DESCRIPTION
The cmake executable is the command-line interface of the cross-platform buildsystem
generator CMake. The above Synopsis lists various actions the tool can perform as
described in sections below.
To build a software project with CMake, Generate a Project Buildsystem. Optionally use
cmake to Build a Project, Install a Project or just run the corresponding build tool (e.g.
make) directly. cmake can also be used to View Help.
The other actions are meant for use by software developers writing scripts in the CMake
language to support their builds.
For graphical user interfaces that may be used in place of cmake, see ccmake and
cmake-gui. For command-line interfaces to the CMake testing and packaging facilities, see
ctest and cpack.
For more information on CMake at large, see also the links at the end of this manual.
INTRODUCTION TO CMAKE BUILDSYSTEMS
A buildsystem describes how to build a project's executables and libraries from its source
code using a build tool to automate the process. For example, a buildsystem may be a
Makefile for use with a command-line make tool or a project file for an Integrated
Development Environment (IDE). In order to avoid maintaining multiple such buildsystems,
a project may specify its buildsystem abstractly using files written in the CMake
language. From these files CMake generates a preferred buildsystem locally for each user
through a backend called a generator.
To generate a buildsystem with CMake, the following must be selected:
Source Tree
The top-level directory containing source files provided by the project. The
project specifies its buildsystem using files as described in the cmake-language(7)
manual, starting with a top-level file named CMakeLists.txt. These files specify
build targets and their dependencies as described in the cmake-buildsystem(7)
manual.
Build Tree
The top-level directory in which buildsystem files and build output artifacts (e.g.
executables and libraries) are to be stored. CMake will write a CMakeCache.txt
file to identify the directory as a build tree and store persistent information
such as buildsystem configuration options.
To maintain a pristine source tree, perform an out-of-source build by using a
separate dedicated build tree. An in-source build in which the build tree is
placed in the same directory as the source tree is also supported, but discouraged.
Generator
This chooses the kind of buildsystem to generate. See the cmake-generators(7)
manual for documentation of all generators. Run cmake --help to see a list of
generators available locally. Optionally use the -G option below to specify a
generator, or simply accept the default CMake chooses for the current platform.
When using one of the Command-Line Build Tool Generators CMake expects that the
environment needed by the compiler toolchain is already configured in the shell.
When using one of the IDE Build Tool Generators, no particular environment is
needed.
GENERATE A PROJECT BUILDSYSTEM
Run CMake with one of the following command signatures to specify the source and build
trees and generate a buildsystem:
cmake [<options>] <path-to-source>
Uses the current working directory as the build tree, and <path-to-source> as the
source tree. The specified path may be absolute or relative to the current working
directory. The source tree must contain a CMakeLists.txt file and must not contain
a CMakeCache.txt file because the latter identifies an existing build tree. For
example:
$ mkdir build ; cd build
$ cmake ../src
cmake [<options>] <path-to-existing-build>
Uses <path-to-existing-build> as the build tree, and loads the path to the source
tree from its CMakeCache.txt file, which must have already been generated by a
previous run of CMake. The specified path may be absolute or relative to the
current working directory. For example:
$ cd build
$ cmake .
cmake [<options>] -S <path-to-source> -B <path-to-build>
Uses <path-to-build> as the build tree and <path-to-source> as the source tree.
The specified paths may be absolute or relative to the current working directory.
The source tree must contain a CMakeLists.txt file. The build tree will be created
automatically if it does not already exist. For example:
$ cmake -S src -B build
In all cases the <options> may be zