "CMP<NNNN>" where "<NNNN>" is an
integer index. Documentation associated with each policy describes the OLD and NEW behavior and
the reason the policy was introduced. Projects may set each policy to select the desired
behavior. When CMake needs to know which behavior to use it checks for a setting specified by the
project. If no setting is available the OLD behavior is assumed and a warning is produced
requesting that the policy be set.
The cmake_policy command is used to set policies to OLD or NEW behavior. While setting policies
individually is supported, we encourage projects to set policies based on CMake versions.
cmake_policy(VERSION major.minor[.patch[.tweak]])
Specify that the current CMake list file is written for the given version of CMake. All policies
introduced in the specified version or earlier will be set to use NEW behavior. All policies
introduced after the specified version will be unset (unless variable
CMAKE_POLICY_DEFAULT_CMP<NNNN> sets a default). This effectively requests behavior preferred as
of a given CMake version and tells newer CMake versions to warn about their new policies. The
policy version specified must be at least 2.4 or the command will report an error. In order to
get compatibility features supporting versions earlier than 2.4 see documentation of policy
CMP0001.
cmake_policy(SET CMP<NNNN> NEW)
cmake_policy(SET CMP<NNNN> OLD)
Tell CMake to use the OLD or NEW behavior for a given policy. Projects depending on the old
behavior of a given policy may silence a policy warning by setting the policy state to OLD.
Alternatively one may fix the project to work with the new behavior and set the policy state to
NEW.
cmake_policy(GET CMP<NNNN> <variable>)
Check whether a given policy is set to OLD or NEW behavior. The output variable value will be
"OLD" or "NEW" if the policy is set, and empty otherwise.
CMake keeps policy settings on a stack, so changes made by the cmake_policy command affect only
the top of the stack. A new entry on the policy stack is managed automatically for each
subdirectory to protect its parents and siblings. CMake also manages a new entry for scripts
loaded by include() and find_package() commands except when invoked with the NO_POLICY_SCOPE
option (see also policy CMP0011). The cmake_policy command provides an interface to manage custom
entries on the policy stack:
cmake_policy(PUSH)
cmake_policy(POP)
Each PUSH must have a matching POP to erase any changes. This is useful to make temporary changes
to policy settings.
Functions and macros record policy settings when they are created and use the pre-record policies
when they are invoked. If the function or macro implementation sets policies, the changes
automatically propagate up through callers until they reach the closest nested policy stack entry.
configure_file
Copy a file to another location and modify its contents.
configure_file(<input> <output>
[COPYONLY] [ESCAPE_QUOTES] [@ONLY]
[NEWLINE_STYLE [UNIX|DOS|WIN32|LF|CRLF] ])
Copies a file <input> to file <output> and substitutes variable values referenced in the file
content. If <input> is a relative path it is evaluated with respect to the current source
directory. The <input> must be a file, not a directory. If <output> is a relative path it is
evaluated with respect to the current binary directory. If <output> names an existing directory
the input file is placed in that directory with its original name.
If the <input> file is modified the build system will re-run CMake to re-configure the file and
generate the build system again.
This command replaces any variables in the input file referenced as ${VAR} or @VAR@ with their
values as determined by CMake. If a variable is not defined, it will be replaced with nothing.
If COPYONLY is specified, then no variable expansion will take place. If ESCAPE_QUOTES is
specified then any substituted quotes will be C-style escaped. The file will be configured with
the current values of CMake variables. If @ONLY is specified, only variables of the form @VAR@
will be replaced and ${VAR} will be ignored. This is useful for configuring scripts that use
${VAR}.
Input file lines of the form "#cmakedefine VAR ..." will be replaced with either "#define VAR ..."
or "/* #undef VAR */" depending on whether VAR is set in CMake to any value not considered a false
constant by the if() command. (Content of "...", if any, is processed as above.) Input file lines
of the form "#cmakedefine01 VAR" will be replaced with either "#define VAR 1" or "#define VAR 0"
similarly.
With NEWLINE_STYLE the line ending could be adjusted:
'UNIX' or 'LF' for \n, 'DOS', 'WIN32' or 'CRLF' for \r\n.
COPYONLY must not be used with NEWLINE_STYLE.

execute_process
Execute one or more child processes.
execute_process(COMMAND <cmd1> [args1...]]
[COMMAND <cmd2> [args2...] [...]]
[WORKING_DIRECTORY <directory>]
[TIMEOUT <seconds>]
[RESULT_VARIABLE <variable>]

[OUTPUT_FILE <file>]
[ERROR_FILE <file>]
[OUTPUT_QUIET]
[ERROR_QUIET]
[OUTPUT_STRIP_TRAILING_WHITESPACE]
[ERROR_STRIP_TRAILING_WHITESPACE])
Runs the given sequence of one or more commands with the standard output of each process piped to
the standard input of the next. A single standard error pipe is used for all processes. If
WORKING_DIRECTORY is given the named directory will be set as the current working directory of the
child processes. If TIMEOUT is given the child processes will be terminated if they do not finish
in the specified number of seconds (fractions are allowed). If RESULT_VARIABLE is given the
variable will be set to contain the result of running the processes. This will be an integer
return code from the last child or a string describing an error condition. If OUTPUT_VARIABLE or
ERROR_VARIABLE are given the variable named will be set with the contents of the standard output
and standard error pipes respectively. If the same variable is named for both pipes their output
will be merged in the order produced. If INPUT_FILE, OUTPUT_FILE, or ERROR_FILE is given the file
named will be attached to the standard input of the first process, standard output of the last
process, or standard error of all processes respectively. If OUTPUT_QUIET or ERROR_QUIET is given
then the standard output or standard error results will be quietly ignored. If more than one
OUTPUT_* or ERROR_* option is given for the same pipe the precedence is not specified. If no
OUTPUT_* or ERROR_* options are given the output will be shared with the corresponding pipes of
the CMake process itself.
The execute_process command is a newer more powerful version of exec_program, but the old command
has been kept for compatibility.

WRITE will write a message into a file called 'filename'. It overwrites the file if it already
exists, and creates the file if it does not exist. (If the file is a build input, use
configure_file to update the file only when its content changes.)
APPEND will write a message into a file same as WRITE, except it will append it to the end of the
file
READ will read the content of a file and store it into the variable. It will start at the given
offset and read up to numBytes. If the argument HEX is given, the binary data will be converted to
hexadecimal representation and this will be stored in the variable.
MD5, SHA1, SHA224, SHA256, SHA384, and SHA512 will compute a cryptographic hash of the content of
a file.
STRINGS will parse a list of ASCII strings from a file and store it in a variable. Binary data in
the file are ignored. Carriage return (CR) characters are ignored. It works also for Intel Hex and
Motorola S-record files, which are automatically converted to binary format when reading them.
Disable this using NO_HEX_CONVERSION.
LIMIT_COUNT sets the maximum number of strings to return. LIMIT_INPUT sets the maximum number of
bytes to read from the input file. LIMIT_OUTPUT sets the maximum number of bytes to store in the
output variable. LENGTH_MINIMUM sets the minimum length of a string to return. Shorter strings are
ignored. LENGTH_MAXIMUM sets the maximum length of a string to return. Longer strings are split
into strings no longer than the maximum length. NEWLINE_CONSUME allows newlines to be included in
strings instead of terminating them.
REGEX specifies a regular expression that a string must match to be returned. Typical usage
file(STRINGS myfile.txt myfile)
stores a list in the variable "myfile" in which each item is a line from the input file.
GLOB will generate a list of all files that match the globbing expressions and store it into the
variable. Globbing expressions are similar to regular expressions, but much simpler. If RELATIVE
flag is specified for an expression, the results will be returned as a relative path to the given
path. (We do not recommend using GLOB to collect a list of source files from your source tree.
If no CMakeLists.txt file changes when a source is added or removed then the generated build
system cannot know when to ask CMake to regenerate.)
Examples of globbing expressions include:
*.cxx - match all files with extension cxx
*.vt? - match all files with extension vta,...,vtz
f[3-5].txt - match files f3.txt, f4.txt, f5.txt
GLOB_RECURSE will generate a list similar to the regular GLOB, except it will traverse all the
subdirectories of the matched directory and match the files. Subdirectories that are symlinks are
only traversed if FOLLOW_SYMLINKS is given or cmake policy CMP0009 is not set to NEW. See cmake
--help-policy CMP0009 for more information.
Examples of recursive globbing include:
/dir/*.py - match all python files in /dir and subdirectories
MAKE_DIRECTORY will create the given directories, also if their parent directories don't exist yet
RENAME moves a file or directory within a filesystem, replacing the destination atomically.
REMOVE will remove the given files, also in subdirectories
REMOVE_RECURSE will remove the given files and directories, also non-empty directories
RELATIVE_PATH will determine relative path from directory to the given file.
TO_CMAKE_PATH will convert path into a cmake style path with unix /. The input can be a single
path or a system path like "$ENV{PATH}". Note the double quotes around the ENV call TO_CMAKE_PATH
only takes one argument. This command will also convert the native list delimiters for a list of
paths like the PATH environment variable.
TO_NATIVE_PATH works just like TO_CMAKE_PATH, but will convert from a cmake style path into the
native path style \ for windows and / for UNIX.
DOWNLOAD will download the given URL to the given file. If LOG var is specified a log of the
download will be put in var. If STATUS var is specified the status of the operation will be put in
var. The status is returned in a list of length 2. The first element is the numeric return value
for the operation, and the second element is a string value for the error. A 0 numeric error means
no error in the operation. If TIMEOUT time is specified, the operation will timeout after time
seconds, time should be specified as an integer. The INACTIVITY_TIMEOUT specifies an integer
number of seconds of inactivity after which the operation should terminate. If EXPECTED_HASH
ALGO=value is specified, the operation will verify that the downloaded file's actual hash matches
the expected value, where ALGO is one of MD5, SHA1, SHA224, SHA256, SHA384, or SHA512. If it does
not match, the operation fails with an error. ("EXPECTED_MD5 sum" is short-hand for "EXPECTED_HASH
MD5=sum".) If SHOW_PROGRESS is specified, progress information will be printed as status messages
until the operation is complete. For https URLs CMake must be built with OpenSSL. TLS/SSL
certificates are not checked by default. Set TLS_VERIFY to ON to check certificates and/or use
EXPECTED_HASH to verify downloaded content. Set TLS_CAINFO to specify a custom Certificate
Authority file. If either TLS option is not given CMake will check variables CMAKE_TLS_VERIFY and
CMAKE_TLS_CAINFO, respectively.
UPLOAD will upload the given file to the given URL. If LOG var is specified a log of the upload
will be put in var. If STATUS var is specified the status of the operation will be put in var. The
status is returned in a list of length 2. The first element is the numeric return value for the
operation, and the second element is a string value for the error. A 0 numeric error means no
error in the operation. If TIMEOUT time is specified, the operation will timeout after time
seconds, time should be specified as an integer. The INACTIVITY_TIMEOUT specifies an integer
number of seconds of inactivity after which the operation should terminate. If SHOW_PROGRESS is
specified, progress information will be printed as status messages until the operation is
complete.
TIMESTAMP will write a string representation of the modification time of filename to variable.
Should the command be unable to obtain a timestamp variable will be set to the empty string "".
See documentation of the string TIMESTAMP sub-command for more details.
The file() command also provides COPY and INSTALL signatures:
file(<COPY|INSTALL> files... DESTINATION <dir>
[FILE_PERMISSIONS permissions...]
[DIRECTORY_PERMISSIONS permissions...]
[NO_SOURCE_PERMISSIONS] [USE_SOURCE_PERMISSIONS]
[FILES_MATCHING]
[[PATTERN <pattern> | REGEX <regex>]
[EXCLUDE] [PERMISSIONS permissions...]] [...])
The COPY signature copies files, directories, and symlinks to a destination folder. Relative
input paths are evaluated with respect to the current source directory, and a relative destination
is evaluated with respect to the current build directory. Copying preserves input file
timestamps, and optimizes out a file if it exists at the destination with the same timestamp.
Copying preserves input permissions unless explicit permissions or NO_SOURCE_PERMISSIONS are given
(default is USE_SOURCE_PERMISSIONS). See the install(DIRECTORY) command for documentation of
permissions, PATTERN, REGEX, and EXCLUDE options.
The INSTALL signature differs slightly from COPY: it prints status messages, and
NO_SOURCE_PERMISSIONS is default. Installation scripts generated by the install() command use
this signature (with some undocumented options for internal use).
GENERATE will write an <output_file> with content from an <input_file>, or from <input_content>.
The output is generated conditionally based on the content of the <condition>. The file is
written at CMake generate-time and the input may contain generator expressions. The <condition>,
<output_file> and <input_file> may also contain generator expressions. The <condition> must
evaluate to either '0' or '1'. The <output_file> must evaluate to a unique name among all
configurations and among all invocations of file(GENERATE).
find_file
Find the full path to a file.
find_file(<VAR> name1 [path1 path2 ...])
This is the short-hand signature for the command that is sufficient in many cases. It is the same
as find_file(<VAR> name1 [PATHS path1 path2 ...])
find_file(
<VAR>
name | NAMES name1 [name2 ...]
[HINTS path1 [path2 ... ENV var]]
[PATHS path1 [path2 ... ENV var]]
[PATH_SUFFIXES suffix1 [suffix2 ...]]
[DOC "cache documentation string"]

This command is used to find a full path to named file. A cache entry named by <VAR> is created to
store the result of this command. If the full path to a file is found the result is stored in the
variable and the search will not be repeated unless the variable is cleared. If nothing is found,
the result will be <VAR>-NOTFOUND, and the search will be attempted again the next time find_file
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 the NAMES argument. Additional search locations can be
specified after the PATHS argument. If ENV var is found in the HINTS or PATHS section the
environment variable var will be read and converted from a system environment variable to a cmake
style list of paths. For example ENV PATH would be a way to list the system path variable. The
argument after DOC will be used for the documentation string in the cache. PATH_SUFFIXES
specifies additional subdirectories to check below each search path.
If NO_DEFAULT_PATH is specified, then no additional paths are added to the search. If
NO_DEFAULT_PATH is not specified, the search process is as follows:
1. Search paths specified in cmake-specific cache variables. These are intended to be used on the
command line with a -DVAR=value. This can be skipped if NO_CMAKE_PATH is passed.
<prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
<prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_INCLUDE_PATH
CMAKE_FRAMEWORK_PATH
2. Search paths specified in cmake-specific environment variables. These are intended to be set
in the user's shell configuration. This can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
<prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
<prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_INCLUDE_PATH
CMAKE_FRAMEWORK_PATH
3. Search the paths specified by the HINTS option. These should be paths computed by system
introspection, such as a hint provided by the location of another item already found. Hard-coded
guesses should be specified with the PATHS option.
4. Search the standard system environment variables. This can be skipped if
NO_SYSTEM_ENVIRONMENT_PATH is an argument.
PATH
INCLUDE
5. Search cmake variables defined in the Platform files for the current system. This can be
skipped if NO_CMAKE_SYSTEM_PATH is passed.
<prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
<prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
CMAKE_SYSTEM_INCLUDE_PATH
CMAKE_SYSTEM_FRAMEWORK_PATH
6. Search the paths specified by the PATHS option or in the short-hand version of the command.
These are typically hard-coded guesses.
On Darwin or systems supporting OS X Frameworks, the cmake variable CMAKE_FIND_FRAMEWORK 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.
On Darwin or systems supporting OS X Application Bundles, the cmake variable CMAKE_FIND_APPBUNDLE
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.
The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more directories to be prepended to all
other search directories. This effectively "re-roots" the entire search under given locations. By
default it is empty. It is especially useful when cross-compiling to point to the root directory
of the target environment and CMake will search there too. By default at first the directories
listed in CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be searched. The default
behavior can be adjusted by setting CMAKE_FIND_ROOT_PATH_MODE_INCLUDE. This behavior can be
manually overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH the search order will
be as described above. If NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
used. If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted directories will be searched.
The default search order is designed to be most-specific to least-specific for common use cases.
Projects may override the order by simply calling the command multiple times and using the NO_*
options:
find_file(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
find_file(<VAR> NAMES name)
Once one of the calls succeeds the result variable will be set and stored in the cache so that no
call will search again.
find_library
Find a library.
find_library(<VAR> name1 [path1 path2 ...])
This is the short-hand signature for the command that is sufficient in many cases. It is the same
as find_library(<VAR> name1 [PATHS path1 path2 ...])
find_library(
<VAR>
name | NAMES name1 [name2 ...] [NAMES_PER_DIR]

This command is used to find a library. A cache entry named by <VAR> is created to store the
result of this command. If the library is found the result is stored in the variable and the
search will not be repeated unless the variable is cleared. If nothing is found, the result will
be <VAR>-NOTFOUND, and the search will be attempted again the next time find_library is invoked
with the same variable. The name of the library that is searched for is specified by the names
listed after the NAMES argument. Additional search locations can be specified after the PATHS
argument. If ENV var is found in the HINTS or PATHS section the environment variable var will be
read and converted from a system environment variable to a cmake style list of paths. For example
ENV PATH would be a way to list the system path variable. The argument after DOC will be used for
the documentation string in the cache. PATH_SUFFIXES specifies additional subdirectories to check
below each search path.
If NO_DEFAULT_PATH is specified, then no additional paths are added to the search. If
NO_DEFAULT_PATH is not specified, the search process is as follows:

<prefix>/lib/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
<prefix>/lib for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_LIBRARY_PATH
CMAKE_FRAMEWORK_PATH

The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more directories to be prepended to all
other search directories. This effectively "re-roots" the entire search under given locations. By
default it is empty. It is especially useful when cross-compiling to point to the root directory
of the target environment and CMake will search there too. By default at first the directories
listed in CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be searched. The default
behavior can be adjusted by setting CMAKE_FIND_ROOT_PATH_MODE_LIBRARY. This behavior can be
manually overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH the search order will
be as described above. If NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be

The default search order is designed to be most-specific to least-specific for common use cases.
Projects may override the order by simply calling the command multiple times and using the NO_*
options:
find_library(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
find_library(<VAR> NAMES name)
Once one of the calls succeeds the result variable will be set and stored in the cache so that no
call will search again.
When more than one value is given to the NAMES option this command by default will consider one
name at a time and search every directory for it. The NAMES_PER_DIR option tells this command to
consider one directory at a time and search for all names in it.
If the library found is a framework, then VAR will be set to the full path to the framework
<fullPath>/A.framework. When a full path to a framework is used as a library, CMake will use a
-framework A, and a -F<fullPath> to link the framework to the target.
If the global property FIND_LIBRARY_USE_LIB64_PATHS is set all search paths will be tested as
normal, with "64/" appended, and with all matches of "lib/" replaced with "lib64/". This property
is automatically set for the platforms that are known to need it if at least one of the languages
supported by the PROJECT command is enabled.
find_package
Load settings for an external project.
find_package(<package> [version] [EXACT] [QUIET] [MODULE]
[REQUIRED] [[COMPONENTS] [components...]]
[OPTIONAL_COMPONENTS components...]
[NO_POLICY_SCOPE])
Finds and loads settings from an external project. <package>_FOUND will be set to indicate
whether the package was found. When the package is found package-specific information is provided
through variables and imported targets documented by the package itself. The QUIET option
disables messages if the package cannot be found. The MODULE option disables the second signature
documented below. The REQUIRED option stops processing with an error message if the package
cannot be found.
A package-specific list of required components may be listed after the COMPONENTS option (or after
the REQUIRED option if present). Additional optional components may be listed after
OPTIONAL_COMPONENTS. Available components and their influence on whether a package is considered
to be found are defined by the target package.
The [version] argument requests a version with which the package found should be compatible
(format is major[.minor[.patch[.tweak]]]). The EXACT option requests that the version be matched
exactly. If no [version] and/or component list is given to a recursive invocation inside a
find-module, the corresponding arguments are forwarded automatically from the outer call
(including the EXACT flag for [version]). Version support is currently provided only on a
package-by-package basis (details below).
User code should generally look for packages using the above simple signature. The remainder of
this command documentation specifies the full command signature and details of the search process.
Project maintainers wishing to provide a package to be found by this command are encouraged to
read on.
The command has two modes by which it searches for packages: "Module" mode and "Config" mode.
Module mode is available when the command is invoked with the above reduced signature. CMake
searches for a file called "Find<package>.cmake" in the CMAKE_MODULE_PATH followed by the CMake
installation. If the file is found, it is read and processed by CMake. It is responsible for
finding the package, checking the version, and producing any needed messages. Many find-modules
provide limited or no support for versioning; check the module documentation. If no module is
found and the MODULE option is not given the command proceeds to Config mode.
The complete Config mode command signature is:
find_package(<package> [version] [EXACT] [QUIET]
[REQUIRED] [[COMPONENTS] [components...]]
[CONFIG|NO_MODULE]
[NO_POLICY_SCOPE]
[NAMES name1 [name2 ...]]
[CONFIGS config1 [config2 ...]]
[HINTS path1 [path2 ... ]]
[PATHS path1 [path2 ... ]]
[PATH_SUFFIXES suffix1 [suffix2 ...]]
[NO_DEFAULT_PATH]
[NO_CMAKE_ENVIRONMENT_PATH]
[NO_CMAKE_PATH]
[NO_SYSTEM_ENVIRONMENT_PATH]
[NO_CMAKE_PACKAGE_REGISTRY]
[NO_CMAKE_BUILDS_PATH]
[NO_CMAKE_SYSTEM_PATH]
[NO_CMAKE_SYSTEM_PACKAGE_REGISTRY]
[CMAKE_FIND_ROOT_PATH_BOTH |
ONLY_CMAKE_FIND_ROOT_PATH |
NO_CMAKE_FIND_ROOT_PATH])
The CONFIG option may be used to skip Module mode explicitly and switch to Config mode. It is
synonymous to using NO_MODULE. Config mode is also implied by use of options not specified in the
reduced signature.
Config mode attempts to locate a configuration file provided by the package to be found. A cache
entry called <package>_DIR is created to hold the directory containing the file. By default the
command searches for a package with the name <package>. If the NAMES option is given the names
following it are used instead of <package>. The command searches for a file called
"<name>Config.cmake" or "<lower-case-name>-config.cmake" for each name specified. A replacement
set of possible configuration file names may be given using the CONFIGS option. The search
procedure is specified below. Once found, the configuration file is read and processed by CMake.
Since the file is provided by the package it already knows the location of package contents. The
full path to the configuration file is stored in the cmake variable <package>_CONFIG.
All configuration files which have been considered by CMake while searching for an installation of
the package with an appropriate version are stored in the cmake variable
<package>_CONSIDERED_CONFIGS, the associated versions in <package>_CONSIDERED_VERSIONS.
If the package configuration file cannot be found CMake will generate an error describing the
problem unless the QUIET argument is specified. If REQUIRED is specified and the package is not
found a fatal error is generated and the configure step stops executing. If <package>_DIR has
been set to a directory not containing a configuration file CMake will ignore it and search from
scratch.
When the [version] argument is given Config mode will only find a version of the package that
claims compatibility with the requested version (format is major[.minor[.patch[.tweak]]]). If the
EXACT option is given only a version of the package claiming an exact match of the requested
version may be found. CMake does not establish any convention for the meaning of version numbers.
Package version numbers are checked by "version" files provided by the packages themselves. For a
candidate package configuration file "<config-file>.cmake" the corresponding version file is
located next to it and named either "<config-file>-version.cmake" or "<config-file>Version.cmake".
If no such version file is available then the configuration file is assumed to not be compatible
with any requested version. A basic version file containing generic version matching code can be
created using the macro write_basic_package_version_file(), see its documentation for more
details. When a version file is found it is loaded to check the requested version number. The
version file is loaded in a nested scope in which the following variables have been defined:
PACKAGE_FIND_NAME = the <package> name
PACKAGE_FIND_VERSION = full requested version string
PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0
PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0
PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0
PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0
PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4
The version file checks whether it satisfies the requested version and sets these variables:
PACKAGE_VERSION = full provided version string
PACKAGE_VERSION_EXACT = true if version is exact match
PACKAGE_VERSION_COMPATIBLE = true if version is compatible
PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version
These variables are checked by the find_package command to determine whether the configuration
file provides an acceptable version. They are not available after the find_package call returns.
If the version is acceptable the following variables are set:
<package>_VERSION = full provided version string
<package>_VERSION_MAJOR = major version if provided, else 0
<package>_VERSION_MINOR = minor version if provided, else 0
<package>_VERSION_PATCH = patch version if provided, else 0
<package>_VERSION_TWEAK = tweak version if provided, else 0
<package>_VERSION_COUNT = number of version components, 0 to 4
and the corresponding package configuration file is loaded. When multiple package configuration
files are available whose version files claim compatibility with the version requested it is
unspecified which one is chosen. No attempt is made to choose a highest or closest version
number.
Config mode provides an elaborate interface and search procedure. Much of the interface is
provided for completeness and for use internally by find-modules loaded by Module mode. Most user
code should simply call
find_package(<package> [major[.minor]] [EXACT] [REQUIRED|QUIET])
in order to find a package. Package maintainers providing CMake package configuration files are
encouraged to name and install them such that the procedure outlined below will find them without
requiring use of additional options.
CMake constructs a set of possible installation prefixes for the package. Under each prefix
several directories are searched for a configuration file. The tables below show the directories
searched. Each entry is meant for installation trees following Windows (W), UNIX (U), or Apple
(A) conventions.
<prefix>/ (W)
<prefix>/(cmake|CMake)/ (W)
<prefix>/<name>*/ (W)
<prefix>/<name>*/(cmake|CMake)/ (W)
<prefix>/(lib/<arch>|lib|share)/cmake/<name>*/ (U)
<prefix>/(lib/<arch>|lib|share)/<name>*/ (U)
<prefix>/(lib/<arch>|lib|share)/<name>*/(cmake|CMake)/ (U)
On systems supporting OS X Frameworks and Application Bundles the following directories are
searched for frameworks or bundles containing a configuration file:
<prefix>/<name>.framework/Resources/ (A)
<prefix>/<name>.framework/Resources/CMake/ (A)
<prefix>/<name>.framework/Versions/*/Resources/ (A)
<prefix>/<name>.framework/Versions/*/Resources/CMake/ (A)
<prefix>/<name>.app/Contents/Resources/ (A)
<prefix>/<name>.app/Contents/Resources/CMake/ (A)
In all cases the <name> is treated as case-insensitive and corresponds to any of the names
specified (<package> or names given by NAMES). Paths with lib/<arch> are enabled if
CMAKE_LIBRARY_ARCHITECTURE is set. If PATH_SUFFIXES is specified the suffixes are appended to
each (W) or (U) directory entry one-by-one.
This set of directories is intended to work in cooperation with projects that provide
configuration files in their installation trees. Directories above marked with (W) are intended
for installations on Windows where the prefix may point at the top of an application's
installation directory. Those marked with (U) are intended for installations on UNIX platforms
where the prefix is shared by multiple packages. This is merely a convention, so all (W) and (U)
directories are still searched on all platforms. Directories marked with (A) are intended for
installations on Apple platforms. The cmake variables CMAKE_FIND_FRAMEWORK and
CMAKE_FIND_APPBUNDLE determine the order of preference as specified below.
The set of installation prefixes is constructed using the following steps. If NO_DEFAULT_PATH is
specified all NO_* options are enabled.
1. Search paths specified in cmake-specific cache variables. These are intended to be used on the
command line with a -DVAR=value. This can be skipped if NO_CMAKE_PATH is passed.
CMAKE_PREFIX_PATH
CMAKE_FRAMEWORK_PATH
CMAKE_APPBUNDLE_PATH
2. Search paths specified in cmake-specific environment variables. These are intended to be set
in the user's shell configuration. This can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
<package>_DIR
CMAKE_PREFIX_PATH
CMAKE_FRAMEWORK_PATH
CMAKE_APPBUNDLE_PATH
3. Search paths specified by the HINTS option. These should be paths computed by system
introspection, such as a hint provided by the location of another item already found. Hard-coded
guesses should be specified with the PATHS option.
4. Search the standard system environment variables. This can be skipped if
NO_SYSTEM_ENVIRONMENT_PATH is passed. Path entries ending in "/bin" or "/sbin" are automatically
converted to their parent directories.
PATH
5. Search project build trees recently configured in a CMake GUI. This can be skipped if
NO_CMAKE_BUILDS_PATH is passed. It is intended for the case when a user is building multiple
dependent projects one after another.
6. Search paths stored in the CMake user package registry. This can be skipped if
NO_CMAKE_PACKAGE_REGISTRY is passed. On Windows a <package> may appear under registry key
HKEY_CURRENT_USER\Software\Kitware\CMake\Packages\<package>
as a REG_SZ value, with arbitrary name, that specifies the directory containing the package
configuration file. On UNIX platforms a <package> may appear under the directory
~/.cmake/packages/<package>
as a file, with arbitrary name, whose content specifies the directory containing the package
configuration file. See the export(PACKAGE) command to create user package registry entries for
project build trees.
7. Search cmake variables defined in the Platform files for the current system. This can be
skipped if NO_CMAKE_SYSTEM_PATH is passed.
CMAKE_SYSTEM_PREFIX_PATH
CMAKE_SYSTEM_FRAMEWORK_PATH
CMAKE_SYSTEM_APPBUNDLE_PATH
8. Search paths stored in the CMake system package registry. This can be skipped if
NO_CMAKE_SYSTEM_PACKAGE_REGISTRY is passed. On Windows a <package> may appear under registry key
HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<package>
as a REG_SZ value, with arbitrary name, that specifies the directory containing the package
configuration file. There is no system package registry on non-Windows platforms.
9. Search paths specified by the PATHS option. These are typically hard-coded guesses.
On Darwin or systems supporting OS X Frameworks, the cmake variable CMAKE_FIND_FRAMEWORK 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.
On Darwin or systems supporting OS X Application Bundles, the cmake variable CMAKE_FIND_APPBUNDLE
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.
The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more directories to be prepended to all
other search directories. This effectively "re-roots" the entire search under given locations. By
default it is empty. It is especially useful when cross-compiling to point to the root directory
of the target environment and CMake will search there too. By default at first the directories
listed in CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be searched. The default
behavior can be adjusted by setting CMAKE_FIND_ROOT_PATH_MODE_PACKAGE. This behavior can be
manually overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH the search order will
be as described above. If NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
used. If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted directories will be searched.
The default search order is designed to be most-specific to least-specific for common use cases.
Projects may override the order by simply calling the command multiple times and using the NO_*
options:
find_package(<package> PATHS paths... NO_DEFAULT_PATH)
find_package(<package>)
Once one of the calls succeeds the result variable will be set and stored in the cache so that no
call will search again.
Every non-REQUIRED find_package() call can be disabled by setting the variable
CMAKE_DISABLE_FIND_PACKAGE_<package> to TRUE. See the documentation for the
CMAKE_DISABLE_FIND_PACKAGE_<package> variable for more information.
When loading a find module or package configuration file find_package defines variables to provide
information about the call arguments (and restores their original state before returning):
<package>_FIND_REQUIRED = true if REQUIRED option was given
<package>_FIND_QUIETLY = true if QUIET option was given
<package>_FIND_VERSION = full requested version string
<package>_FIND_VERSION_MAJOR = major version if requested, else 0
<package>_FIND_VERSION_MINOR = minor version if requested, else 0
<package>_FIND_VERSION_PATCH = patch version if requested, else 0
<package>_FIND_VERSION_TWEAK = tweak version if requested, else 0
<package>_FIND_VERSION_COUNT = number of version components, 0 to 4
<package>_FIND_VERSION_EXACT = true if EXACT option was given
<package>_FIND_COMPONENTS = list of requested components
<package>_FIND_REQUIRED_<c> = true if component <c> is required
false if component <c> is optional
In Module mode the loaded find module is responsible to honor the request detailed by these
variables; see the find module for details. In Config mode find_package handles REQUIRED, QUIET,
and version options automatically but leaves it to the package configuration file to handle
components in a way that makes sense for the package. The package configuration file may set
<package>_FOUND to false to tell find_package that component requirements are not satisfied.
See the cmake_policy() command documentation for discussion of the NO_POLICY_SCOPE option.
find_path
Find the directory containing a file.
find_path(<VAR> name1 [path1 path2 ...])
This is the short-hand signature for the command that is sufficient in many cases. It is the same
as find_path(<VAR> name1 [PATHS path1 path2 ...])
find_path(
<VAR>
name | NAMES name1 [name2 ...]
[HINTS path1 [path2 ... ENV var]]
[PATHS path1 [path2 ... ENV var]]
[PATH_SUFFIXES suffix1 [suffix2 ...]]
[DOC "cache documentation string"]
[NO_DEFAULT_PATH]
[NO_CMAKE_ENVIRONMENT_PATH]
[NO_CMAKE_PATH]
[NO_SYSTEM_ENVIRONMENT_PATH]
[NO_CMAKE_SYSTEM_PATH]
[CMAKE_FIND_ROOT_PATH_BOTH |
ONLY_CMAKE_FIND_ROOT_PATH |
NO_CMAKE_FIND_ROOT_PATH]
)
This command is used to find a directory containing the named file. A cache entry named by <VAR>
is created to store the result of this command. If the file in a directory is found the result is
stored in the variable and the search will not be repeated unless the variable is cleared. If
nothing is found, the result will be <VAR>-NOTFOUND, and the search will be attempted again the
next time find_path is invoked with the same variable. The name of the file in a directory that
is searched for is specified by the names listed after the NAMES argument. Additional search
locations can be specified after the PATHS argument. If ENV var is found in the HINTS or PATHS
section the environment variable var will be read and converted from a system environment variable
to a cmake style list of paths. For example ENV PATH would be a way to list the system path
variable. The argument after DOC will be used for the documentation string in the cache.
PATH_SUFFIXES specifies additional subdirectories to check below each search path.
If NO_DEFAULT_PATH is specified, then no additional paths are added to the search. If
NO_DEFAULT_PATH is not specified, the search process is as follows:
1. Search paths specified in cmake-specific cache variables. These are intended to be used on the
command line with a -DVAR=value. This can be skipped if NO_CMAKE_PATH is passed.
<prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
<prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_INCLUDE_PATH
CMAKE_FRAMEWORK_PATH
2. Search paths specified in cmake-specific environment variables. These are intended to be set
in the user's shell configuration. This can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
<prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
<prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_INCLUDE_PATH
CMAKE_FRAMEWORK_PATH
3. Search the paths specified by the HINTS option. These should be paths computed by system
introspection, such as a hint provided by the location of another item already found. Hard-coded
guesses should be specified with the PATHS option.
4. Search the standard system environment variables. This can be skipped if
NO_SYSTEM_ENVIRONMENT_PATH is an argument.
PATH
INCLUDE
5. Search cmake variables defined in the Platform files for the current system. This can be
skipped if NO_CMAKE_SYSTEM_PATH is passed.
<prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
<prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
CMAKE_SYSTEM_INCLUDE_PATH
CMAKE_SYSTEM_FRAMEWORK_PATH
6. Search the paths specified by the PATHS option or in the short-hand version of the command.
These are typically hard-coded guesses.
On Darwin or systems supporting OS X Frameworks, the cmake variable CMAKE_FIND_FRAMEWORK 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.
On Darwin or systems supporting OS X Application Bundles, the cmake variable CMAKE_FIND_APPBUNDLE
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.
The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more directories to be prepended to all
other search directories. This effectively "re-roots" the entire search under given locations. By
default it is empty. It is especially useful when cross-compiling to point to the root directory
of the target environment and CMake will search there too. By default at first the directories
listed in CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be searched. The default
behavior can be adjusted by setting CMAKE_FIND_ROOT_PATH_MODE_INCLUDE. This behavior can be
manually overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH the search order will
be as described above. If NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
used. If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted directories will be searched.
The default search order is designed to be most-specific to least-specific for common use cases.
Projects may override the order by simply calling the command multiple times and using the NO_*
options:
find_path(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
find_path(<VAR> NAMES name)
Once one of the calls succeeds the result variable will be set and stored in the cache so that no
call will search again.
When searching for frameworks, if the file is specified as A/b.h, then the framework search will
look for A.framework/Headers/b.h. If that is found the path will be set to the path to the
framework. CMake will convert this to the correct -F option to include the file.
find_program
Find an executable program.
find_program(<VAR> name1 [path1 path2 ...])
This is the short-hand signature for the command that is sufficient in many cases. It is the same
as find_program(<VAR> name1 [PATHS path1 path2 ...])
find_program(
<VAR>
name | NAMES name1 [name2 ...]
[HINTS path1 [path2 ... ENV var]]
[PATHS path1 [path2 ... ENV var]]
[PATH_SUFFIXES suffix1 [suffix2 ...]]
[DOC "cache documentation string"]
[NO_DEFAULT_PATH]
[NO_CMAKE_ENVIRONMENT_PATH]
[NO_CMAKE_PATH]
[NO_SYSTEM_ENVIRONMENT_PATH]
[NO_CMAKE_SYSTEM_PATH]
[CMAKE_FIND_ROOT_PATH_BOTH |
ONLY_CMAKE_FIND_ROOT_PATH |
NO_CMAKE_FIND_ROOT_PATH]
)
This command is used to find a program. A cache entry named by <VAR> is created to store the
result of this command. If the program is found the result is stored in the variable and the
search will not be repeated unless the variable is cleared. If nothing is found, the result will
be <VAR>-NOTFOUND, and the search will be attempted again the next time find_program is invoked
with the same variable. The name of the program that is searched for is specified by the names
listed after the NAMES argument. Additional search locations can be specified after the PATHS
argument. If ENV var is found in the HINTS or PATHS section the environment variable var will be
read and converted from a system environment variable to a cmake style list of paths. For example
ENV PATH would be a way to list the system path variable. The argument after DOC will be used for
the documentation string in the cache. PATH_SUFFIXES specifies additional subdirectories to check
below each search path.
If NO_DEFAULT_PATH is specified, then no additional paths are added to the search. If
NO_DEFAULT_PATH is not specified, the search process is as follows:
1. Search paths specified in cmake-specific cache variables. These are intended to be used on the
command line with a -DVAR=value. This can be skipped if NO_CMAKE_PATH is passed.
<prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_PROGRAM_PATH
CMAKE_APPBUNDLE_PATH
2. Search paths specified in cmake-specific environment variables. These are intended to be set
in the user's shell configuration. This can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
<prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
CMAKE_PROGRAM_PATH
CMAKE_APPBUNDLE_PATH
3. Search the paths specified by the HINTS option. These should be paths computed by system
introspection, such as a hint provided by the location of another item already found. Hard-coded
guesses should be specified with the PATHS option.
4. Search the standard system environment variables. This can be skipped if
NO_SYSTEM_ENVIRONMENT_PATH is an argument.
PATH
5. Search cmake variables defined in the Platform files for the current system. This can be
skipped if NO_CMAKE_SYSTEM_PATH is passed.
<prefix>/[s]bin for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
CMAKE_SYSTEM_PROGRAM_PATH
CMAKE_SYSTEM_APPBUNDLE_PATH
6. Search the paths specified by the PATHS option or in the short-hand version of the command.
These are typically hard-coded guesses.
On Darwin or systems supporting OS X Frameworks, the cmake variable CMAKE_FIND_FRAMEWORK 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.
On Darwin or systems supporting OS X Application Bundles, the cmake variable CMAKE_FIND_APPBUNDLE
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.
The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more directories to be prepended to all
other search directories. This effectively "re-roots" the entire search under given locations. By
default it is empty. It is especially useful when cross-compiling to point to the root directory
of the target environment and CMake will search there too. By default at first the directories
listed in CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be searched. The default
behavior can be adjusted by setting CMAKE_FIND_ROOT_PATH_MODE_PROGRAM. This behavior can be
manually overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH the search order will
be as described above. If NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
used. If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted directories will be searched.
The default search order is designed to be most-specific to least-specific for common use cases.
Projects may override the order by simply calling the command multiple times and using the NO_*
options:
find_program(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
find_program(<VAR> NAMES name)
Once one of the calls succeeds the result variable will be set and stored in the cache so that no
call will search again.
foreach
Evaluate a group of commands for each value in a list.
foreach(loop_var arg1 arg2 ...)
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
endforeach(loop_var)
All commands between foreach and the matching endforeach are recorded without being invoked. Once
the endforeach is evaluated, the recorded list of commands is invoked once for each argument
listed in the original foreach command. Before each iteration of the loop "${loop_var}" will be
set as a variable with the current value in the list.
foreach(loop_var RANGE total)
foreach(loop_var RANGE start stop [step])
Foreach can also iterate over a generated range of numbers. There are three types of this
iteration:
* When specifying single number, the range will have elements 0 to "total".
* When specifying two numbers, the range will have elements from the first number to the second
number.
* The third optional number is the increment used to iterate from the first number to the second
number.
foreach(loop_var IN [LISTS [list1 [...]]]
[ITEMS [item1 [...]]])
Iterates over a precise list of items. The LISTS option names list-valued variables to be
traversed, including empty elements (an empty string is a zero-length list). The ITEMS option
ends argument parsing and includes all arguments following it in the iteration.
function
Start recording a function for later invocation as a command.
function(<name> [arg1 [arg2 [arg3 ...]]])
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
endfunction(<name>)
Define a function named <name> that takes arguments named arg1 arg2 arg3 (...). Commands listed
after function, but before the matching endfunction, are not invoked until the function is
invoked. When it is invoked, the commands recorded in the function are first modified by
replacing formal parameters (${arg1}) with the arguments passed, and then invoked as normal
commands. In addition to referencing the formal parameters you can reference the variable ARGC
which will be set to the number of arguments passed into the function as well as ARGV0 ARGV1 ARGV2
... which will have the actual values of the arguments passed in. This facilitates creating
functions with optional arguments. Additionally ARGV holds the list of all arguments given to the
function and ARGN holds the list of arguments past the last expected argument.
A function opens a new scope: see set(var PARENT_SCOPE) for details.
See the cmake_policy() command documentation for the behavior of policies inside functions.
get_cmake_property
Get a property of the CMake instance.
get_cmake_property(VAR property)
Get a property from the CMake instance. The value of the property is stored in the variable VAR.
If the property is not found, VAR will be set to "NOTFOUND". Some supported properties include:
VARIABLES, CACHE_VARIABLES, COMMANDS, MACROS, and COMPONENTS.
See also the more general get_property() command.
get_directory_property
Get a property of DIRECTORY scope.
get_directory_property(<variable> [DIRECTORY <dir>] <prop-name>)
Store a property of directory scope in the named variable. If the property is not defined the
empty-string is returned. The DIRECTORY argument specifies another directory from which to
retrieve the property value. The specified directory must have already been traversed by CMake.
get_directory_property(<variable> [DIRECTORY <dir>]
DEFINITION <var-name>)
Get a variable definition from a directory. This form is useful to get a variable definition from
another directory.
See also the more general get_property() command.
get_filename_component
Get a specific component of a full filename.
get_filename_component(<VAR> <FileName> <COMP> [CACHE])
Set <VAR> to a component of <FileName>, where <COMP> is one of:
DIRECTORY = Directory without file name
NAME = File name without directory
EXT = File name longest extension (.b.c from d/a.b.c)
NAME_WE = File name without directory or longest extension
ABSOLUTE = Full path to file
REALPATH = Full path to existing file with symlinks resolved
PATH = Legacy alias for DIRECTORY (use for CMake <= 2.8.11)
Paths are returned with forward slashes and have no trailing slahes. The longest file extension is
always considered. If the optional CACHE argument is specified, the result variable is added to
the cache.
get_filename_component(<VAR> FileName
PROGRAM [PROGRAM_ARGS <ARG_VAR>]
[CACHE])
The program in FileName will be found in the system search path or left as a full path. If
PROGRAM_ARGS is present with PROGRAM, then any command-line arguments present in the FileName
string are split from the program name and stored in <ARG_VAR>. This is used to separate a
program name from its arguments in a command line string.
get_property
Get a property.
get_property(<variable>
<GLOBAL |
DIRECTORY [dir] |
TARGET <target> |
SOURCE <source> |
TEST <test> |
CACHE <entry> |
VARIABLE>
PROPERTY <name>
[SET | DEFINED | BRIEF_DOCS | FULL_DOCS])
Get one property from one object in a scope. The first argument specifies the variable in which
to store the result. The second argument determines the scope from which to get the property. It
must be one of the following:
GLOBAL scope is unique and does not accept a name.
DIRECTORY scope defaults to the current directory but another directory (already processed by
CMake) may be named by full or relative path.
TARGET scope must name one existing target.
SOURCE scope must name one source file.
TEST scope must name one existing test.
CACHE scope must name one cache entry.
VARIABLE scope is unique and does not accept a name.
The required PROPERTY option is immediately followed by the name of the property to get. If the
property is not set an empty value is returned. If the SET option is given the variable is set to
a boolean value indicating whether the property has been set. If the DEFINED option is given the
variable is set to a boolean value indicating whether the property has been defined such as with
define_property. If BRIEF_DOCS or FULL_DOCS is given then the variable is set to a string
containing documentation for the requested property. If documentation is requested for a property
that has not been defined NOTFOUND is returned.
if Conditionally execute a group of commands.
if(expression)
# then section.
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
elseif(expression2)
# elseif section.
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
else(expression)
# else section.
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
endif(expression)
Evaluates the given expression. If the result is true, the commands in the THEN section are
invoked. Otherwise, the commands in the else section are invoked. The elseif and else sections
are optional. You may have multiple elseif clauses. Note that the expression in the else and endif
clause is optional. Long expressions can be used and there is a traditional order of precedence.
Parenthetical expressions are evaluated first followed by unary operators such as EXISTS, COMMAND,
and DEFINED. Then any EQUAL, LESS, GREATER, STRLESS, STRGREATER, STREQUAL, MATCHES will be
evaluated. Then NOT operators and finally AND, OR operators will be evaluated. Possible
expressions are:
if(<constant>)
True if the constant is 1, ON, YES, TRUE, Y, or a non-zero number. False if the constant is 0,
OFF, NO, FALSE, N, IGNORE, NOTFOUND, '', or ends in the suffix '-NOTFOUND'. Named boolean
constants are case-insensitive. If the argument is not one of these constants, it is treated as a
variable:
if(<variable>)
True if the variable is defined to a value that is not a false constant. False otherwise. (Note
macro arguments are not variables.)
if(NOT <expression>)
True if the expression is not true.
if(<expr1> AND <expr2>)
True if both expressions would be considered true individually.
if(<expr1> OR <expr2>)
True if either expression would be considered true individually.
if(COMMAND command-name)
True if the given name is a command, macro or function that can be invoked.
if(POLICY policy-id)
True if the given name is an existing policy (of the form CMP<NNNN>).
if(TARGET target-name)
True if the given name is an existing target, built or imported.
if(EXISTS file-name)
if(EXISTS directory-name)
True if the named file or directory exists. Behavior is well-defined only for full paths.
if(file1 IS_NEWER_THAN file2)
True if file1 is newer than file2 or if one of the two files doesn't exist. Behavior is
well-defined only for full paths. If the file time stamps are exactly the same, an IS_NEWER_THAN
comparison returns true, so that any dependent build operations will occur in the event of a tie.
This includes the case of passing the same file name for both file1 and file2.
if(IS_DIRECTORY directory-name)
True if the given name is a directory. Behavior is well-defined only for full paths.
if(IS_SYMLINK file-name)
True if the given name is a symbolic link. Behavior is well-defined only for full paths.
if(IS_ABSOLUTE path)
True if the given path is an absolute path.
if(<variable|string> MATCHES regex)
True if the given string or variable's value matches the given regular expression.
if(<variable|string> LESS <variable|string>)
if(<variable|string> GREATER <variable|string>)
if(<variable|string> EQUAL <variable|string>)
True if the given string or variable's value is a valid number and the inequality or equality is
true.
if(<variable|string> STRLESS <variable|string>)
if(<variable|string> STRGREATER <variable|string>)
if(<variable|string> STREQUAL <variable|string>)
True if the given string or variable's value is lexicographically less (or greater, or equal) than
the string or variable on the right.
if(<variable|string> VERSION_LESS <variable|string>)
if(<variable|string> VERSION_EQUAL <variable|string>)
if(<variable|string> VERSION_GREATER <variable|string>)
Component-wise integer version number comparison (version format is
major[.minor[.patch[.tweak]]]).
if(DEFINED <variable>)
True if the given variable is defined. It does not matter if the variable is true or false just if
it has been set.
if((expression) AND (expression OR (expression)))
The expressions inside the parenthesis are evaluated first and then the remaining expression is
evaluated as in the previous examples. Where there are nested parenthesis the innermost are
evaluated as part of evaluating the expression that contains them.
The if command was written very early in CMake's history, predating the ${} variable evaluation
syntax, and for convenience evaluates variables named by its arguments as shown in the above
signatures. Note that normal variable evaluation with ${} applies before the if command even
receives the arguments. Therefore code like
set(var1 OFF)
set(var2 "var1")
if(${var2})
appears to the if command as
if(var1)
and is evaluated according to the if(<variable>) case documented above. The result is OFF which
is false. However, if we remove the ${} from the example then the command sees
if(var2)
which is true because var2 is defined to "var1" which is not a false constant.
Automatic evaluation applies in the other cases whenever the above-documented signature accepts
<variable|string>:
1) The left hand argument to MATCHES is first checked to see if it is a defined variable, if so
the variable's value is used, otherwise the original value is used.
2) If the left hand argument to MATCHES is missing it returns false without error
3) Both left and right hand arguments to LESS GREATER EQUAL are independently tested to see if
they are defined variables, if so their defined values are used otherwise the original value is
used.
4) Both left and right hand arguments to STRLESS STREQUAL STRGREATER are independently tested to
see if they are defined variables, if so their defined values are used otherwise the original
value is used.
5) Both left and right hand argumemnts to VERSION_LESS VERSION_EQUAL VERSION_GREATER are
independently tested to see if they are defined variables, if so their defined values are used
otherwise the original value is used.
6) The right hand argument to NOT is tested to see if it is a boolean constant, if so the value is
used, otherwise it is assumed to be a variable and it is dereferenced.
7) The left and right hand arguments to AND OR are independently tested to see if they are boolean
constants, if so they are used as such, otherwise they are assumed to be variables and are
dereferenced.
include
Load and run CMake code from a file or module.
include(<file|module> [OPTIONAL] [RESULT_VARIABLE <VAR>]
[NO_POLICY_SCOPE])
Load and run CMake code from the file given. Variable reads and writes access the scope of the
caller (dynamic scoping). If OPTIONAL is present, then no error is raised if the file does not
exist. If RESULT_VARIABLE is given the variable will be set to the full filename which has been
included or NOTFOUND if it failed.
If a module is specified instead of a file, the file with name <modulename>.cmake is searched
first in CMAKE_MODULE_PATH, then in the CMake module directory. There is one exception to this: if
the file which calls include() is located itself in the CMake module directory, then first the
CMake module directory is searched and CMAKE_MODULE_PATH afterwards. See also policy CMP0017.
See the cmake_policy() command documentation for discussion of the NO_POLICY_SCOPE option.
list List operations.
list(LENGTH <list> <output variable>)
list(GET <list> <element index> [<element index> ...]
<output variable>)
list(APPEND <list> <element> [<element> ...])
list(FIND <list> <value> <output variable>)
list(INSERT <list> <element_index> <element> [<element> ...])
list(REMOVE_ITEM <list> <value> [<value> ...])
list(REMOVE_AT <list> <index> [<index> ...])
list(REMOVE_DUPLICATES <list>)
list(REVERSE <list>)
list(SORT <list>)
LENGTH will return a given list's length.
GET will return list of elements specified by indices from the list.
APPEND will append elements to the list.
FIND will return the index of the element specified in the list or -1 if it wasn't found.
INSERT will insert elements to the list to the specified location.
REMOVE_AT and REMOVE_ITEM will remove items from the list. The difference is that REMOVE_ITEM will
remove the given items, while REMOVE_AT will remove the items at the given indices.
REMOVE_DUPLICATES will remove duplicated items in the list.
REVERSE reverses the contents of the list in-place.
SORT sorts the list in-place alphabetically.
The list subcommands APPEND, INSERT, REMOVE_AT, REMOVE_ITEM, REMOVE_DUPLICATES, REVERSE and SORT
may create new values for the list within the current CMake variable scope. Similar to the SET
command, the LIST command creates new variable values in the current scope, even if the list
itself is actually defined in a parent scope. To propagate the results of these operations
upwards, use SET with PARENT_SCOPE, SET with CACHE INTERNAL, or some other means of value
propagation.
NOTES: A list in cmake is a ; separated group of strings. To create a list the set command can be
used. For example, set(var a b c d e) creates a list with a;b;c;d;e, and set(var "a b c d e")
creates a string or a list with one item in it.
When specifying index values, if <element index> is 0 or greater, it is indexed from the beginning
of the list, with 0 representing the first list element. If <element index> is -1 or lesser, it is
indexed from the end of the list, with -1 representing the last list element. Be careful when
counting with negative indices: they do not start from 0. -0 is equivalent to 0, the first list
element.
macro Start recording a macro for later invocation as a command.
macro(<name> [arg1 [arg2 [arg3 ...]]])
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
endmacro(<name>)
Define a macro named <name> that takes arguments named arg1 arg2 arg3 (...). Commands listed
after macro, but before the matching endmacro, are not invoked until the macro is invoked. When
it is invoked, the commands recorded in the macro are first modified by replacing formal
parameters (${arg1}) with the arguments passed, and then invoked as normal commands. In addition
to referencing the formal parameters you can reference the values ${ARGC} which will be set to the
number of arguments passed into the function as well as ${ARGV0} ${ARGV1} ${ARGV2} ... which will
have the actual values of the arguments passed in. This facilitates creating macros with optional
arguments. Additionally ${ARGV} holds the list of all arguments given to the macro and ${ARGN}
holds the list of arguments past the last expected argument. Note that the parameters to a macro
and values such as ARGN are not variables in the usual CMake sense. They are string replacements
much like the C preprocessor would do with a macro. If you want true CMake variables and/or better
CMake scope control you should look at the function command.
See the cmake_policy() command documentation for the behavior of policies inside macros.
mark_as_advanced
Mark cmake cached variables as advanced.
mark_as_advanced([CLEAR|FORCE] VAR VAR2 VAR...)
Mark the named cached variables as advanced. An advanced variable will not be displayed in any of
the cmake GUIs unless the show advanced option is on. If CLEAR is the first argument advanced
variables are changed back to unadvanced. If FORCE is the first argument, then the variable is
made advanced. If neither FORCE nor CLEAR is specified, new values will be marked as advanced,
but if the variable already has an advanced/non-advanced state, it will not be changed.
It does nothing in script mode.
math Mathematical expressions.
math(EXPR <output variable> <math expression>)
EXPR evaluates mathematical expression and returns result in the output variable. Example
mathematical expression is '5 * ( 10 + 13 )'. Supported operators are + - * / % | & ^ ~ << >> * /
%. They have the same meaning as they do in C code.
message
Display a message to the user.
message([STATUS|WARNING|AUTHOR_WARNING|FATAL_ERROR|SEND_ERROR]
"message to display" ...)
The optional keyword determines the type of message:
(none) = Important information
STATUS = Incidental information
WARNING = CMake Warning, continue processing
AUTHOR_WARNING = CMake Warning (dev), continue processing
SEND_ERROR = CMake Error, continue processing,
but skip generation
FATAL_ERROR = CMake Error, stop processing and generation
The CMake command-line tool displays STATUS messages on stdout and all other message types on
stderr. The CMake GUI displays all messages in its log area. The interactive dialogs (ccmake and
CMakeSetup) show STATUS messages one at a time on a status line and other messages in interactive
pop-up boxes.
CMake Warning and Error message text displays using a simple markup language. Non-indented text
is formatted in line-wrapped paragraphs delimited by newlines. Indented text is considered
pre-formatted.
option Provides an option that the user can optionally select.
option(<option_variable> "help string describing option"
[initial value])
Provide an option for the user to select as ON or OFF. If no initial value is provided, OFF is
used.
If you have options that depend on the values of other options, see the module help for
CMakeDependentOption.
return Return from a file, directory or function.
return()
Returns from a file, directory or function. When this command is encountered in an included file
(via include() or find_package()), it causes processing of the current file to stop and control is
returned to the including file. If it is encountered in a file which is not included by another
file, e.g. a CMakeLists.txt, control is returned to the parent directory if there is one. If
return is called in a function, control is returned to the caller of the function. Note that a
macro is not a function and does not handle return like a function does.
separate_arguments
Parse space-separated arguments into a semicolon-separated list.
separate_arguments(<var> <UNIX|WINDOWS>_COMMAND "<args>")
Parses a unix- or windows-style command-line string "<args>" and stores a semicolon-separated list
of the arguments in <var>. The entire command line must be given in one "<args>" argument.
The UNIX_COMMAND mode separates arguments by unquoted whitespace. It recognizes both single-quote
and double-quote pairs. A backslash escapes the next literal character (\" is "); there are no
special escapes (\n is just n).
The WINDOWS_COMMAND mode parses a windows command-line using the same syntax the runtime library
uses to construct argv at startup. It separates arguments by whitespace that is not
double-quoted. Backslashes are literal unless they precede double-quotes. See the MSDN article
"Parsing C Command-Line Arguments" for details.
separate_arguments(VARIABLE)
Convert the value of VARIABLE to a semi-colon separated list. All spaces are replaced with ';'.
This helps with generating command lines.
set Set a CMake, cache or environment variable to a given value.
set(<variable> <value>
[[CACHE <type> <docstring> [FORCE]] | PARENT_SCOPE])
Within CMake sets <variable> to the value <value>. <value> is expanded before <variable> is set
to it. Normally, set will set a regular CMake variable. If CACHE is present, then the <variable>
is put in the cache instead, unless it is already in the cache. See section 'Variable types in
CMake' below for details of regular and cache variables and their interactions. If CACHE is used,
<type> and <docstring> are required. <type> is used by the CMake GUI to choose a widget with which
the user sets a value. The value for <type> may be one of
FILEPATH = File chooser dialog.
PATH = Directory chooser dialog.
STRING = Arbitrary string.
BOOL = Boolean ON/OFF checkbox.
INTERNAL = No GUI entry (used for persistent variables).
If <type> is INTERNAL, the cache variable is marked as internal, and will not be shown to the user
in tools like cmake-gui. This is intended for values that should be persisted in the cache, but
which users should not normally change. INTERNAL implies FORCE.
Normally, set(...CACHE...) creates cache variables, but does not modify them. If FORCE is
specified, the value of the cache variable is set, even if the variable is already in the cache.
This should normally be avoided, as it will remove any changes to the cache variable's value by
the user.
If PARENT_SCOPE is present, the variable will be set in the scope above the current scope. Each
new directory or function creates a new scope. This command will set the value of a variable into
the parent directory or calling function (whichever is applicable to the case at hand).
PARENT_SCOPE cannot be combined with CACHE.
If <value> is not specified then the variable is removed instead of set. See also: the unset()
command.
set(<variable> <value1> ... <valueN>)
In this case <variable> is set to a semicolon separated list of values.
<variable> can be an environment variable such as:
set( ENV{PATH} /home/martink )
in which case the environment variable will be set.
*** Variable types in CMake ***
In CMake there are two types of variables: normal variables and cache variables. Normal variables
are meant for the internal use of the script (just like variables in most programming languages);
they are not persisted across CMake runs. Cache variables (unless set with INTERNAL) are mostly
intended for configuration settings where the first CMake run determines a suitable default value,
which the user can then override, by editing the cache with tools such as ccmake or cmake-gui.
Cache variables are stored in the CMake cache file, and are persisted across CMake runs.
Both types can exist at the same time with the same name but different values. When ${FOO} is
evaluated, CMake first looks for a normal variable 'FOO' in scope and uses it if set. If and only
if no normal variable exists then it falls back to the cache variable 'FOO'.
Some examples:
The code 'set(FOO "x")' sets the normal variable 'FOO'. It does not touch the cache, but it will
hide any existing cache value 'FOO'.
The code 'set(FOO "x" CACHE ...)' checks for 'FOO' in the cache, ignoring any normal variable of
the same name. If 'FOO' is in the cache then nothing happens to either the normal variable or the
cache variable. If 'FOO' is not in the cache, then it is added to the cache.
Finally, whenever a cache variable is added or modified by a command, CMake also *removes* the
normal variable of the same name from the current scope so that an immediately following
evaluation of it will expose the newly cached value.
Normally projects should avoid using normal and cache variables of the same name, as this
interaction can be hard to follow. However, in some situations it can be useful. One example (used
by some projects):
A project has a subproject in its source tree. The child project has its own CMakeLists.txt, which
is included from the parent CMakeLists.txt using add_subdirectory(). Now, if the parent and the
child project provide the same option (for example a compiler option), the parent gets the first
chance to add a user-editable option to the cache. Normally, the child would then use the same
value that the parent uses. However, it may be necessary to hard-code the value for the child
project's option while still allowing the user to edit the value used by the parent project. The
parent project can achieve this simply by setting a normal variable with the same name as the
option in a scope sufficient to hide the option's cache variable from the child completely. The
parent has already set the cache variable, so the child's set(...CACHE...) will do nothing, and
evaluating the option variable will use the value from the normal variable, which hides the cache
variable.
set_directory_properties
Set a property of the directory.
set_directory_properties(PROPERTIES prop1 value1 prop2 value2)
Set a property for the current directory and subdirectories. If the property is not found, CMake
will report an error. The properties include: INCLUDE_DIRECTORIES, LINK_DIRECTORIES,
INCLUDE_REGULAR_EXPRESSION, and ADDITIONAL_MAKE_CLEAN_FILES. ADDITIONAL_MAKE_CLEAN_FILES is a list
of files that will be cleaned as a part of "make clean" stage.
set_property
Set a named property in a given scope.
set_property(<GLOBAL |
DIRECTORY [dir] |
TARGET [target1 [target2 ...]] |
SOURCE [src1 [src2 ...]] |
TEST [test1 [test2 ...]] |
CACHE [entry1 [entry2 ...]]>
[APPEND] [APPEND_STRING]
PROPERTY <name> [value1 [value2 ...]])
Set one property on zero or more objects of a scope. The first argument determines the scope in
which the property is set. It must be one of the following:
GLOBAL scope is unique and does not accept a name.
DIRECTORY scope defaults to the current directory but another directory (already processed by
CMake) may be named by full or relative path.
TARGET scope may name zero or more existing targets.
SOURCE scope may name zero or more source files. Note that source file properties are visible
only to targets added in the same directory (CMakeLists.txt).
TEST scope may name zero or more existing tests.
CACHE scope must name zero or more cache existing entries.
The required PROPERTY option is immediately followed by the name of the property to set.
Remaining arguments are used to compose the property value in the form of a semicolon-separated
list. If the APPEND option is given the list is appended to any existing property value.If the
APPEND_STRING option is given the string is append to any existing property value as string, i.e.
it results in a longer string and not a list of strings.
site_name
Set the given variable to the name of the computer.
site_name(variable)
string String operations.
string(REGEX MATCH <regular_expression>
<output variable> <input> [<input>...])
string(REGEX MATCHALL <regular_expression>
<output variable> <input> [<input>...])
string(REGEX REPLACE <regular_expression>
<replace_expression> <output variable>
<input> [<input>...])
string(REPLACE <match_string>
<replace_string> <output variable>
<input> [<input>...])
string(<MD5|SHA1|SHA224|SHA256|SHA384|SHA512>

string(COMPARE EQUAL <string1> <string2> <output variable>)
string(COMPARE NOTEQUAL <string1> <string2> <output variable>)
string(COMPARE LESS <string1> <string2> <output variable>)
string(COMPARE GREATER <string1> <string2> <output variable>)
string(ASCII <number> [<number> ...] <output variable>)
string(CONFIGURE <string1> <output variable>
[@ONLY] [ESCAPE_QUOTES])
string(TOUPPER <string1> <output variable>)
string(TOLOWER <string1> <output variable>)
string(LENGTH <string> <output variable>)
string(SUBSTRING <string> <begin> <length> <output variable>)
string(STRIP <string> <output variable>)
string(RANDOM [LENGTH <length>] [ALPHABET <alphabet>]
[RANDOM_SEED <seed>] <output variable>)
string(FIND <string> <substring> <output variable> [REVERSE])
string(TIMESTAMP <output variable> [<format string>] [UTC])
string(MAKE_C_IDENTIFIER <input string> <output variable>)
REGEX MATCH will match the regular expression once and store the match in the output variable.
REGEX MATCHALL will match the regular expression as many times as possible and store the matches
in the output variable as a list.
REGEX REPLACE will match the regular expression as many times as possible and substitute the
replacement expression for the match in the output. The replace expression may refer to
paren-delimited subexpressions of the match using \1, \2, ..., \9. Note that two backslashes
(\\1) are required in CMake code to get a backslash through argument parsing.
REPLACE will replace all occurrences of match_string in the input with replace_string and store
the result in the output.
MD5, SHA1, SHA224, SHA256, SHA384, and SHA512 will compute a cryptographic hash of the input
string.
COMPARE EQUAL/NOTEQUAL/LESS/GREATER will compare the strings and store true or false in the output
variable.
ASCII will convert all numbers into corresponding ASCII characters.
CONFIGURE will transform a string like CONFIGURE_FILE transforms a file.
TOUPPER/TOLOWER will convert string to upper/lower characters.
LENGTH will return a given string's length.
SUBSTRING will return a substring of a given string. If length is -1 the remainder of the string
starting at begin will be returned.
STRIP will return a substring of a given string with leading and trailing spaces removed.
RANDOM will return a random string of given length consisting of characters from the given
alphabet. Default length is 5 characters and default alphabet is all numbers and upper and lower
case letters. If an integer RANDOM_SEED is given, its value will be used to seed the random
number generator.
FIND will return the position where the given substring was found in the supplied string. If the
REVERSE flag was used, the command will search for the position of the last occurrence of the
specified substring.
The following characters have special meaning in regular expressions:
^ Matches at beginning of input
$ Matches at end of input
. Matches any single character
[ ] Matches any character(s) inside the brackets
[^ ] Matches any character(s) not inside the brackets
- Inside brackets, specifies an inclusive range between
characters on either side e.g. [a-f] is [abcdef]
To match a literal - using brackets, make it the first
or the last character e.g. [+*/-] matches basic
mathematical operators.
* Matches preceding pattern zero or more times
+ Matches preceding pattern one or more times
? Matches preceding pattern zero or once only
| Matches a pattern on either side of the |
() Saves a matched subexpression, which can be referenced
in the REGEX REPLACE operation. Additionally it is saved
by all regular expression-related commands, including
e.g. if( MATCHES ), in the variables CMAKE_MATCH_(0..9).
*, + and ? have higher precedence than concatenation. | has lower precedence than concatenation.
This means that the regular expression "^ab+d$" matches "abbd" but not "ababd", and the regular
expression "^(ab|cd)$" matches "ab" but not "abd".
TIMESTAMP will write a string representation of the current date and/or time to the output
variable.
Should the command be unable to obtain a timestamp the output variable will be set to the empty
string "".
The optional UTC flag requests the current date/time representation to be in Coordinated Universal
Time (UTC) rather than local time.
The optional <format string> may contain the following format specifiers:
%d The day of the current month (01-31).
%H The hour on a 24-hour clock (00-23).
%I The hour on a 12-hour clock (01-12).
%j The day of the current year (001-366).
%m The month of the current year (01-12).
%M The minute of the current hour (00-59).
%S The second of the current minute.
60 represents a leap second. (00-60)
%U The week number of the current year (00-53).
%w The day of the current week. 0 is Sunday. (0-6)
%y The last two digits of the current year (00-99)
%Y The current year.
Unknown format specifiers will be ignored and copied to the output as-is.
If no explicit <format string> is given it will default to:
%Y-%m-%dT%H:%M:%S for local time.
%Y-%m-%dT%H:%M:%SZ for UTC.
MAKE_C_IDENTIFIER will write a string which can be used as an identifier in C.
unset Unset a variable, cache variable, or environment variable.
unset(<variable> [CACHE])
Removes the specified variable causing it to become undefined. If CACHE is present then the
variable is removed from the cache instead of the current scope.
<variable> can be an environment variable such as:
unset(ENV{LD_LIBRARY_PATH})
in which case the variable will be removed from the current environment.
variable_watch
Watch the CMake variable for change.
variable_watch(<variable name> [<command to execute>])
If the specified variable changes, the message will be printed about the variable being changed.
If the command is specified, the command will be executed. The command will receive the following
arguments: COMMAND(<variable> <access> <value> <current list file> <stack>)
while Evaluate a group of commands while a condition is true
while(condition)
COMMAND1(ARGS ...)
COMMAND2(ARGS ...)
...
endwhile(condition)
All commands between while and the matching endwhile are recorded without being invoked. Once the
endwhile is evaluated, the recorded list of commands is invoked as long as the condition is true.
The condition is evaluated using the same logic as the if command.
COMPATIBILITY COMMANDS
CMake Compatibility Listfile Commands - Obsolete commands supported by CMake for compatibility.
This is the documentation for now obsolete listfile commands from previous CMake versions, which are
still supported for compatibility reasons. You should instead use the newer, faster and shinier new
commands. ;-)
MODULES
PROPERTIES OF GLOBAL SCOPE
ALLOW_DUPLICATE_CUSTOM_TARGETS
Allow duplicate custom targets to be created.
Normally CMake requires that all targets built in a project have globally unique logical names
(see policy CMP0002). This is necessary to generate meaningful project file names in Xcode and VS
IDE generators. It also allows the target names to be referenced unambiguously.
Makefile generators are capable of supporting duplicate custom target names. For projects that
care only about Makefile generators and do not wish to support Xcode or VS IDE generators, one may
set this property to true to allow duplicate custom targets. The property allows multiple
add_custom_target command calls in different directories to specify the same target name.
However, setting this property will cause non-Makefile generators to produce an error and refuse
to generate the project.
AUTOMOC_TARGETS_FOLDER
Name of FOLDER for *_automoc targets that are added automatically by CMake for targets for which
AUTOMOC is enabled.
If not set, CMake uses the FOLDER property of the parent target as a default value for this
property. See also the documentation for the FOLDER target property and the AUTOMOC target
property.
DEBUG_CONFIGURATIONS
Specify which configurations are for debugging.
The value must be a semi-colon separated list of configuration names. Currently this property is
used only by the target_link_libraries command (see its documentation for details). Additional
uses may be defined in the future.
This property must be set at the top level of the project and before the first
target_link_libraries command invocation. If any entry in the list does not match a valid
configuration for the project the behavior is undefined.
DISABLED_FEATURES
List of features which are disabled during the CMake run.
List of features which are disabled during the CMake run. By default it contains the names of all
packages which were not found. This is determined using the <NAME>_FOUND variables. Packages which
are searched QUIET are not listed. A project can add its own features to this list. This property
is used by the macros in FeatureSummary.cmake.
ENABLED_FEATURES
List of features which are enabled during the CMake run.
List of features which are enabled during the CMake run. By default it contains the names of all
packages which were found. This is determined using the <NAME>_FOUND variables. Packages which are
searched QUIET are not listed. A project can add its own features to this list. This property is
used by the macros in FeatureSummary.cmake.
ENABLED_LANGUAGES
Read-only property that contains the list of currently enabled languages
Set to list of currently enabled languages.
FIND_LIBRARY_USE_LIB64_PATHS
Whether FIND_LIBRARY should automatically search lib64 directories.
FIND_LIBRARY_USE_LIB64_PATHS is a boolean specifying whether the FIND_LIBRARY command should
automatically search the lib64 variant of directories called lib in the search path when building
64-bit binaries.
FIND_LIBRARY_USE_OPENBSD_VERSIONING
Whether FIND_LIBRARY should find OpenBSD-style shared libraries.
This property is a boolean specifying whether the FIND_LIBRARY command should find shared
libraries with OpenBSD-style versioned extension: ".so.<major>.<minor>". The property is set to
true on OpenBSD and false on other platforms.
GLOBAL_DEPENDS_DEBUG_MODE
Enable global target dependency graph debug mode.
CMake automatically analyzes the global inter-target dependency graph at the beginning of native
build system generation. This property causes it to display details of its analysis to stderr.
GLOBAL_DEPENDS_NO_CYCLES
Disallow global target dependency graph cycles.
CMake automatically analyzes the global inter-target dependency graph at the beginning of native
build system generation. It reports an error if the dependency graph contains a cycle that does
not consist of all STATIC library targets. This property tells CMake to disallow all cycles
completely, even among static libraries.
IN_TRY_COMPILE
Read-only property that is true during a try-compile configuration.
True when building a project inside a TRY_COMPILE or TRY_RUN command.
PACKAGES_FOUND
List of packages which were found during the CMake run.
List of packages which were found during the CMake run. Whether a package has been found is
determined using the <NAME>_FOUND variables.
PACKAGES_NOT_FOUND
List of packages which were not found during the CMake run.
List of packages which were not found during the CMake run. Whether a package has been found is
determined using the <NAME>_FOUND variables.
PREDEFINED_TARGETS_FOLDER
Name of FOLDER for targets that are added automatically by CMake.
If not set, CMake uses "CMakePredefinedTargets" as a default value for this property. Targets such
as INSTALL, PACKAGE and RUN_TESTS will be organized into this FOLDER. See also the documentation
for the FOLDER target property.
REPORT_UNDEFINED_PROPERTIES
If set, report any undefined properties to this file.
If this property is set to a filename then when CMake runs it will report any properties or
variables that were accessed but not defined into the filename specified in this property.
RULE_LAUNCH_COMPILE
Specify a launcher for compile rules.
Makefile generators prefix compiler commands with the given launcher command line. This is
intended to allow launchers to intercept build problems with high granularity. Non-Makefile
generators currently ignore this property.
RULE_LAUNCH_CUSTOM
Specify a launcher for custom rules.
Makefile generators prefix custom commands with the given launcher command line. This is intended
to allow launchers to intercept build problems with high granularity. Non-Makefile generators
currently ignore this property.
RULE_LAUNCH_LINK
Specify a launcher for link rules.
Makefile generators prefix link and archive commands with the given launcher command line. This
is intended to allow launchers to intercept build problems with high granularity. Non-Makefile
generators currently ignore this property.
RULE_MESSAGES
Specify whether to report a message for each make rule.
This property specifies whether Makefile generators should add a progress message describing what
each build rule does. If the property is not set the default is ON. Set the property to OFF to
disable granular messages and report only as each target completes. This is intended to allow
scripted builds to avoid the build time cost of detailed reports. If a CMAKE_RULE_MESSAGES cache
entry exists its value initializes the value of this property. Non-Makefile generators currently
ignore this property.
TARGET_ARCHIVES_MAY_BE_SHARED_LIBS
Set if shared libraries may be named like archives.
On AIX shared libraries may be named "lib<name>.a". This property is set to true on such
platforms.
TARGET_SUPPORTS_SHARED_LIBS
Does the target platform support shared libraries.
TARGET_SUPPORTS_SHARED_LIBS is a boolean specifying whether the target platform supports shared
libraries. Basically all current general general purpose OS do so, the exception are usually
embedded systems with no or special OSs.
USE_FOLDERS
Use the FOLDER target property to organize targets into folders.
If not set, CMake treats this property as OFF by default. CMake generators that are capable of
organizing into a hierarchy of folders use the values of the FOLDER target property to name those
folders. See also the documentation for the FOLDER target property.
__CMAKE_DELETE_CACHE_CHANGE_VARS_
Internal property
Used to detect compiler changes, Do not set.
PROPERTIES ON CACHE ENTRIES
ADVANCED
True if entry should be hidden by default in GUIs.
This is a boolean value indicating whether the entry is considered interesting only for advanced
configuration. The mark_as_advanced() command modifies this property.
HELPSTRING
Help associated with entry in GUIs.
This string summarizes the purpose of an entry to help users set it through a CMake GUI.
MODIFIED
Internal management property. Do not set or get.
This is an internal cache entry property managed by CMake to track interactive user modification
of entries. Ignore it.
STRINGS
Enumerate possible STRING entry values for GUI selection.
For cache entries with type STRING, this enumerates a set of values. CMake GUIs may use this to
provide a selection widget instead of a generic string entry field. This is for convenience only.
CMake does not enforce that the value matches one of those listed.
TYPE Widget type for entry in GUIs.
Cache entry values are always strings, but CMake GUIs present widgets to help users set values.
The GUIs use this property as a hint to determine the widget type. Valid TYPE values are:
BOOL = Boolean ON/OFF value.
PATH = Path to a directory.
FILEPATH = Path to a file.
STRING = Generic string value.
INTERNAL = Do not present in GUI at all.
STATIC = Value managed by CMake, do not change.
UNINITIALIZED = Type not yet specified.
Generally the TYPE of a cache entry should be set by the command which creates it (set, option,
find_library, etc.).
VALUE Value of a cache entry.
This property maps to the actual value of a cache entry. Setting this property always sets the
value without checking, so use with care.
PROPERTIES ON DIRECTORIES
ADDITIONAL_MAKE_CLEAN_FILES
Additional files to clean during the make clean stage.
A list of files that will be cleaned as a part of the "make clean" stage.
CACHE_VARIABLES
List of cache variables available in the current directory.
This read-only property specifies the list of CMake cache variables currently defined. It is
intended for debugging purposes.
CLEAN_NO_CUSTOM
Should the output of custom commands be left.
If this is true then the outputs of custom commands for this directory will not be removed during
the "make clean" stage.
COMPILE_DEFINITIONS
Preprocessor definitions for compiling a directory's sources.
The COMPILE_DEFINITIONS property may be set to a semicolon-separated list of preprocessor
definitions using the syntax VAR or VAR=value. Function-style definitions are not supported.
CMake will automatically escape the value correctly for the native build system (note that CMake
language syntax may require escapes to specify some values). This property may be set on a
per-configuration basis using the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an
upper-case name (ex. "COMPILE_DEFINITIONS_DEBUG"). This property will be initialized in each
directory by its value in the directory's parent.
CMake will automatically drop some definitions that are not supported by the native build tool.
The VS6 IDE does not support definition values with spaces (but NMake does).
Disclaimer: Most native build tools have poor support for escaping certain values. CMake has
work-arounds for many cases but some values may just not be possible to pass correctly. If a
value does not seem to be escaped correctly, do not attempt to work-around the problem by adding
escape sequences to the value. Your work-around may break in a future version of CMake that has
improved escape support. Instead consider defining the macro in a (configured) header file. Then
report the limitation. Known limitations include:
# - broken almost everywhere
; - broken in VS IDE 7.0 and Borland Makefiles
, - broken in VS IDE
% - broken in some cases in NMake
& | - broken in some cases on MinGW
^ < > \" - broken in most Make tools on Windows
CMake does not reject these values outright because they do work in some cases. Use with caution.
COMPILE_DEFINITIONS_<CONFIG>
Per-configuration preprocessor definitions in a directory.
This is the configuration-specific version of COMPILE_DEFINITIONS. This property will be
initialized in each directory by its value in the directory's parent.
COMPILE_OPTIONS
List of options to pass to the compiler.
This property specifies the list of directories given so far for this property. This property
exists on directories and targets.
The target property values are used by the generators to set the options for the compiler.
Contents of COMPILE_OPTIONS may use "generator expressions" with the syntax "$<...>". Generator
expressions are evaluated during build system generation to produce information specific to each
build configuration. Valid expressions are:
$<0:...> = empty string (ignores "...")
$<1:...> = content of "..."
$<CONFIG:cfg> = '1' if config is "cfg", else '0'
$<CONFIGURATION> = configuration name
$<BOOL:...> = '1' if the '...' is true, else '0'
$<STREQUAL:a,b> = '1' if a is STREQUAL b, else '0'
$<ANGLE-R> = A literal '>'. Used to compare strings which contain a '>' for example.
$<COMMA> = A literal ','. Used to compare strings which contain a ',' for example.
$<SEMICOLON> = A literal ';'. Used to prevent list expansion on an argument with ';'.
$<JOIN:list,...> = joins the list with the content of "..."
$<TARGET_NAME:...> = Marks ... as being the name of a target. This is required if exporting targets to multiple dependent export sets. The '...' must be a literal name of a target- it may not contain generator expressions.
$<INSTALL_INTERFACE:...> = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
$<BUILD_INTERFACE:...> = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
$<C_COMPILER_ID> = The CMake-id of the C compiler used.
$<C_COMPILER_ID:comp> = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
$<CXX_COMPILER_ID> = The CMake-id of the CXX compiler used.
$<CXX_COMPILER_ID:comp> = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
$<VERSION_GREATER:v1,v2> = '1' if v1 is a version greater than v2, else '0'.
$<VERSION_LESS:v1,v2> = '1' if v1 is a version less than v2, else '0'.
$<VERSION_EQUAL:v1,v2> = '1' if v1 is the same version as v2, else '0'.
$<C_COMPILER_VERSION> = The version of the C compiler used.
$<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
$<CXX_COMPILER_VERSION> = The version of the CXX compiler used.
$<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
$<TARGET_FILE:tgt> = main file (.exe, .so.1.2, .a)
$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
where "tgt" is the name of a target. Target file expressions produce a full path, but _DIR and
_NAME versions can produce the directory and file name components:
$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
$<TARGET_PROPERTY:tgt,prop> = The value of the property prop on the target tgt.
Note that tgt is not added as a dependency of the target this expression is evaluated on.
$<TARGET_POLICY:pol> = '1' if the policy was NEW when the 'head' target was created, else '0'. If the policy was not set, the warning message for the policy will be emitted. This generator expression only works for a subset of policies.
$<INSTALL_PREFIX> = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.
Boolean expressions:
$<AND:?[,?]...> = '1' if all '?' are '1', else '0'
$<OR:?[,?]...> = '0' if all '?' are '0', else '1'
$<NOT:?> = '0' if '?' is '1', else '1'
where '?' is always either '0' or '1'.
Expressions with an implicit 'this' target:
$<TARGET_PROPERTY:prop> = The value of the property prop on the target on which the generator expression is evaluated.
DEFINITIONS
For CMake 2.4 compatibility only. Use COMPILE_DEFINITIONS instead.
This read-only property specifies the list of flags given so far to the add_definitions command.
It is intended for debugging purposes. Use the COMPILE_DEFINITIONS instead.
EXCLUDE_FROM_ALL
Exclude the directory from the all target of its parent.
A property on a directory that indicates if its targets are excluded from the default build
target. If it is not, then with a Makefile for example typing make will cause the targets to be
built. The same concept applies to the default build of other generators.
IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
Specify #include line transforms for dependencies in a directory.
This property specifies rules to transform macro-like #include lines during implicit dependency
scanning of C and C++ source files. The list of rules must be semicolon-separated with each entry
of the form "A_MACRO(%)=value-with-%" (the % must be literal). During dependency scanning
occurrences of A_MACRO(...) on #include lines will be replaced by the value given with the macro
argument substituted for '%'. For example, the entry
MYDIR(%)=<mydir/%>
will convert lines of the form
#include MYDIR(myheader.h)
to
#include <mydir/myheader.h>
allowing the dependency to be followed.
This property applies to sources in all targets within a directory. The property value is
initialized in each directory by its value in the directory's parent.
INCLUDE_DIRECTORIES
List of preprocessor include file search directories.
This property specifies the list of directories given so far to the include_directories command.
This property exists on directories and targets. In addition to accepting values from the
include_directories command, values may be set directly on any directory or any target using the
set_property command. A target gets its initial value for this property from the value of the
directory property. A directory gets its initial value from its parent directory if it has one.
Both directory and target property values are adjusted by calls to the include_directories
command.
The target property values are used by the generators to set the include paths for the compiler.
See also the include_directories command.
INCLUDE_REGULAR_EXPRESSION
Include file scanning regular expression.
This read-only property specifies the regular expression used during dependency scanning to match
include files that should be followed. See the include_regular_expression command.
INTERPROCEDURAL_OPTIMIZATION
Enable interprocedural optimization for targets in a directory.
If set to true, enables interprocedural optimizations if they are known to be supported by the
compiler.
INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
Per-configuration interprocedural optimization for a directory.
This is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION. If set, this property
overrides the generic property for the named configuration.
LINK_DIRECTORIES
List of linker search directories.
This read-only property specifies the list of directories given so far to the link_directories
command. It is intended for debugging purposes.
LISTFILE_STACK
The current stack of listfiles being processed.
This property is mainly useful when trying to debug errors in your CMake scripts. It returns a
list of what list files are currently being processed, in order. So if one listfile does an
INCLUDE command then that is effectively pushing the included listfile onto the stack.
MACROS List of macro commands available in the current directory.
This read-only property specifies the list of CMake macros currently defined. It is intended for
debugging purposes. See the macro command.
PARENT_DIRECTORY
Source directory that added current subdirectory.
This read-only property specifies the source directory that added the current source directory as
a subdirectory of the build. In the top-level directory the value is the empty-string.
RULE_LAUNCH_COMPILE
Specify a launcher for compile rules.
See the global property of the same name for details. This overrides the global property for a
directory.
RULE_LAUNCH_CUSTOM
Specify a launcher for custom rules.
See the global property of the same name for details. This overrides the global property for a
directory.
RULE_LAUNCH_LINK
Specify a launcher for link rules.
See the global property of the same name for details. This overrides the global property for a
directory.
TEST_INCLUDE_FILE
A cmake file that will be included when ctest is run.
If you specify TEST_INCLUDE_FILE, that file will be included and processed when ctest is run on
the directory.
VARIABLES
List of variables defined in the current directory.
This read-only property specifies the list of CMake variables currently defined. It is intended
for debugging purposes.
VS_GLOBAL_SECTION_POST_<section>
Specify a postSolution global section in Visual Studio.
Setting a property like this generates an entry of the following form in the solution file:
GlobalSection(<section>) = postSolution
<contents based on property value>
EndGlobalSection
The property must be set to a semicolon-separated list of key=value pairs. Each such pair will be
transformed into an entry in the solution global section. Whitespace around key and value is
ignored. List elements which do not contain an equal sign are skipped.
This property only works for Visual Studio 7 and above; it is ignored on other generators. The
property only applies when set on a directory whose CMakeLists.txt contains a project() command.
Note that CMake generates postSolution sections ExtensibilityGlobals and ExtensibilityAddIns by
default. If you set the corresponding property, it will override the default section. For example,
setting VS_GLOBAL_SECTION_POST_ExtensibilityGlobals will override the default contents of the
ExtensibilityGlobals section, while keeping ExtensibilityAddIns on its default.
VS_GLOBAL_SECTION_PRE_<section>
Specify a preSolution global section in Visual Studio.
Setting a property like this generates an entry of the following form in the solution file:
GlobalSection(<section>) = preSolution
<contents based on property value>
EndGlobalSection
The property must be set to a semicolon-separated list of key=value pairs. Each such pair will be
transformed into an entry in the solution global section. Whitespace around key and value is
ignored. List elements which do not contain an equal sign are skipped.
This property only works for Visual Studio 7 and above; it is ignored on other generators. The
property only applies when set on a directory whose CMakeLists.txt contains a project() command.
PROPERTIES ON SOURCE FILES
ABSTRACT
Is this source file an abstract class.
A property on a source file that indicates if the source file represents a class that is abstract.
This only makes sense for languages that have a notion of an abstract class and it is only used by
some tools that wrap classes into other languages.
COMPILE_DEFINITIONS
Preprocessor definitions for compiling a source file.
The COMPILE_DEFINITIONS property may be set to a semicolon-separated list of preprocessor
definitions using the syntax VAR or VAR=value. Function-style definitions are not supported.
CMake will automatically escape the value correctly for the native build system (note that CMake
language syntax may require escapes to specify some values). This property may be set on a
per-configuration basis using the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an
upper-case name (ex. "COMPILE_DEFINITIONS_DEBUG").
CMake will automatically drop some definitions that are not supported by the native build tool.
The VS6 IDE does not support definition values with spaces (but NMake does). Xcode does not
support per-configuration definitions on source files.
Disclaimer: Most native build tools have poor support for escaping certain values. CMake has
work-arounds for many cases but some values may just not be possible to pass correctly. If a
value does not seem to be escaped correctly, do not attempt to work-around the problem by adding
escape sequences to the value. Your work-around may break in a future version of CMake that has
improved escape support. Instead consider defining the macro in a (configured) header file. Then
report the limitation. Known limitations include:
# - broken almost everywhere
; - broken in VS IDE 7.0 and Borland Makefiles
, - broken in VS IDE
% - broken in some cases in NMake
& | - broken in some cases on MinGW
^ < > \" - broken in most Make tools on Windows
CMake does not reject these values outright because they do work in some cases. Use with caution.
COMPILE_DEFINITIONS_<CONFIG>
Per-configuration preprocessor definitions on a source file.
This is the configuration-specific version of COMPILE_DEFINITIONS. Note that Xcode does not
support per-configuration source file flags so this property will be ignored by the Xcode
generator.
COMPILE_FLAGS
Additional flags to be added when compiling this source file.
These flags will be added to the list of compile flags when this source file builds. Use
COMPILE_DEFINITIONS to pass additional preprocessor definitions.
EXTERNAL_OBJECT
If set to true then this is an object file.
If this property is set to true then the source file is really an object file and should not be
compiled. It will still be linked into the target though.
Fortran_FORMAT
Set to FIXED or FREE to indicate the Fortran source layout.
This property tells CMake whether a given Fortran source file uses fixed-format or free-format.
CMake will pass the corresponding format flag to the compiler. Consider using the target-wide
Fortran_FORMAT property if all source files in a target share the same format.
GENERATED
Is this source file generated as part of the build process.
If a source file is generated by the build process CMake will handle it differently in terms of
dependency checking etc. Otherwise having a non-existent source file could create problems.
HEADER_FILE_ONLY
Is this source file only a header file.
A property on a source file that indicates if the source file is a header file with no associated
implementation. This is set automatically based on the file extension and is used by CMake to
determine if certain dependency information should be computed.
KEEP_EXTENSION
Make the output file have the same extension as the source file.
If this property is set then the file extension of the output file will be the same as that of the
source file. Normally the output file extension is computed based on the language of the source
file, for example .cxx will go to a .o extension.
LABELS Specify a list of text labels associated with a source file.
This property has meaning only when the source file is listed in a target whose LABELS property is
also set. No other semantics are currently specified.
LANGUAGE
What programming language is the file.
A property that can be set to indicate what programming language the source file is. If it is not
set the language is determined based on the file extension. Typical values are CXX C etc. Setting
this property for a file means this file will be compiled. Do not set this for headers or files
that should not be compiled.
LOCATION
The full path to a source file.
A read only property on a SOURCE FILE that contains the full path to the source file.
MACOSX_PACKAGE_LOCATION
Place a source file inside a Mac OS X bundle, CFBundle, or framework.
Executable targets with the MACOSX_BUNDLE property set are built as Mac OS X application bundles
on Apple platforms. Shared library targets with the FRAMEWORK property set are built as Mac OS X
frameworks on Apple platforms. Module library targets with the BUNDLE property set are built as
Mac OS X CFBundle bundles on Apple platforms. Source files listed in the target with this
property set will be copied to a directory inside the bundle or framework content folder specified
by the property value. For bundles the content folder is "<name>.app/Contents". For frameworks
the content folder is "<name>.framework/Versions/<version>". For cfbundles the content folder is
"<name>.bundle/Contents" (unless the extension is changed). See the PUBLIC_HEADER,
PRIVATE_HEADER, and RESOURCE target properties for specifying files meant for Headers,
PrivateHeaders, or Resources directories.
OBJECT_DEPENDS
Additional files on which a compiled object file depends.
Specifies a semicolon-separated list of full-paths to files on which any object files compiled
from this source file depend. An object file will be recompiled if any of the named files is
newer than it.
This property need not be used to specify the dependency of a source file on a generated header
file that it includes. Although the property was originally introduced for this purpose, it is no
longer necessary. If the generated header file is created by a custom command in the same target
as the source file, the automatic dependency scanning process will recognize the dependency. If
the generated header file is created by another target, an inter-target dependency should be
created with the add_dependencies command (if one does not already exist due to linking
relationships).
OBJECT_OUTPUTS
Additional outputs for a Makefile rule.
Additional outputs created by compilation of this source file. If any of these outputs is missing
the object will be recompiled. This is supported only on Makefile generators and will be ignored
on other generators.
SYMBOLIC
Is this just a name for a rule.
If SYMBOLIC (boolean) is set to true the build system will be informed that the source file is not
actually created on disk but instead used as a symbolic name for a build rule.
WRAP_EXCLUDE
Exclude this source file from any code wrapping techniques.
Some packages can wrap source files into alternate languages to provide additional functionality.
For example, C++ code can be wrapped into Java or Python etc using SWIG etc. If WRAP_EXCLUDE is
set to true (1 etc) that indicates that this source file should not be wrapped.
PROPERTIES ON TARGETS
<CONFIG>_OUTPUT_NAME
Old per-configuration target file base name.
This is a configuration-specific version of OUTPUT_NAME. Use OUTPUT_NAME_<CONFIG> instead.
<CONFIG>_POSTFIX
Postfix to append to the target file name for configuration <CONFIG>.
When building with configuration <CONFIG> the value of this property is appended to the target
file name built on disk. For non-executable targets, this property is initialized by the value of
the variable CMAKE_<CONFIG>_POSTFIX if it is set when a target is created. This property is
ignored on the Mac for Frameworks and App Bundles.
<LANG>_VISIBILITY_PRESET
Value for symbol visibility compile flags
The <LANG>_VISIBILITY_PRESET property determines the value passed in a visibility related compile
option, such as -fvisibility= for <LANG>. This property only has an affect for libraries and
executables with exports. This property is initialized by the value of the variable
CMAKE_<LANG>_VISIBILITY_PRESET if it is set when a target is created.
ALIASED_TARGET
Name of target aliased by this target.
If this is an ALIAS target, this property contains the name of the target aliased.
ARCHIVE_OUTPUT_DIRECTORY
Output directory in which to build ARCHIVE target files.
This property specifies the directory into which archive target files should be built.
Multi-configuration generators (VS, Xcode) append a per-configuration subdirectory to the
specified directory. There are three kinds of target files that may be built: archive, library,
and runtime. Executables are always treated as runtime targets. Static libraries are always
treated as archive targets. Module libraries are always treated as library targets. For non-DLL
platforms shared libraries are treated as library targets. For DLL platforms the DLL part of a
shared library is treated as a runtime target and the corresponding import library is treated as
an archive target. All Windows-based systems including Cygwin are DLL platforms. This property is
initialized by the value of the variable CMAKE_ARCHIVE_OUTPUT_DIRECTORY if it is set when a target
is created.
ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>
Per-configuration output directory for ARCHIVE target files.
This is a per-configuration version of ARCHIVE_OUTPUT_DIRECTORY, but multi-configuration
generators (VS, Xcode) do NOT append a per-configuration subdirectory to the specified directory.
This property is initialized by the value of the variable CMAKE_ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>
if it is set when a target is created.
ARCHIVE_OUTPUT_NAME
Output name for ARCHIVE target files.
This property specifies the base name for archive target files. It overrides OUTPUT_NAME and
OUTPUT_NAME_<CONFIG> properties. There are three kinds of target files that may be built:
archive, library, and runtime. Executables are always treated as runtime targets. Static
libraries are always treated as archive targets. Module libraries are always treated as library
targets. For non-DLL platforms shared libraries are treated as library targets. For DLL platforms
the DLL part of a shared library is treated as a runtime target and the corresponding import
library is treated as an archive target. All Windows-based systems including Cygwin are DLL
platforms.
ARCHIVE_OUTPUT_NAME_<CONFIG>
Per-configuration output name for ARCHIVE target files.
This is the configuration-specific version of ARCHIVE_OUTPUT_NAME.
AUTOMOC
Should the target be processed with automoc (for Qt projects).
AUTOMOC is a boolean specifying whether CMake will handle the Qt moc preprocessor automatically,
i.e. without having to use the QT4_WRAP_CPP() or QT5_WRAP_CPP() macro. Currently Qt4 and Qt5 are
supported. When this property is set to TRUE, CMake will scan the source files at build time and
invoke moc accordingly. If an #include statement like #include "moc_foo.cpp" is found, the
Q_OBJECT class declaration is expected in the header, and moc is run on the header file. If an
#include statement like #include "foo.moc" is found, then a Q_OBJECT is expected in the current
source file and moc is run on the file itself. Additionally, all header files are parsed for
Q_OBJECT macros, and if found, moc is also executed on those files. The resulting moc files, which
are not included as shown above in any of the source files are included in a generated
<targetname>_automoc.cpp file, which is compiled as part of the target.This property is
initialized by the value of the variable CMAKE_AUTOMOC if it is set when a target is created.
Additional command line options for moc can be set via the AUTOMOC_MOC_OPTIONS property.
By setting the CMAKE_AUTOMOC_RELAXED_MODE variable to TRUE the rules for searching the files which
will be processed by moc can be relaxed. See the documentation for this variable for more details.
The global property AUTOMOC_TARGETS_FOLDER can be used to group the automoc targets together in an
IDE, e.g. in MSVS.
AUTOMOC_MOC_OPTIONS
Additional options for moc when using automoc (see the AUTOMOC property)
This property is only used if the AUTOMOC property is set to TRUE for this target. In this case,
it holds additional command line options which will be used when moc is executed during the build,
i.e. it is equivalent to the optional OPTIONS argument of the qt4_wrap_cpp() macro.
By default it is empty.
BUILD_WITH_INSTALL_RPATH
Should build tree targets have install tree rpaths.
BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the target in the build tree with
the INSTALL_RPATH. This takes precedence over SKIP_BUILD_RPATH and avoids the need for relinking
before installation. This property is initialized by the value of the variable
CMAKE_BUILD_WITH_INSTALL_RPATH if it is set when a target is created.
BUNDLE This target is a CFBundle on the Mac.
If a module library target has this property set to true it will be built as a CFBundle when built
on the mac. It will have the directory structure required for a CFBundle and will be suitable to
be used for creating Browser Plugins or other application resources.
BUNDLE_EXTENSION
The file extension used to name a BUNDLE target on the Mac.
The default value is "bundle" - you can also use "plugin" or whatever file extension is required
by the host app for your bundle.
COMPATIBLE_INTERFACE_BOOL
Properties which must be compatible with their link interface
The COMPATIBLE_INTERFACE_BOOL property may contain a list of propertiesfor this target which must
be consistent when evaluated as a boolean in the INTERFACE of all linked dependees. For example,
if a property "FOO" appears in the list, then for each dependee, the "INTERFACE_FOO" property
content in all of its dependencies must be consistent with each other, and with the "FOO" property
in the dependee. Consistency in this sense has the meaning that if the property is set, then it
must have the same boolean value as all others, and if the property is not set, then it is
ignored. Note that for each dependee, the set of properties from this property must not intersect
with the set of properties from the COMPATIBLE_INTERFACE_STRING property.
COMPATIBLE_INTERFACE_STRING
Properties which must be string-compatible with their link interface
The COMPATIBLE_INTERFACE_STRING property may contain a list of properties for this target which
must be the same when evaluated as a string in the INTERFACE of all linked dependees. For
example, if a property "FOO" appears in the list, then for each dependee, the "INTERFACE_FOO"
property content in all of its dependencies must be equal with each other, and with the "FOO"
property in the dependee. If the property is not set, then it is ignored. Note that for each
dependee, the set of properties from this property must not intersect with the set of properties
from the COMPATIBLE_INTERFACE_BOOL property.
COMPILE_DEFINITIONS
Preprocessor definitions for compiling a target's sources.
The COMPILE_DEFINITIONS property may be set to a semicolon-separated list of preprocessor
definitions using the syntax VAR or VAR=value. Function-style definitions are not supported.
CMake will automatically escape the value correctly for the native build system (note that CMake
language syntax may require escapes to specify some values). This property may be set on a
per-configuration basis using the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an
upper-case name (ex. "COMPILE_DEFINITIONS_DEBUG").
CMake will automatically drop some definitions that are not supported by the native build tool.
The VS6 IDE does not support definition values with spaces (but NMake does).
Contents of COMPILE_DEFINITIONS may use "generator expressions" with the syntax "$<...>".
Generator expressions are evaluated during build system generation to produce information specific
to each build configuration. Valid expressions are:
$<0:...> = empty string (ignores "...")
$<1:...> = content of "..."
$<CONFIG:cfg> = '1' if config is "cfg", else '0'
$<CONFIGURATION> = configuration name
$<BOOL:...> = '1' if the '...' is true, else '0'
$<STREQUAL:a,b> = '1' if a is STREQUAL b, else '0'
$<ANGLE-R> = A literal '>'. Used to compare strings which contain a '>' for example.
$<COMMA> = A literal ','. Used to compare strings which contain a ',' for example.
$<SEMICOLON> = A literal ';'. Used to prevent list expansion on an argument with ';'.
$<JOIN:list,...> = joins the list with the content of "..."
$<TARGET_NAME:...> = Marks ... as being the name of a target. This is required if exporting targets to multiple dependent export sets. The '...' must be a literal name of a target- it may not contain generator expressions.
$<INSTALL_INTERFACE:...> = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
$<BUILD_INTERFACE:...> = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
$<C_COMPILER_ID> = The CMake-id of the C compiler used.
$<C_COMPILER_ID:comp> = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
$<CXX_COMPILER_ID> = The CMake-id of the CXX compiler used.
$<CXX_COMPILER_ID:comp> = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
$<VERSION_GREATER:v1,v2> = '1' if v1 is a version greater than v2, else '0'.
$<VERSION_LESS:v1,v2> = '1' if v1 is a version less than v2, else '0'.
$<VERSION_EQUAL:v1,v2> = '1' if v1 is the same version as v2, else '0'.
$<C_COMPILER_VERSION> = The version of the C compiler used.
$<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
$<CXX_COMPILER_VERSION> = The version of the CXX compiler used.
$<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
$<TARGET_FILE:tgt> = main file (.exe, .so.1.2, .a)
$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
where "tgt" is the name of a target. Target file expressions produce a full path, but _DIR and
_NAME versions can produce the directory and file name components:
$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
$<TARGET_PROPERTY:tgt,prop> = The value of the property prop on the target tgt.
Note that tgt is not added as a dependency of the target this expression is evaluated on.
$<TARGET_POLICY:pol> = '1' if the policy was NEW when the 'head' target was created, else '0'. If the policy was not set, the warning message for the policy will be emitted. This generator expression only works for a subset of policies.
$<INSTALL_PREFIX> = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.
Boolean expressions:
$<AND:?[,?]...> = '1' if all '?' are '1', else '0'
$<OR:?[,?]...> = '0' if all '?' are '0', else '1'
$<NOT:?> = '0' if '?' is '1', else '1'
where '?' is always either '0' or '1'.
Expressions with an implicit 'this' target:
$<TARGET_PROPERTY:prop> = The value of the property prop on the target on which the generator expression is evaluated.
Disclaimer: Most native build tools have poor support for escaping certain values. CMake has
work-arounds for many cases but some values may just not be possible to pass correctly. If a
value does not seem to be escaped correctly, do not attempt to work-around the problem by adding
escape sequences to the value. Your work-around may break in a future version of CMake that has
improved escape support. Instead consider defining the macro in a (configured) header file. Then
report the limitation. Known limitations include:
# - broken almost everywhere
; - broken in VS IDE 7.0 and Borland Makefiles
, - broken in VS IDE
% - broken in some cases in NMake
& | - broken in some cases on MinGW
^ < > \" - broken in most Make tools on Windows
CMake does not reject these values outright because they do work in some cases. Use with caution.
COMPILE_DEFINITIONS_<CONFIG>
Per-configuration preprocessor definitions on a target.
This is the configuration-specific version of COMPILE_DEFINITIONS.
COMPILE_FLAGS
Additional flags to use when compiling this target's sources.
The COMPILE_FLAGS property sets additional compiler flags used to build sources within the target.
Use COMPILE_DEFINITIONS to pass additional preprocessor definitions.
COMPILE_OPTIONS
List of options to pass to the compiler.
This property specifies the list of options specified so far for this property. This property
exists on directories and targets.
The target property values are used by the generators to set the options for the compiler.
Contents of COMPILE_OPTIONS may use "generator expressions" with the syntax "$<...>". Generator
expressions are evaluated during build system generation to produce information specific to each
build configuration. Valid expressions are:
$<0:...> = empty string (ignores "...")
$<1:...> = content of "..."
$<CONFIG:cfg> = '1' if config is "cfg", else '0'
$<CONFIGURATION> = configuration name
$<BOOL:...> = '1' if the '...' is true, else '0'
$<STREQUAL:a,b> = '1' if a is STREQUAL b, else '0'
$<ANGLE-R> = A literal '>'. Used to compare strings which contain a '>' for example.
$<COMMA> = A literal ','. Used to compare strings which contain a ',' for example.
$<SEMICOLON> = A literal ';'. Used to prevent list expansion on an argument with ';'.
$<JOIN:list,...> = joins the list with the content of "..."
$<TARGET_NAME:...> = Marks ... as being the name of a target. This is required if exporting targets to multiple dependent export sets. The '...' must be a literal name of a target- it may not contain generator expressions.
$<INSTALL_INTERFACE:...> = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
$<BUILD_INTERFACE:...> = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
$<C_COMPILER_ID> = The CMake-id of the C compiler used.
$<C_COMPILER_ID:comp> = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
$<CXX_COMPILER_ID> = The CMake-id of the CXX compiler used.
$<CXX_COMPILER_ID:comp> = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
$<VERSION_GREATER:v1,v2> = '1' if v1 is a version greater than v2, else '0'.
$<VERSION_LESS:v1,v2> = '1' if v1 is a version less than v2, else '0'.
$<VERSION_EQUAL:v1,v2> = '1' if v1 is the same version as v2, else '0'.
$<C_COMPILER_VERSION> = The version of the C compiler used.
$<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
$<CXX_COMPILER_VERSION> = The version of the CXX compiler used.
$<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
$<TARGET_FILE:tgt> = main file (.exe, .so.1.2, .a)
$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
where "tgt" is the name of a target. Target file expressions produce a full path, but _DIR and
_NAME versions can produce the directory and file name components:
$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
$<TARGET_PROPERTY:tgt,prop> = The value of the property prop on the target tgt.
Note that tgt is not added as a dependency of the target this expression is evaluated on.
$<TARGET_POLICY:pol> = '1' if the policy was NEW when the 'head' target was created, else '0'. If the policy was not set, the warning message for the policy will be emitted. This generator expression only works for a subset of policies.
$<INSTALL_PREFIX> = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.
Boolean expressions:
$<AND:?[,?]...> = '1' if all '?' are '1', else '0'
$<OR:?[,?]...> = '0' if all '?' are '0', else '1'
$<NOT:?> = '0' if '?' is '1', else '1'
where '?' is always either '0' or '1'.
Expressions with an implicit 'this' target:
$<TARGET_PROPERTY:prop> = The value of the property prop on the target on which the generator expression is evaluated.
DEBUG_POSTFIX
See target property <CONFIG>_POSTFIX.
This property is a special case of the more-general <CONFIG>_POSTFIX property for the DEBUG
configuration.
DEFINE_SYMBOL
Define a symbol when compiling this target's sources.
DEFINE_SYMBOL sets the name of the preprocessor symbol defined when compiling sources in a shared
library. If not set here then it is set to target_EXPORTS by default (with some substitutions if
the target is not a valid C identifier). This is useful for headers to know whether they are being
included from inside their library or outside to properly setup dllexport/dllimport decorations.
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
Mac 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.
EXCLUDE_FROM_ALL
Exclude the target from the all target.
A property on a target that indicates if the target is excluded from the default build target. If
it is not, then with a Makefile for example typing make will cause this target to be built. The
same concept applies to the default build of other generators. Installing a target with
EXCLUDE_FROM_ALL set to true has undefined behavior.
EXCLUDE_FROM_DEFAULT_BUILD
Exclude target from "Build Solution".
This property is only used by Visual Studio generators 7 and above. When set to TRUE, the target
will not be built when you press "Build Solution".
EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG>
Per-configuration version of target exclusion from "Build Solution".
This is the configuration-specific version of EXCLUDE_FROM_DEFAULT_BUILD. If the generic
EXCLUDE_FROM_DEFAULT_BUILD is also set on a target, EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG> takes
precedence in configurations for which it has a value.
EXPORT_NAME
Exported name for target files.
This sets the name for the IMPORTED target generated when it this target is is exported. If not
set, the logical target name is used by default.
EchoString
A message to be displayed when the target is built.
A message to display on some generators (such as makefiles) when the target is built.
FOLDER Set the folder name. Use to organize targets in an IDE.
Targets with no FOLDER property will appear as top level entities in IDEs like Visual Studio.
Targets with the same FOLDER property value will appear next to each other in a folder of that
name. To nest folders, use FOLDER values such as 'GUI/Dialogs' with '/' characters separating
folder levels.
FRAMEWORK
This target is a framework on the Mac.
If a shared library target has this property set to true it will be built as a framework when
built on the mac. It will have the directory structure required for a framework and will be
suitable to be used with the -framework option
Fortran_FORMAT
Set to FIXED or FREE to indicate the Fortran source layout.
This property tells CMake whether the Fortran source files in a target use fixed-format or
free-format. CMake will pass the corresponding format flag to the compiler. Use the
source-specific Fortran_FORMAT property to change the format of a specific source file. If the
variable CMAKE_Fortran_FORMAT is set when a target is created its value is used to initialize this
property.
Fortran_MODULE_DIRECTORY
Specify output directory for Fortran modules provided by the target.
If the target contains Fortran source files that provide modules and the compiler supports a
module output directory this specifies the directory in which the modules will be placed. When
this property is not set the modules will be placed in the build directory corresponding to the
target's source directory. If the variable CMAKE_Fortran_MODULE_DIRECTORY is set when a target is
created its value is used to initialize this property.
Note that some compilers will automatically search the module output directory for modules USEd
during compilation but others will not. If your sources USE modules their location must be
specified by INCLUDE_DIRECTORIES regardless of this property.
GENERATOR_FILE_NAME
Generator's file for this target.
An internal property used by some generators to record the name of the project or dsp file
associated with this target. Note that at configure time, this property is only set for targets
created by include_external_msproject().
GNUtoMS
Convert GNU import library (.dll.a) to MS format (.lib).
When linking a shared library or executable that exports symbols using GNU tools on Windows
(MinGW/MSYS) with Visual Studio installed convert the import library (.dll.a) from GNU to MS
format (.lib). Both import libraries will be installed by install(TARGETS) and exported by
install(EXPORT) and export() to be linked by applications with either GNU- or MS-compatible tools.
If the variable CMAKE_GNUtoMS is set when a target is created its value is used to initialize this
property. The variable must be set prior to the first command that enables a language such as
project() or enable_language(). CMake provides the variable as an option to the user
automatically when configuring on Windows with GNU tools.
HAS_CXX
Link the target using the C++ linker tool (obsolete).
This is equivalent to setting the LINKER_LANGUAGE property to CXX. See that property's
documentation for details.
IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
Specify #include line transforms for dependencies in a target.
This property specifies rules to transform macro-like #include lines during implicit dependency
scanning of C and C++ source files. The list of rules must be semicolon-separated with each entry
of the form "A_MACRO(%)=value-with-%" (the % must be literal). During dependency scanning
occurrences of A_MACRO(...) on #include lines will be replaced by the value given with the macro
argument substituted for '%'. For example, the entry
MYDIR(%)=<mydir/%>
will convert lines of the form
#include MYDIR(myheader.h)
to
#include <mydir/myheader.h>
allowing the dependency to be followed.
This property applies to sources in the target on which it is set.
IMPORTED
Read-only indication of whether a target is IMPORTED.
The boolean value of this property is true for targets created with the IMPORTED option to
add_executable or add_library. It is false for targets built within the project.
IMPORTED_CONFIGURATIONS
Configurations provided for an IMPORTED target.
Set this to the list of configuration names available for an IMPORTED target. The names
correspond to configurations defined in the project from which the target is imported. If the
importing project uses a different set of configurations the names may be mapped using the
MAP_IMPORTED_CONFIG_<CONFIG> property. Ignored for non-imported targets.
IMPORTED_IMPLIB
Full path to the import library for an IMPORTED target.
Set this to the location of the ".lib" part of a windows DLL. Ignored for non-imported targets.
IMPORTED_IMPLIB_<CONFIG>
<CONFIG>-specific version of IMPORTED_IMPLIB property.
Configuration names correspond to those provided by the project from which the target is imported.
IMPORTED_LINK_DEPENDENT_LIBRARIES
Dependent shared libraries of an imported shared library.
Shared libraries may be linked to other shared libraries as part of their implementation. On some
platforms the linker searches for the dependent libraries of shared libraries they are including
in the link. Set this property to the list of dependent shared libraries of an imported library.
The list should be disjoint from the list of interface libraries in the INTERFACE_LINK_LIBRARIES
property. On platforms requiring dependent shared libraries to be found at link time CMake uses
this list to add appropriate files or paths to the link command line. Ignored for non-imported
targets.
IMPORTED_LINK_DEPENDENT_LIBRARIES_<CONFIG>
<CONFIG>-specific version of IMPORTED_LINK_DEPENDENT_LIBRARIES.
Configuration names correspond to those provided by the project from which the target is imported.
If set, this property completely overrides the generic property for the named configuration.
IMPORTED_LINK_INTERFACE_LANGUAGES
Languages compiled into an IMPORTED static library.
Set this to the list of languages of source files compiled to produce a STATIC IMPORTED library
(such as "C" or "CXX"). CMake accounts for these languages when computing how to link a target to
the imported library. For example, when a C executable links to an imported C++ static library
CMake chooses the C++ linker to satisfy language runtime dependencies of the static library.
This property is ignored for targets that are not STATIC libraries. This property is ignored for
non-imported targets.
IMPORTED_LINK_INTERFACE_LANGUAGES_<CONFIG>
<CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LANGUAGES.
Configuration names correspond to those provided by the project from which the target is imported.
If set, this property completely overrides the generic property for the named configuration.
IMPORTED_LINK_INTERFACE_LIBRARIES
Transitive link interface of an IMPORTED target.
Set this to the list of libraries whose interface is included when an IMPORTED library target is
linked to another target. The libraries will be included on the link line for the target. Unlike
the LINK_INTERFACE_LIBRARIES property, this property applies to all imported target types,
including STATIC libraries. This property is ignored for non-imported targets.
This property is ignored if the target also has a non-empty INTERFACE_LINK_LIBRARIES property.
This property is deprecated. Use INTERFACE_LINK_LIBRARIES instead.
IMPORTED_LINK_INTERFACE_LIBRARIES_<CONFIG>
<CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LIBRARIES.
Configuration names correspond to those provided by the project from which the target is imported.
If set, this property completely overrides the generic property for the named configuration.
This property is ignored if the target also has a non-empty INTERFACE_LINK_LIBRARIES property.
This property is deprecated. Use INTERFACE_LINK_LIBRARIES instead.
IMPORTED_LINK_INTERFACE_MULTIPLICITY
Repetition count for cycles of IMPORTED static libraries.
This is LINK_INTERFACE_MULTIPLICITY for IMPORTED targets.
IMPORTED_LINK_INTERFACE_MULTIPLICITY_<CONFIG>
<CONFIG>-specific version of IMPORTED_LINK_INTERFACE_MULTIPLICITY.
If set, this property completely overrides the generic property for the named configuration.
IMPORTED_LOCATION
Full path to the main file on disk for an IMPORTED target.
Set this to the location of an IMPORTED target file on disk. For executables this is the location
of the executable file. For bundles on OS X this is the location of the executable file inside
Contents/MacOS under the application bundle folder. For static libraries and modules this is the
location of the library or module. For shared libraries on non-DLL platforms this is the location
of the shared library. For frameworks on OS X this is the location of the library file symlink
just inside the framework folder. For DLLs this is the location of the ".dll" part of the
library. For UNKNOWN libraries this is the location of the file to be linked. Ignored for
non-imported targets.
Projects may skip IMPORTED_LOCATION if the configuration-specific property
IMPORTED_LOCATION_<CONFIG> is set. To get the location of an imported target read one of the
LOCATION or LOCATION_<CONFIG> properties.
IMPORTED_LOCATION_<CONFIG>
<CONFIG>-specific version of IMPORTED_LOCATION property.
Configuration names correspond to those provided by the project from which the target is imported.
IMPORTED_NO_SONAME
Specifies that an IMPORTED shared library target has no "soname".
Set this property to true for an imported shared library file that has no "soname" field. CMake
may adjust generated link commands for some platforms to prevent the linker from using the path to
the library in place of its missing soname. Ignored for non-imported targets.
IMPORTED_NO_SONAME_<CONFIG>
<CONFIG>-specific version of IMPORTED_NO_SONAME property.
Configuration names correspond to those provided by the project from which the target is imported.
IMPORTED_SONAME
The "soname" of an IMPORTED target of shared library type.
Set this to the "soname" embedded in an imported shared library. This is meaningful only on
platforms supporting the feature. Ignored for non-imported targets.
IMPORTED_SONAME_<CONFIG>
<CONFIG>-specific version of IMPORTED_SONAME property.
Configuration names correspond to those provided by the project from which the target is imported.
IMPORT_PREFIX
What comes before the import library name.
Similar to the target property PREFIX, but used for import libraries (typically corresponding to a
DLL) instead of regular libraries. A target property that can be set to override the prefix (such
as "lib") on an import library name.
IMPORT_SUFFIX
What comes after the import library name.
Similar to the target property SUFFIX, but used for import libraries (typically corresponding to a
DLL) instead of regular libraries. A target property that can be set to override the suffix (such
as ".lib") on an import library name.
INCLUDE_DIRECTORIES
List of preprocessor include file search directories.
This property specifies the list of directories given so far to the include_directories command.
This property exists on directories and targets. In addition to accepting values from the
include_directories command, values may be set directly on any directory or any target using the
set_property command. A target gets its initial value for this property from the value of the
directory property. A directory gets its initial value from its parent directory if it has one.
Both directory and target property values are adjusted by calls to the include_directories
command.
The target property values are used by the generators to set the include paths for the compiler.
See also the include_directories command.
Contents of INCLUDE_DIRECTORIES may use "generator expressions" with the syntax "$<...>".
Generator expressions are evaluated during build system generation to produce information specific
to each build configuration. Valid expressions are:
$<0:...> = empty string (ignores "...")

INTERFACE_POSITION_INDEPENDENT_CODE
Whether consumers need to create a position-independent target
The INTERFACE_POSITION_INDEPENDENT_CODE property informs consumers of this target whether they
must set their POSITION_INDEPENDENT_CODE property to ON. If this property is set to ON, then the
POSITION_INDEPENDENT_CODE property on all consumers will be set to ON. Similarly, if this
property is set to OFF, then the POSITION_INDEPENDENT_CODE property on all consumers will be set
to OFF. If this property is undefined, then consumers will determine their
POSITION_INDEPENDENT_CODE property by other means. Consumers must ensure that the targets that
they link to have a consistent requirement for their INTERFACE_POSITION_INDEPENDENT_CODE property.
INTERFACE_SYSTEM_INCLUDE_DIRECTORIES
List of public system include directories for a library.
Targets may populate this property to publish the include directories which contain system
headers, and therefore should not result in compiler warnings. Consuming targets will then mark
the same include directories as system headers.

$<TARGET_FILE:tgt> = main file (.exe, .so.1.2, .a)
$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
where "tgt" is the name of a target. Target file expressions produce a full path, but _DIR and
_NAME versions can produce the directory and file name components:
$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
$<TARGET_PROPERTY:tgt,prop> = The value of the property prop on the target tgt.
Note that tgt is not added as a dependency of the target this expression is evaluated on.
$<TARGET_POLICY:pol> = '1' if the policy was NEW when the 'head' target was created, else '0'. If the policy was not set, the warning message for the policy will be emitted. This generator expression only works for a subset of policies.
$<INSTALL_PREFIX> = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.
Boolean expressions:
$<AND:?[,?]...> = '1' if all '?' are '1', else '0'
$<OR:?[,?]...> = '0' if all '?' are '0', else '1'
$<NOT:?> = '0' if '?' is '1', else '1'
where '?' is always either '0' or '1'.
Expressions with an implicit 'this' target:
$<TARGET_PROPERTY:prop> = The value of the property prop on the target on which the generator expression is evaluated.
INTERPROCEDURAL_OPTIMIZATION
Enable interprocedural optimization for a target.
If set to true, enables interprocedural optimizations if they are known to be supported by the
compiler.
INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
Per-configuration interprocedural optimization for a target.
This is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION. If set, this property
overrides the generic property for the named configuration.
LABELS Specify a list of text labels associated with a target.
Target label semantics are currently unspecified.
LIBRARY_OUTPUT_DIRECTORY
Output directory in which to build LIBRARY target files.
This property specifies the directory into which library target files should be built.
Multi-configuration generators (VS, Xcode) append a per-configuration subdirectory to the
specified directory. There are three kinds of target files that may be built: archive, library,
and runtime. Executables are always treated as runtime targets. Static libraries are always
treated as archive targets. Module libraries are always treated as library targets. For non-DLL
platforms shared libraries are treated as library targets. For DLL platforms the DLL part of a
shared library is treated as a runtime target and the corresponding import library is treated as
an archive target. All Windows-based systems including Cygwin are DLL platforms. This property is
initialized by the value of the variable CMAKE_LIBRARY_OUTPUT_DIRECTORY if it is set when a target
is created.
LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
Per-configuration output directory for LIBRARY target files.
This is a per-configuration version of LIBRARY_OUTPUT_DIRECTORY, but multi-configuration
generators (VS, Xcode) do NOT append a per-configuration subdirectory to the specified directory.
This property is initialized by the value of the variable CMAKE_LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
if it is set when a target is created.
LIBRARY_OUTPUT_NAME
Output name for LIBRARY target files.
This property specifies the base name for library target files. It overrides OUTPUT_NAME and
OUTPUT_NAME_<CONFIG> properties. There are three kinds of target files that may be built:
archive, library, and runtime. Executables are always treated as runtime targets. Static
libraries are always treated as archive targets. Module libraries are always treated as library
targets. For non-DLL platforms shared libraries are treated as library targets. For DLL platforms
the DLL part of a shared library is treated as a runtime target and the corresponding import
library is treated as an archive target. All Windows-based systems including Cygwin are DLL
platforms.
LIBRARY_OUTPUT_NAME_<CONFIG>
Per-configuration output name for LIBRARY target files.
This is the configuration-specific version of LIBRARY_OUTPUT_NAME.
LINKER_LANGUAGE
Specifies language whose compiler will invoke the linker.
For executables, shared libraries, and modules, this sets the language whose compiler is used to
link the target (such as "C" or "CXX"). A typical value for an executable is the language of the
source file providing the program entry point (main). If not set, the language with the highest
linker preference value is the default. See documentation of CMAKE_<LANG>_LINKER_PREFERENCE
variables.
If this property is not set by the user, it will be calculated at generate-time by CMake.
LINK_DEPENDS
Additional files on which a target binary depends for linking.
Specifies a semicolon-separated list of full-paths to files on which the link rule for this target
depends. The target binary will be linked if any of the named files is newer than it.
This property is ignored by non-Makefile generators. It is intended to specify dependencies on
"linker scripts" for custom Makefile link rules.
LINK_DEPENDS_NO_SHARED
Do not depend on linked shared library files.
Set this property to true to tell CMake generators not to add file-level dependencies on the
shared library files linked by this target. Modification to the shared libraries will not be
sufficient to re-link this target. Logical target-level dependencies will not be affected so the
linked shared libraries will still be brought up to date before this target is built.
This property is initialized by the value of the variable CMAKE_LINK_DEPENDS_NO_SHARED if it is
set when a target is created.
LINK_FLAGS
Additional flags to use when linking this target.
The LINK_FLAGS property can be used to add extra flags to the link step of a target.
LINK_FLAGS_<CONFIG> will add to the configuration <CONFIG>, for example, DEBUG, RELEASE,
MINSIZEREL, RELWITHDEBINFO.
LINK_FLAGS_<CONFIG>
Per-configuration linker flags for a target.
This is the configuration-specific version of LINK_FLAGS.
LINK_INTERFACE_LIBRARIES
List public interface libraries for a shared library or executable.
By default linking to a shared library target transitively links to targets with which the library
itself was linked. For an executable with exports (see the ENABLE_EXPORTS property) no default
transitive link dependencies are used. This property replaces the default transitive link
dependencies with an explicit list. When the target is linked into another target the libraries
listed (and recursively their link interface libraries) will be provided to the other target also.
If the list is empty then no transitive link dependencies will be incorporated when this target is
linked into another target even if the default set is non-empty. This property is initialized by
the value of the variable CMAKE_LINK_INTERFACE_LIBRARIES if it is set when a target is created.
This property is ignored for STATIC libraries.
This property is overridden by the INTERFACE_LINK_LIBRARIES property if policy CMP0022 is NEW.
This property is deprecated. Use INTERFACE_LINK_LIBRARIES instead.
LINK_INTERFACE_LIBRARIES_<CONFIG>
Per-configuration list of public interface libraries for a target.
This is the configuration-specific version of LINK_INTERFACE_LIBRARIES. If set, this property
completely overrides the generic property for the named configuration.
This property is overridden by the INTERFACE_LINK_LIBRARIES property if policy CMP0022 is NEW.
This property is deprecated. Use INTERFACE_LINK_LIBRARIES instead.
LINK_INTERFACE_MULTIPLICITY
Repetition count for STATIC libraries with cyclic dependencies.
When linking to a STATIC library target with cyclic dependencies the linker may need to scan more
than once through the archives in the strongly connected component of the dependency graph. CMake
by default constructs the link line so that the linker will scan through the component at least
twice. This property specifies the minimum number of scans if it is larger than the default.
CMake uses the largest value specified by any target in a component.
LINK_INTERFACE_MULTIPLICITY_<CONFIG>
Per-configuration repetition count for cycles of STATIC libraries.
This is the configuration-specific version of LINK_INTERFACE_MULTIPLICITY. If set, this property
completely overrides the generic property for the named configuration.
LINK_LIBRARIES
List of direct link dependencies.
This property specifies the list of libraries or targets which will be used for linking. In
addition to accepting values from the target_link_libraries command, values may be set directly on
any target using the set_property command.
The target property values are used by the generators to set the link libraries for the compiler.
See also the target_link_libraries command.
Contents of LINK_LIBRARIES may use "generator expressions" with the syntax "$<...>". Generator
expressions are evaluated during build system generation to produce information specific to each
build configuration. Valid expressions are:
$<0:...> = empty string (ignores "...")
$<1:...> = content of "..."
$<CONFIG:cfg> = '1' if config is "cfg", else '0'
$<CONFIGURATION> = configuration name
$<BOOL:...> = '1' if the '...' is true, else '0'
$<STREQUAL:a,b> = '1' if a is STREQUAL b, else '0'
$<ANGLE-R> = A literal '>'. Used to compare strings which contain a '>' for example.
$<COMMA> = A literal ','. Used to compare strings which contain a ',' for example.
$<SEMICOLON> = A literal ';'. Used to prevent list expansion on an argument with ';'.
$<JOIN:list,...> = joins the list with the content of "..."
$<TARGET_NAME:...> = Marks ... as being the name of a target. This is required if exporting targets to multiple dependent export sets. The '...' must be a literal name of a target- it may not contain generator expressions.
$<INSTALL_INTERFACE:...> = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
$<BUILD_INTERFACE:...> = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
$<C_COMPILER_ID> = The CMake-id of the C compiler used.
$<C_COMPILER_ID:comp> = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
$<CXX_COMPILER_ID> = The CMake-id of the CXX compiler used.
$<CXX_COMPILER_ID:comp> = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
$<VERSION_GREATER:v1,v2> = '1' if v1 is a version greater than v2, else '0'.
$<VERSION_LESS:v1,v2> = '1' if v1 is a version less than v2, else '0'.
$<VERSION_EQUAL:v1,v2> = '1' if v1 is the same version as v2, else '0'.
$<C_COMPILER_VERSION> = The version of the C compiler used.
$<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
$<CXX_COMPILER_VERSION> = The version of the CXX compiler used.
$<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
$<TARGET_FILE:tgt> = main file (.exe, .so.1.2, .a)
$<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
$<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
where "tgt" is the name of a target. Target file expressions produce a full path, but _DIR and
_NAME versions can produce the directory and file name components:
$<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
$<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
$<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
$<TARGET_PROPERTY:tgt,prop> = The value of the property prop on the target tgt.
Note that tgt is not added as a dependency of the target this expression is evaluated on.
$<TARGET_POLICY:pol> = '1' if the policy was NEW when the 'head' target was created, else '0'. If the policy was not set, the warning message for the policy will be emitted. This generator expression only works for a subset of policies.
$<INSTALL_PREFIX> = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.
Boolean expressions:
$<AND:?[,?]...> = '1' if all '?' are '1', else '0'
$<OR:?[,?]...> = '0' if all '?' are '0', else '1'
$<NOT:?> = '0' if '?' is '1', else '1'
where '?' is always either '0' or '1'.
Expressions with an implicit 'this' target:
$<TARGET_PROPERTY:prop> = The value of the property prop on the target on which the generator expression is evaluated.
LINK_SEARCH_END_STATIC
End a link line such that static system libraries are used.
Some linkers support switches such as -Bstatic and -Bdynamic to determine whether to use static or
shared libraries for -lXXX options. CMake uses these options to set the link type for libraries
whose full paths are not known or (in some cases) are in implicit link directories for the
platform. By default CMake adds an option at the end of the library list (if necessary) to set
the linker search type back to its starting type. This property switches the final linker search
type to -Bstatic regardless of how it started. See also LINK_SEARCH_START_STATIC.
LINK_SEARCH_START_STATIC
Assume the linker looks for static libraries by default.
Some linkers support switches such as -Bstatic and -Bdynamic to determine whether to use static or
shared libraries for -lXXX options. CMake uses these options to set the link type for libraries
whose full paths are not known or (in some cases) are in implicit link directories for the
platform. By default the linker search type is assumed to be -Bdynamic at the beginning of the
library list. This property switches the assumption to -Bstatic. It is intended for use when
linking an executable statically (e.g. with the GNU -static option). See also
LINK_SEARCH_END_STATIC.
LOCATION
Read-only location of a target on disk.
For an imported target, this read-only property returns the value of the LOCATION_<CONFIG>
property for an unspecified configuration <CONFIG> provided by the target.
For a non-imported target, this property is provided for compatibility with CMake 2.4 and below.
It was meant to get the location of an executable target's output file for use in
add_custom_command. The path may contain a build-system-specific portion that is replaced at
build time with the configuration getting built (such as "$(ConfigurationName)" in VS). In CMake
2.6 and above add_custom_command automatically recognizes a target name in its COMMAND and DEPENDS
options and computes the target location. In CMake 2.8.4 and above add_custom_command recognizes
generator expressions to refer to target locations anywhere in the command. Therefore this
property is not needed for creating custom commands.
Do not set properties that affect the location of a target after reading this property. These
include properties whose names match
"(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?", "(IMPLIB_)?(PREFIX|SUFFIX)", or
"LINKER_LANGUAGE". Failure to follow this rule is not diagnosed and leaves the location of the
target undefined.
LOCATION_<CONFIG>
Read-only property providing a target location on disk.
A read-only property that indicates where a target's main file is located on disk for the
configuration <CONFIG>. The property is defined only for library and executable targets. An
imported target may provide a set of configurations different from that of the importing project.
By default CMake looks for an exact-match but otherwise uses an arbitrary available configuration.
Use the MAP_IMPORTED_CONFIG_<CONFIG> property to map imported configurations explicitly.
Do not set properties that affect the location of a target after reading this property. These
include properties whose names match
"(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?", "(IMPLIB_)?(PREFIX|SUFFIX)", or
"LINKER_LANGUAGE". Failure to follow this rule is not diagnosed and leaves the location of the
target undefined.
MACOSX_BUNDLE
Build an executable as an application bundle on Mac OS X.
When this property is set to true the executable when built on Mac OS X will be created as an
application bundle. This makes it a GUI executable that can be launched from the Finder. See the
MACOSX_BUNDLE_INFO_PLIST target property for information about creation of the Info.plist file for
the application bundle. This property is initialized by the value of the variable
CMAKE_MACOSX_BUNDLE if it is set when a target is created.
MACOSX_BUNDLE_INFO_PLIST
Specify a custom Info.plist template for a Mac OS X App Bundle.
An executable target with MACOSX_BUNDLE enabled will be built as an application bundle on Mac OS
X. By default its Info.plist file is created by configuring a template called
MacOSXBundleInfo.plist.in located in the CMAKE_MODULE_PATH. This property specifies an
alternative template file name which may be a full path.
The following target properties may be set to specify content to be configured into the file:
MACOSX_BUNDLE_INFO_STRING
MACOSX_BUNDLE_ICON_FILE
MACOSX_BUNDLE_GUI_IDENTIFIER
MACOSX_BUNDLE_LONG_VERSION_STRING
MACOSX_BUNDLE_BUNDLE_NAME
MACOSX_BUNDLE_SHORT_VERSION_STRING
MACOSX_BUNDLE_BUNDLE_VERSION
MACOSX_BUNDLE_COPYRIGHT
CMake variables of the same name may be set to affect all targets in a directory that do not have
each specific property set. If a custom Info.plist is specified by this property it may of course
hard-code all the settings instead of using the target properties.
MACOSX_FRAMEWORK_INFO_PLIST
Specify a custom Info.plist template for a Mac OS X Framework.
A library target with FRAMEWORK enabled will be built as a framework on Mac OS X. By default its
Info.plist file is created by configuring a template called MacOSXFrameworkInfo.plist.in located
in the CMAKE_MODULE_PATH. This property specifies an alternative template file name which may be
a full path.
The following target properties may be set to specify content to be configured into the file:
MACOSX_FRAMEWORK_ICON_FILE
MACOSX_FRAMEWORK_IDENTIFIER
MACOSX_FRAMEWORK_SHORT_VERSION_STRING
MACOSX_FRAMEWORK_BUNDLE_VERSION
CMake variables of the same name may be set to affect all targets in a directory that do not have
each specific property set. If a custom Info.plist is specified by this property it may of course
hard-code all the settings instead of using the target properties.
MACOSX_RPATH
Whether to use rpaths on Mac OS X.
When this property is set to true, the directory portion of the"install_name" field of shared
libraries will default to "@rpath".Runtime paths will also be embedded in binaries using this
target.This property is initialized by the value of the variable CMAKE_MACOSX_RPATH if it is set
when a target is created.
MAP_IMPORTED_CONFIG_<CONFIG>
Map from project configuration to IMPORTED target's configuration.
Set this to the list of configurations of an imported target that may be used for the current
project's <CONFIG> configuration. Targets imported from another project may not provide the same
set of configuration names available in the current project. Setting this property tells CMake
what imported configurations are suitable for use when building the <CONFIG> configuration. The
first configuration in the list found to be provided by the imported target is selected. If this
property is set and no matching configurations are available, then the imported target is
considered to be not found. This property is ignored for non-imported targets.
NAME Logical name for the target.
Read-only logical name for the target as used by CMake.
NO_SONAME
Whether to set "soname" when linking a shared library or module.
Enable this boolean property if a generated shared library or module should not have "soname" set.
Default is to set "soname" on all shared libraries and modules as long as the platform supports
it. Generally, use this property only for leaf private libraries or plugins. If you use it on
normal shared libraries which other targets link against, on some platforms a linker will insert a
full path to the library (as specified at link time) into the dynamic section of the dependent
binary. Therefore, once installed, dynamic loader may eventually fail to locate the library for
the binary.
OSX_ARCHITECTURES
Target specific architectures for OS X.
The OSX_ARCHITECTURES property sets the target binary architecture for targets on OS X. This
property is initialized by the value of the variable CMAKE_OSX_ARCHITECTURES if it is set when a
target is created. Use OSX_ARCHITECTURES_<CONFIG> to set the binary architectures on a
per-configuration basis. <CONFIG> is an upper-case name (ex: "OSX_ARCHITECTURES_DEBUG").
OSX_ARCHITECTURES_<CONFIG>
Per-configuration OS X binary architectures for a target.
This property is the configuration-specific version of OSX_ARCHITECTURES.
OUTPUT_NAME
Output name for target files.
This sets the base name for output files created for an executable or library target. If not set,
the logical target name is used by default.
OUTPUT_NAME_<CONFIG>
Per-configuration target file base name.
This is the configuration-specific version of OUTPUT_NAME.
PDB_NAME
Output name for MS debug symbols .pdb file from linker.
Set the base name for debug symbols file created for an executable or shared library target. If
not set, the logical target name is used by default.
This property is not implemented by the Visual Studio 6 generator.
PDB_NAME_<CONFIG>
Per-configuration name for MS debug symbols .pdb file.
This is the configuration-specific version of PDB_NAME.
This property is not implemented by the Visual Studio 6 generator.
PDB_OUTPUT_DIRECTORY
Output directory for MS debug symbols .pdb file from linker.
This property specifies the directory into which the MS debug symbols will be placed by the
linker. This property is initialized by the value of the variable CMAKE_PDB_OUTPUT_DIRECTORY if
it is set when a target is created.
This property is not implemented by the Visual Studio 6 generator.
PDB_OUTPUT_DIRECTORY_<CONFIG>
Per-configuration output directory for MS debug symbols .pdb files.
This is a per-configuration version of PDB_OUTPUT_DIRECTORY, but multi-configuration generators
(VS, Xcode) do NOT append a per-configuration subdirectory to the specified directory. This
property is initialized by the value of the variable CMAKE_PDB_OUTPUT_DIRECTORY_<CONFIG> if it is
set when a target is created.
This property is not implemented by the Visual Studio 6 generator.
POSITION_INDEPENDENT_CODE
Whether to create a position-independent target
The POSITION_INDEPENDENT_CODE property determines whether position independent executables or
shared libraries will be created. This property is true by default for SHARED and MODULE library
targets and false otherwise. This property is initialized by the value of the variable
CMAKE_POSITION_INDEPENDENT_CODE if it is set when a target is created.
POST_INSTALL_SCRIPT
Deprecated install support.
The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old way to specify CMake scripts
to run before and after installing a target. They are used only when the old INSTALL_TARGETS
command is used to install the target. Use the INSTALL command instead.
PREFIX What comes before the library name.
A target property that can be set to override the prefix (such as "lib") on a library name.
PRE_INSTALL_SCRIPT
Deprecated install support.
The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old way to specify CMake scripts
to run before and after installing a target. They are used only when the old INSTALL_TARGETS
command is used to install the target. Use the INSTALL command instead.
PRIVATE_HEADER
Specify private header files in a FRAMEWORK shared library target.
Shared library targets marked with the FRAMEWORK property generate frameworks on OS X and normal
shared libraries on other platforms. This property may be set to a list of header files to be
placed in the PrivateHeaders directory inside the framework folder. On non-Apple platforms these
headers may be installed using the PRIVATE_HEADER option to the install(TARGETS) command.
PROJECT_LABEL
Change the name of a target in an IDE.
Can be used to change the name of the target in an IDE like Visual Studio.
PUBLIC_HEADER
Specify public header files in a FRAMEWORK shared library target.
Shared library targets marked with the FRAMEWORK property generate frameworks on OS X and normal
shared libraries on other platforms. This property may be set to a list of header files to be
placed in the Headers directory inside the framework folder. On non-Apple platforms these headers
may be installed using the PUBLIC_HEADER option to the install(TARGETS) command.
RESOURCE
Specify resource files in a FRAMEWORK shared library target.
Shared library targets marked with the FRAMEWORK property generate frameworks on OS X and normal
shared libraries on other platforms. This property may be set to a list of files to be placed in
the Resources directory inside the framework folder. On non-Apple platforms these files may be
installed using the RESOURCE option to the install(TARGETS) command.
RULE_LAUNCH_COMPILE
Specify a launcher for compile rules.
See the global property of the same name for details. This overrides the global and directory
property for a target.
RULE_LAUNCH_CUSTOM
Specify a launcher for custom rules.
See the global property of the same name for details. This overrides the global and directory
property for a target.
RULE_LAUNCH_LINK
Specify a launcher for link rules.
See the global property of the same name for details. This overrides the global and directory
property for a target.
RUNTIME_OUTPUT_DIRECTORY
Output directory in which to build RUNTIME target files.
This property specifies the directory into which runtime target files should be built.
Multi-configuration generators (VS, Xcode) append a per-configuration subdirectory to the
specified directory. There are three kinds of target files that may be built: archive, library,
and runtime. Executables are always treated as runtime targets. Static libraries are always
treated as archive targets. Module libraries are always treated as library targets. For non-DLL
platforms shared libraries are treated as library targets. For DLL platforms the DLL part of a
shared library is treated as a runtime target and the corresponding import library is treated as
an archive target. All Windows-based systems including Cygwin are DLL platforms. This property is
initialized by the value of the variable CMAKE_RUNTIME_OUTPUT_DIRECTORY if it is set when a target
is created.
RUNTIME_OUTPUT_DIRECTORY_<CONFIG>
Per-configuration output directory for RUNTIME target files.
This is a per-configuration version of RUNTIME_OUTPUT_DIRECTORY, but multi-configuration
generators (VS, Xcode) do NOT append a per-configuration subdirectory to the specified directory.
This property is initialized by the value of the variable CMAKE_RUNTIME_OUTPUT_DIRECTORY_<CONFIG>
if it is set when a target is created.
RUNTIME_OUTPUT_NAME
Output name for RUNTIME target files.
This property specifies the base name for runtime target files. It overrides OUTPUT_NAME and
OUTPUT_NAME_<CONFIG> properties. There are three kinds of target files that may be built:
archive, library, and runtime. Executables are always treated as runtime targets. Static
libraries are always treated as archive targets. Module libraries are always treated as library
targets. For non-DLL platforms shared libraries are treated as library targets. For DLL platforms
the DLL part of a shared library is treated as a runtime target and the corresponding import
library is treated as an archive target. All Windows-based systems including Cygwin are DLL
platforms.
RUNTIME_OUTPUT_NAME_<CONFIG>
Per-configuration output name for RUNTIME target files.
This is the configuration-specific version of RUNTIME_OUTPUT_NAME.
SKIP_BUILD_RPATH
Should rpaths be used for the build tree.
SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic generation of an rpath allowing
the target to run from the build tree. This property is initialized by the value of the variable
CMAKE_SKIP_BUILD_RPATH if it is set when a target is created.
SOURCES
Source names specified for a target.
Read-only list of sources specified for a target. The names returned are suitable for passing to
the set_source_files_properties command.
SOVERSION
What version number is this target.
For shared libraries VERSION and SOVERSION can be used to specify the build version and API
version respectively. When building or installing appropriate symlinks are created if the platform
supports symlinks and the linker supports so-names. If only one of both is specified the missing
is assumed to have the same version number. SOVERSION is ignored if NO_SONAME property is set. For
shared libraries and executables on Windows the VERSION attribute is parsed to extract a
"major.minor" version number. These numbers are used as the image version of the binary.
STATIC_LIBRARY_FLAGS
Extra flags to use when linking static libraries.
Extra flags to use when linking a static library.
STATIC_LIBRARY_FLAGS_<CONFIG>
Per-configuration flags for creating a static library.
This is the configuration-specific version of STATIC_LIBRARY_FLAGS.
SUFFIX What comes after the target name.
A target property that can be set to override the suffix (such as ".so" or ".exe") on the name of
a library, module or executable.
TYPE The type of the target.
This read-only property can be used to test the type of the given target. It will be one of
STATIC_LIBRARY, MODULE_LIBRARY, SHARED_LIBRARY, EXECUTABLE or one of the internal target types.
VERSION
What version number is this target.
For shared libraries VERSION and SOVERSION can be used to specify the build version and API
version respectively. When building or installing appropriate symlinks are created if the platform
supports symlinks and the linker supports so-names. If only one of both is specified the missing
is assumed to have the same version number. For executables VERSION can be used to specify the
build version. When building or installing appropriate symlinks are created if the platform
supports symlinks. For shared libraries and executables on Windows the VERSION attribute is parsed
to extract a "major.minor" version number. These numbers are used as the image version of the
binary.
VISIBILITY_INLINES_HIDDEN
Whether to add a compile flag to hide symbols of inline functions
The VISIBILITY_INLINES_HIDDEN property determines whether a flag for hiding symbols for inline
functions. the value passed used in a visibility related compile option, such as -fvisibility=.
This property only has an affect for libraries and executables with exports. This property is
initialized by the value of the variable CMAKE_VISIBILITY_INLINES_HIDDEN if it is set when a
target is created.
VS_DOTNET_REFERENCES
Visual Studio managed project .NET references
Adds one or more semicolon-delimited .NET references to a generated Visual Studio project. For
example, "System;System.Windows.Forms".
VS_DOTNET_TARGET_FRAMEWORK_VERSION
Specify the .NET target framework version.
Used to specify the .NET target framework version for C++/CLI. For example, "v4.5".
VS_GLOBAL_<variable>
Visual Studio project-specific global variable.
Tell the Visual Studio generator to set the global variable '<variable>' to a given value in the
generated Visual Studio project. Ignored on other generators. Qt integration works better if
VS_GLOBAL_QtVersion is set to the version FindQt4.cmake found. For example, "4.7.3"
VS_GLOBAL_KEYWORD
Visual Studio project keyword.

may wish to override this value with "ManagedCProj", for example, in a Visual Studio managed C++
unit test project.
VS_GLOBAL_PROJECT_TYPES
Visual Studio project type(s).
Can be set to one or more UUIDs recognized by Visual Studio to indicate the type of project. This
value is copied verbatim into the generated project file. Example for a managed C++ unit testing
project:
{3AC096D0-A1C2-E12C-1390-A8335801FDAB};{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}
UUIDs are semicolon-delimited.
VS_GLOBAL_ROOTNAMESPACE
Visual Studio project root namespace.
Sets the "RootNamespace" attribute for a generated Visual Studio project. The attribute will be
generated only if this is set.
VS_KEYWORD

VS_SCC_LOCALPATH
Visual Studio Source Code Control Local Path.
Can be set to change the visual studio source code control local path property.
VS_SCC_PROJECTNAME
Visual Studio Source Code Control Project.
Can be set to change the visual studio source code control project name property.
VS_SCC_PROVIDER
Visual Studio Source Code Control Provider.
Can be set to change the visual studio source code control provider property.
VS_WINRT_EXTENSIONS
Visual Studio project C++/CX language extensions for Windows Runtime
Can be set to enable C++/CX language extensions.
VS_WINRT_REFERENCES
Visual Studio project Windows Runtime Metadata references
Adds one or more semicolon-delimited WinRT references to a generated Visual Studio project. For
example, "Windows;Windows.UI.Core".
WIN32_EXECUTABLE
Build an executable with a WinMain entry point on windows.
When this property is set to true the executable when linked on Windows will be created with a
WinMain() entry point instead of just main(). This makes it a GUI executable instead of a console
application. See the CMAKE_MFC_FLAG variable documentation to configure use of MFC for WinMain
executables. This property is initialized by the value of the variable CMAKE_WIN32_EXECUTABLE if
it is set when a target is created.
XCODE_ATTRIBUTE_<an-attribute>
Set Xcode target attributes directly.
Tell the Xcode generator to set '<an-attribute>' to a given value in the generated Xcode project.
Ignored on other generators.
PROPERTIES ON TESTS
ATTACHED_FILES
Attach a list of files to a dashboard submission.
Set this property to a list of files that will be encoded and submitted to the dashboard as an
addition to the test result.
ATTACHED_FILES_ON_FAIL
Attach a list of files to a dashboard submission if the test fails.
Same as ATTACHED_FILES, but these files will only be included if the test does not pass.
COST Set this to a floating point value. Tests in a test set will be run in descending order of cost.
This property describes the cost of a test. You can explicitly set this value; tests with higher
COST values will run first.
DEPENDS
Specifies that this test should only be run after the specified list of tests.
Set this to a list of tests that must finish before this test is run.
ENVIRONMENT
Specify environment variables that should be defined for running a test.
If set to a list of environment variables and values of the form MYVAR=value those environment
variables will be defined while running the test. The environment is restored to its previous
state after the test is done.
FAIL_REGULAR_EXPRESSION
If the output matches this regular expression the test will fail.
If set, if the output matches one of specified regular expressions, the test will fail.For
example: FAIL_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"
LABELS Specify a list of text labels associated with a test.
The list is reported in dashboard submissions.
MEASUREMENT
Specify a CDASH measurement and value to be reported for a test.
If set to a name then that name will be reported to CDASH as a named measurement with a value of
1. You may also specify a value by setting MEASUREMENT to "measurement=value".
PASS_REGULAR_EXPRESSION
The output must match this regular expression for the test to pass.
If set, the test output will be checked against the specified regular expressions and at least one
of the regular expressions has to match, otherwise the test will fail.
PROCESSORS
How many process slots this test requires
Denotes the number of processors that this test will require. This is typically used for MPI
tests, and should be used in conjunction with the ctest_test PARALLEL_LEVEL option.
REQUIRED_FILES
List of files required to run the test.
If set to a list of files, the test will not be run unless all of the files exist.
RESOURCE_LOCK
Specify a list of resources that are locked by this test.
If multiple tests specify the same resource lock, they are guaranteed not to run concurrently.
RUN_SERIAL
Do not run this test in parallel with any other test.
Use this option in conjunction with the ctest_test PARALLEL_LEVEL option to specify that this test
should not be run in parallel with any other tests.
TIMEOUT
How many seconds to allow for this test.
This property if set will limit a test to not take more than the specified number of seconds to
run. If it exceeds that the test process will be killed and ctest will move to the next test. This
setting takes precedence over CTEST_TESTING_TIMEOUT.
WILL_FAIL
If set to true, this will invert the pass/fail flag of the test.
This property can be used for tests that are expected to fail and return a non zero return code.
WORKING_DIRECTORY
The directory from which the test executable will be called.
If this is not set it is called from the directory the test executable is located in.
VARIABLES
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
ofCMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION when CPack runsVariables common to all CPack
generators
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_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
Version of cmake required to build project
From the point of view of backwards compatibility, this specifies what version of CMake should be
supported. By default this value is the version number of CMake that you are running. You can set
this to an older version of CMake to support deprecated commands of CMake in projects that were
written to use older versions of CMake. This can be set by the user or set at the beginning of a
CMakeLists file.
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 make 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 generator.
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 and COMPILE_OPTIONS target properties. In that case, it
outputs a backtrace 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 -U
CMAKE_ERROR_DEPRECATED
Whether to issue deprecation errors for macros and functions.
If TRUE, this can be used by macros and functions to issue fatal errors when deprecated macros or
functions are used. This variable is FALSE by default.
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_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_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_IGNORE_PATH
Path to be ignored by FIND_XXX() commands.
Specifies directories to be ignored by searches in FIND_XXX() commands. This is useful in
cross-compiled 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 that modules like FindX11
(and others) would normally search. 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. If
you want to ignore paths under prefixes (bin, include, lib, etc.), you'll need to specify them
explicitly. See also CMAKE_PREFIX_PATH, CMAKE_LIBRARY_PATH, CMAKE_INCLUDE_PATH,
CMAKE_PROGRAM_PATH.
CMAKE_INCLUDE_PATH
Path used for searching by FIND_FILE() and FIND_PATH().
Specifies a path which will be used both by FIND_FILE() and FIND_PATH(). Both commands will check
each of the contained directories for the existence of the file which is currently searched. By
default it is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_INCLUDE_PATH,
CMAKE_PREFIX_PATH.
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_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.
CMAKE_LIBRARY_PATH
Path used for searching by FIND_LIBRARY().
Specifies a path which will be used by FIND_LIBRARY(). FIND_LIBRARY() will check each of the
contained directories for the existence of the library which is currently searched. By default it
is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_LIBRARY_PATH,
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 to search for CMake modules.
Commands like include() and find_package() search for files in directories listed by this variable
before checking the default modules that come with CMake.
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_PREFIX_PATH
Path used for searching by FIND_XXX(), with appropriate suffixes added.
Specifies a path which will be used by the FIND_XXX() commands. It contains the "base"
directories, the FIND_XXX() commands append appropriate subdirectories to the base directories. So
FIND_PROGRAM() adds /bin to each of the directories in the path, FIND_LIBRARY() appends /lib to
each of the directories, and FIND_PATH() and FIND_FILE() append /include . By default it 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.
CMAKE_PROGRAM_PATH
Path used for searching by FIND_PROGRAM().
Specifies a path which will be used by FIND_PROGRAM(). FIND_PROGRAM() will check each of the
contained directories for the existence of the program which is currently searched. By default it
is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_PROGRAM_PATH,
CMAKE_PREFIX_PATH.
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_SYSTEM_IGNORE_PATH
Path to be ignored by FIND_XXX() commands.
Specifies directories to be ignored by searches in FIND_XXX() commands. This is useful in
cross-compiled 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 that modules like FindX11
(and others) would normally search. By default this contains a list of directories containing
incompatible binaries for the host system. See also CMAKE_SYSTEM_PREFIX_PATH,
CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_SYSTEM_INCLUDE_PATH, and CMAKE_SYSTEM_PROGRAM_PATH.
CMAKE_SYSTEM_INCLUDE_PATH
Path used for searching by FIND_FILE() and FIND_PATH().
Specifies a path which will be used both by FIND_FILE() and FIND_PATH(). Both commands will check
each of the contained directories for the existence of the file which is currently searched. By
default it 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
Path used for searching by FIND_LIBRARY().
Specifies a path which will be used by FIND_LIBRARY(). FIND_LIBRARY() will check each of the
contained directories for the existence of the library which is currently searched. By default it
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
Path used for searching by FIND_XXX(), with appropriate suffixes added.
Specifies a path which will be used by the FIND_XXX() commands. It contains the "base"
directories, the FIND_XXX() commands append appropriate subdirectories to the base directories. So
FIND_PROGRAM() adds /bin to each of the directories in the path, FIND_LIBRARY() appends /lib to
each of the directories, and FIND_PATH() and FIND_FILE() append /include . By default this
contains the standard directories for the current system and the CMAKE_INSTALL_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
Path used for searching by FIND_PROGRAM().
Specifies a path which will be used by FIND_PROGRAM(). FIND_PROGRAM() will check each of the
contained directories for the existence of the program which is currently searched. By default it
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 deprecation warnings for macros and functions.
If TRUE, this can be used by macros and functions to issue deprecation warnings. This variable is
FALSE by default.
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 Mac OS X.
Set to true on Mac OS X.
BORLAND
True if the Borland compiler is being used.
This is set to true if the Borland compiler is being used.

The same as CMAKE_SYSTEM but for the host system instead of the target system when cross
compiling.
CMAKE_HOST_SYSTEM_NAME
Name of the OS CMake is running on.
The same as CMAKE_SYSTEM_NAME but for the host system instead of the target system when cross
compiling.
CMAKE_HOST_SYSTEM_PROCESSOR
The name of the CPU CMake is running on.
The same as CMAKE_SYSTEM_PROCESSOR but for the host system instead of the target system when cross
compiling.

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_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_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 of system cmake is compiling for.
This variable is the composite of CMAKE_SYSTEM_NAME and CMAKE_SYSTEM_VERSION, like this
${CMAKE_SYSTEM_NAME}-${CMAKE_SYSTEM_VERSION}. If CMAKE_SYSTEM_VERSION is not set, then
CMAKE_SYSTEM is the same as CMAKE_SYSTEM_NAME.
CMAKE_SYSTEM_NAME
Name of the OS CMake is building for.
This is the name of the operating system on which CMake is targeting. On systems that have the
uname command, this variable is set to the output of uname -s. Linux, Windows, and Darwin for
Mac OS X are the values found on the big three operating systems.
CMAKE_SYSTEM_PROCESSOR
The name of the CPU CMake is building for.
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_SYSTEM_VERSION
OS version CMake is building for.
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.
CYGWIN True for Cygwin.
Set to true when using Cygwin.
ENV Access environment variables.
Use the syntax $ENV{VAR} to read environment variable VAR. See also the set() command to set
ENV{VAR}.

MSVC90 True when using Microsoft Visual C 9.0
Set to true when the compiler is version 9.0 of Microsoft Visual C.
MSVC_IDE
True when using the Microsoft Visual C IDE
Set to true when the target platform is the Microsoft Visual C IDE, as opposed to the command line
compiler.
MSVC_VERSION
The version of Microsoft Visual C/C++ being used if any.
Known version numbers are:
1200 = VS 6.0
1300 = VS 7.0
1310 = VS 7.1
1400 = VS 8.0
1500 = VS 9.0
1600 = VS 10.0
1700 = VS 11.0
1800 = VS 12.0
UNIX True for UNIX and UNIX like operating systems.
Set to true when the target system is UNIX or UNIX like (i.e. APPLE and CYGWIN).

XCODE_VERSION
Version of Xcode (Xcode generator only).
Under the Xcode generator, this is the version of Xcode as specified in
"Xcode.app/Contents/version.plist" (such as "3.1.2").
VARIABLES COMMON TO ALL CPACK GENERATORS
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_BINARY_<GENNAME>
CPack generated options for binary generators
The CPack.cmake module generates (when CPACK_GENERATOR is not set) a set of CMake options (see
CMake option command) which may then be used to select the CPack generator(s) to be used when
launching the package target.
CPACK_CMAKE_GENERATOR
What CMake generator should be used if the project is CMake project.
Defaults to the value of CMAKE_GENERATOR few users will want to change this setting.
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_CREATE_DESKTOP_LINKS
List of desktop links to create
CPACK_GENERATOR
List of CPack generators to use
If not specified, CPack will create a set of options CPACK_BINARY_<GENNAME> (e.g.,
CPACK_BINARY_NSIS) allowing the user to enable/disable individual generators. This variable may be
used on the command line as well as in:
cpack -D CPACK_GENERATOR="ZIP;TGZ" /path/to/build/tree
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_INSTALLED_DIRECTORIES
Extra directories to install
CPACK_INSTALL_CMAKE_PROJECTS
List of four values that specify what project to install.
The four values are: Build directory, Project Name, Project Component, Directory. If omitted,
CPack will build an installer that installers everything.
CPACK_INSTALL_COMMANDS
Extra commands to install components
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_MONOLITHIC_INSTALL
Disables the component-based installation mechanism.
When set the component specification is ignored and all installed items are put in a single
"MONOLITHIC" package. Some CPack generators do monolithic packaging by default and may be asked to
do component packaging by setting CPACK_<GENNAME>_COMPONENT_INSTALL to 1/TRUE.
CPACK_OUTPUT_CONFIG_FILE
The name of the CPack binary configuration file.
This file is the CPack configuration generated by the CPack module for binary installers. Defaults
to CPackConfig.cmake.
CPACK_PACKAGE_DESCRIPTION_FILE
A text file used to describe the project.
Used, for example, the introduction screen of a CPack-generated Windows installer to describe the
project.
CPACK_PACKAGE_DESCRIPTION_SUMMARY
Short description of the project (only a few words).
CPACK_PACKAGE_DIRECTORY
The directory in which CPack is doing its packaging.
If it is not set then this will default (internally) to the build dir. This variable may 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.
CPACK_PACKAGE_EXECUTABLES
Lists each of the executables and associated text label to be used to create Start Menu shortcuts.
For example, setting this to the list ccmake;CMake will create a shortcut named "CMake" that will
execute the installed executable ccmake. Not all CPack generators use it (at least NSIS and OSXX11
do).
CPACK_PACKAGE_FILE_NAME
The name of the package file to generate, not including the extension.
For example, cmake-2.6.1-Linux-i686. The default value is
${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}.
CPACK_PACKAGE_ICON
A branding image that will be displayed inside the installer (used by GUI installers).
CPACK_PACKAGE_INSTALL_DIRECTORY
Installation directory on the target system.
This may be used by some CPack generators like NSIS to create an installation directory e.g.,
"CMake 2.5" below the installation prefix. All installed element will be put inside this
directory.
CPACK_PACKAGE_INSTALL_REGISTRY_KEY
Registry key used when installing this project.
This is only used by installer for Windows. The default value is based on the installation
directory.
CPACK_PACKAGE_NAME
The name of the package (or application)
If not specified, defaults to the project name.
CPACK_PACKAGE_VENDOR
The name of the package vendor
(e.g., "Kitware").
CPACK_PACKAGE_VERSION
Package full version, used internally
By default, this is built from CPACK_PACKAGE_VERSION_MAJOR, CPACK_PACKAGE_VERSION_MINOR, and
CPACK_PACKAGE_VERSION_PATCH.
CPACK_PACKAGE_VERSION_MAJOR
Package major Version
CPACK_PACKAGE_VERSION_MINOR
Package minor Version
CPACK_PACKAGE_VERSION_PATCH
Package patch Version
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 command line by setting an alternative value.
e.g. 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_PROJECT_CONFIG_FILE
CPack-time project CPack configuration file.
This file included at cpack time, once per generator after CPack has set CPACK_GENERATOR to the
actual generator being used. It allows per-generator setting of CPACK_* variables at cpack time.
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.
CPACK_RESOURCE_FILE_README
ReadMe file to be embedded in the installer
It typically describes in some detail the purpose of the project during the installation. Not all
CPack generators uses this file.
CPACK_RESOURCE_FILE_WELCOME
Welcome file to be embedded in the installer.
It welcomes users to this installer. Typically used in the graphical installers on Windows and Mac
OS X.
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_SOURCE_GENERATOR
List of generators used for the source packages.
As with CPACK_GENERATOR, if this is not specified then CPack will create a set of options (e.g.,
CPACK_SOURCE_ZIP) allowing users to select which packages will be generated.
CPACK_SOURCE_IGNORE_FILES
Pattern of files in the source tree that won't be packaged when building a source package.
This is a list of regular expression patterns (that must be properly escaped), e.g.,
/CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*
CPACK_SOURCE_OUTPUT_CONFIG_FILE
The name of the CPack source configuration file.
This file is the CPack configuration generated by the CPack module for source installers. Defaults
to CPackSourceConfig.cmake.
CPACK_SOURCE_PACKAGE_FILE_NAME
The name of the source package
For example cmake-2.6.1.
CPACK_SOURCE_STRIP_FILES
List of files in the source tree that will be stripped.
Starting with CMake 2.6.0 CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
stripping of all files (a list of files evaluates to TRUE in CMake, so this change is compatible).
CPACK_STRIP_FILES
List of files to be stripped
Starting with CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which enables stripping of
all files (a list of files evaluates to TRUE in CMake, so this change is compatible).
CPACK_SYSTEM_NAME
System name, defaults to the value of ${CMAKE_SYSTEM_NAME}.
CPACK_TOPLEVEL_TAG
Directory for the installed files
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.
VARIABLES CONCERNING CPACK COMPONENTS
CPACK_<GENNAME>_COMPONENT_INSTALL
Enable/Disable component install for CPack generator <GENNAME>.
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.
CPACK_COMPONENTS_ALL
The list of component to install
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.
CPACK_COMPONENTS_GROUPING
Specify how components are grouped for multi-package component-aware CPack generators.
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:
- ONE_PER_GROUP (default): creates one package file per component group
- ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component
- IGNORE : creates one package per component, i.e. IGNORE component group
One can specify different grouping for different CPack generator by using a
CPACK_PROJECT_CONFIG_FILE.

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
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>_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>_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.

CMAKE_<LANG>_PLATFORM_ID
An internal variable subject to change.
This is used in determining the platform and is subject to change.
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_COMPILER_IS_GNU<LANG>
True if the compiler is GNU.
If the selected <LANG> compiler is the GNU compiler then this is TRUE, if not it is FALSE. Unlike
the other per-language variables, this uses the GNU syntax for identifying languages instead of
the CMake syntax. Recognized values of the <LANG> suffix are:
CC = C compiler
CXX = C++ compiler
G77 = Fortran compiler
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
Fortran flag for module output directory.
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.
CMAKE_INTERNAL_PLATFORM_ABI
An internal variable subject to change.
This is used in determining the compiler ABI and is subject to change.
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>.

If set CPack will generate a template for USER specified binary
spec file and stop with an error. For example launch CPack like this
cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM
The user may then use this file in order to hand-craft is own
binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE.

The refered script file(s) will be read and directly
put after the %post or %postun section
If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
each component can be overridden with
CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE and
CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE
One may verify which scriptlet has been included with
rpm -qp --scripts package.rpm

Mandatory : NO
Default : -
May be used to add any %define lines to the generated spec file.
CPACK_RPM_USER_BINARY_SPECFILE
A user provided spec file
Mandatory : NO
Default : -
May be set by the user in order to specify a USER binary spec file
to be used by CPackRPM instead of generating the file.
The specified file will be processed by configure_file( @ONLY).
One can provide a component specific file by setting
CPACK_RPM_<componentName>_USER_BINARY_SPECFILE.
CPACK_RPM_USER_FILELIST
CPACK_RPM_<COMPONENT>_USER_FILELIST
Mandatory : NO
Default : -
May be used to explicitly specify %(<directive>) file line
in the spec file. Like %config(noreplace) or any other directive
that be found in the %files section. Since CPackRPM is generating
the list of files (and directories) the user specified files of
the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the generated list.
VARIABLES SPECIFIC TO CPACK WIX GENERATOR
CPACK_WIX_CULTURES
Language(s) of the installer
Languages are compiled into the WixUI extension library. To use them, simply provide the name of
the culture. If you specify more than one culture identifier in a comma or semicolon delimited
list, the first one that is found will be used. You can find a list of supported languages at:
http://wix.sourceforge.net/manual-wix3/WixUI_localization.htm
CPACK_WIX_LICENSE_RTF
RTF License File
If CPACK_RESOURCE_FILE_LICENSE has an .rtf extension it is used as-is.
If CPACK_RESOURCE_FILE_LICENSE has an .txt extension it is implicitly converted to RTF by the WiX
Generator.
With CPACK_WIX_LICENSE_RTF you can override the license file used by the WiX Generator in case
CPACK_RESOURCE_FILE_LICENSE is in an unsupported format or the .txt -> .rtf conversion does not
work as expected.
CPACK_WIX_PRODUCT_GUID

The installer will abort if it detects a pre-existing installation that uses the same GUID.
The GUID shall use the syntax described for CPACK_WIX_UPGRADE_GUID.
CPACK_WIX_PRODUCT_ICON
The Icon shown next to the program name in Add/Remove programs
If set, this icon is used in place of the default icon.
CPACK_WIX_PROGRAM_MENU_FOLDER
Start menu folder name for launcher
If this variable is not set, it will be initialized with CPACK_PACKAGE_NAME
CPACK_WIX_TEMPLATE
Template file for WiX generation
If this variable is set, the specified template will be used to generate the WiX wxs file. This
should be used if further customization of the output is required.
If this variable is not set, the default MSI template included with CMake will be used.
CPACK_WIX_UI_BANNER
The bitmap will appear at the top of all installer pages other than the welcome and completion
dialogs
If set, this image will replace the default banner image.
This image must be 493 by 58 pixels.
CPACK_WIX_UI_DIALOG
Background bitmap used on the welcome and completion dialogs
If this variable is set, the installer will replace the default dialog image.
This image must be 493 by 312 pixels.
CPACK_WIX_UPGRADE_GUID
Upgrade GUID (Product/@UpgradeCode)
Will be automatically generated unless explicitly provided.
It should be explicitly set to a constant generated gloabally unique identifier (GUID) to allow
your installers to replace existing installations that use the same GUID.
You may for example explicitly set this variable in your CMakeLists.txt to the value that has been
generated per default. You should not use GUIDs that you did not generate yourself or which may
belong to other projects.
A GUID shall have the following fixed length syntax: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
(each X represents an uppercase hexadecimal digit)
VARIABLES THAT CONTROL THE BUILD
CMAKE_<CONFIG>_POSTFIX

target property for additional information.
CMAKE_BUILD_WITH_INSTALL_RPATH
Use the install path for the RPATH
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 built with the install
path for the RPATH and does not need to be relinked when installed.
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.

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
Automatically add the current source- and build directories to the include path.
If this variable is enabled, CMake automatically adds in each directory
${CMAKE_CURRENT_SOURCE_DIR} and ${CMAKE_CURRENT_BINARY_DIR} to the include path for this
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_INCLUDE_CURRENT_DIR_IN_INTERFACE
Automatically add the current source- and build directories to the INTERFACE_INCLUDE_DIRECTORIES.
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.By default
CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE is OFF.
CMAKE_INSTALL_NAME_DIR
Mac OS X directory name for installed targets.

that target property for more information.
CMAKE_INSTALL_RPATH
The rpath to use for installed targets.
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.

This variable is used to initialize the LIBRARY_OUTPUT_DIRECTORY property on all the targets. See
that target property for additional information.
CMAKE_LIBRARY_PATH_FLAG
The flag to be used to add a library search path to a compiler.
The flag will be used to specify a library directory to the compiler. On most compilers this is
"-L".
CMAKE_LINK_DEF_FILE_FLAG
Linker flag to be used to specify a .def file for dll creation.
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
Default value for MACOSX_BUNDLE of targets.
This variable is used to initialize the MACOSX_BUNDLE property on all the targets. See that
target property for additional information.
CMAKE_MODULE_LINKER_FLAGS
Linker flags to be used to create modules.
These flags will be used by the linker when creating a module.
CMAKE_MODULE_LINKER_FLAGS_<CONFIG>
Flags to be used when linking a module.
Same as CMAKE_C_FLAGS_* but used by the linker when creating modules.
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_PDB_OUTPUT_DIRECTORY
Where to put all the MS debug symbol files from linker.
This variable is used to initialize the PDB_OUTPUT_DIRECTORY property on all the targets. See
that target property for additional information.
CMAKE_POSITION_INDEPENDENT_CODE
Default value for POSITION_INDEPENDENT_CODE of targets.
This variable is used to initialize the POSITION_INDEPENDENT_CODE property on all the targets.
See that target property for additional information.

that target property for additional information.
CMAKE_SHARED_LINKER_FLAGS
Linker flags to be used to create shared libraries.
These flags will be used by the linker when creating a shared library.
CMAKE_SHARED_LINKER_FLAGS_<CONFIG>
Flags to be used when linking a shared library.
Same as CMAKE_C_FLAGS_* but used by the linker when creating shared libraries.
CMAKE_SKIP_BUILD_RPATH
Do not include RPATHs in the build 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 built with no RPATH.
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
Linker flags to be used to create static libraries.
These flags will be used by the linker when creating a static library.
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_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
Use relative paths (May not work!).
If this is set to TRUE, then CMake will use relative paths between the source and binary tree.
This option does not work for more complicated projects, and relative paths are used when
possible. In general, it is not possible to move CMake generated makefiles to a different
location regardless of the value of this variable.
CMAKE_VISIBILITY_INLINES_HIDDEN
Default value for VISIBILITY_INLINES_HIDDEN of targets.
This variable is used to initialize the VISIBILITY_INLINES_HIDDEN property on all the targets.
See that target property for additional information.
CMAKE_WIN32_EXECUTABLE
Default value for WIN32_EXECUTABLE of targets.
This variable is used to initialize the WIN32_EXECUTABLE property on all the targets. See that
target property for additional information.
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.
VARIABLES THAT PROVIDE INFORMATION
CMAKE_AR
Name of archiving tool for static libraries.
This specifies the name of the program that creates archive or static libraries.
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_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.
CMAKE_BUILD_TOOL
Tool used for the actual build process.
This variable is set to the program that will be needed to build the output of CMake. If the
generator selected was Visual Studio 6, the CMAKE_BUILD_TOOL will be set to msdev, for Unix
Makefiles it will be set to make or gmake, and for Visual Studio 7 it set to devenv. For NMake
Makefiles the value is nmake. This can be useful for adding special flags and commands based on
the final build environment.
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 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
$(OutDir) = 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 executable.
This is the full path to the CMake executable cmake 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_CTEST_COMMAND
Full path to ctest command installed with cmake.
This is the full path to the CTest executable ctest which is useful from custom commands that want
to use the cmake -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.
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.
See also CMAKE_CURRENT_LIST_FILE.
CMAKE_CURRENT_LIST_FILE
Full path to the listfile currently being processed.
As CMake processes the listfiles in your project this variable will always be set to the one
currently being processed. The value has dynamic scope. When CMake starts processing commands in
a source file it sets this variable to the location of the file. 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 file invoking the bottom-most entry on the call stack, not the file
containing the macro or function definition.
See also CMAKE_PARENT_LIST_FILE.
CMAKE_CURRENT_LIST_LINE
The line number of the current file being processed.
This is the line number of the file currently being processed by cmake.
CMAKE_CURRENT_SOURCE_DIR
The path to the source directory currently being processed.
This the full path to the source directory that is currently being processed by cmake.
CMAKE_DL_LIBS
Name of library containing dlopen and dlcose.
The name of the library that has dlopen and dlclose in it, usually -ldl on most UNIX machines.
CMAKE_EDIT_COMMAND
Full path to cmake-gui or ccmake.
This is the full path to the CMake executable that can graphically edit the cache. For example,
cmake-gui, ccmake, or cmake -i.
CMAKE_EXECUTABLE_SUFFIX
The suffix for executables on this platform.
The suffix to use for the end of an executable filename if any, .exe on Windows.
CMAKE_EXECUTABLE_SUFFIX_<LANG> overrides this for language <LANG>.
CMAKE_EXTRA_GENERATOR
The extra generator used to build the project.
When using the Eclipse, CodeBlocks or KDevelop generators, CMake generates Makefiles
(CMAKE_GENERATOR) and additionally project files for the respective IDE. This IDE project file
generator is stored in CMAKE_EXTRA_GENERATOR (e.g. "Eclipse CDT4").
CMAKE_EXTRA_SHARED_LIBRARY_SUFFIXES
Additional suffixes for shared libraries.

Native build system toolset name specified by user.
Some CMake generators support a toolset name to be given to the native build system to choose a
compiler. If the user specifies a toolset name (e.g. via the cmake -T option) the value will be
available in this variable.
CMAKE_HOME_DIRECTORY
Path to top of source tree.
This is the path to the top level of the source tree.
CMAKE_IMPORT_LIBRARY_PREFIX

The prefix to use for the name of a loadable module on this platform.
CMAKE_SHARED_MODULE_PREFIX_<LANG> overrides this for language <LANG>.
CMAKE_SHARED_MODULE_SUFFIX
The suffix for shared libraries that you link to.
The suffix to use for the end of a loadable module filename on this platform
CMAKE_SHARED_MODULE_SUFFIX_<LANG> overrides this for language <LANG>.
CMAKE_SIZEOF_VOID_P
Size of a void pointer.
This is set to the size of a pointer on the machine, and is determined by a try compile. If a 64
bit size is found, then the library search path is modified to look for 64 bit libraries first.
CMAKE_SKIP_RPATH
If true, do not add run time path information.
If this is set to TRUE, then the rpath information is not added to compiled executables. The
default is to add rpath information if the platform supports it. This allows for easy running
from the build tree. To omit RPATH in the install step, but not the build step, use
CMAKE_SKIP_INSTALL_RPATH instead.
CMAKE_SOURCE_DIR
The path to the top level of the source tree.
This is the full path to the top level of the current CMake source tree. For an in-source build,
this would be the same as CMAKE_BINARY_DIR.
CMAKE_STANDARD_LIBRARIES
Libraries linked into every executable and shared library.
This is the list of libraries that are linked into all executables and libraries.
CMAKE_STATIC_LIBRARY_PREFIX
The prefix for static libraries that you link to.
The prefix to use for the name of a static library, lib on UNIX.
CMAKE_STATIC_LIBRARY_PREFIX_<LANG> overrides this for language <LANG>.
CMAKE_STATIC_LIBRARY_SUFFIX
The suffix for static libraries that you link to.
The suffix to use for the end of a static library filename, .lib on Windows.
CMAKE_STATIC_LIBRARY_SUFFIX_<LANG> overrides this for language <LANG>.
CMAKE_TWEAK_VERSION
The tweak version of cmake (i.e. the 1 in X.X.X.1).
This specifies the tweak version of the CMake executable being run. Releases use tweak < 20000000
and development versions use the date format CCYYMMDD for the tweak level.
CMAKE_VERBOSE_MAKEFILE
Create verbose makefiles if on.
This variable defaults to false. You can set this variable to true to make CMake produce verbose
makefiles that show each command line as it is used.
CMAKE_VERSION
The full version of cmake in major.minor.patch[.tweak[-id]] format.
This specifies the full version of the CMake executable being run. This variable is defined by
versions 2.6.3 and higher. See variables CMAKE_MAJOR_VERSION, CMAKE_MINOR_VERSION,
CMAKE_PATCH_VERSION, and CMAKE_TWEAK_VERSION for individual version components. The [-id]
component appears in non-release versions and may be arbitrary text.
CMAKE_VS_PLATFORM_TOOLSET
Visual Studio Platform Toolset name.
VS 10 and above use MSBuild under the hood and support multiple compiler toolchains. CMake may
specify a toolset explicitly, such as "v110" for VS 11 or "Windows7.1SDK" for 64-bit support in VS
10 Express. CMake provides the name of the chosen toolset in this variable.
CMAKE_XCODE_PLATFORM_TOOLSET
Xcode compiler selection.
Xcode supports selection of a compiler from one of the installed toolsets. CMake provides the
name of the chosen toolset in this variable, if any is explicitly selected (e.g. via the cmake -T
option).
PROJECT_BINARY_DIR
Full path to build directory for project.
This is the binary directory of the most recent PROJECT command.
PROJECT_NAME
Name of the project given to the project command.
This is the name given to the most recent PROJECT command.
PROJECT_SOURCE_DIR
Top level source directory for the current project.
This is the source directory of the most recent PROJECT command.
[Project name]_BINARY_DIR
Top level binary directory for the named project.
A variable is created with the name used in the PROJECT command, and is the binary directory for
the project. This can be useful when SUBDIR is used to connect several projects.
[Project name]_SOURCE_DIR
Top level source directory for the named project.
A variable is created with the name used in the PROJECT command, and is the source directory for
the project. This can be useful when add_subdirectory is used to connect several projects.
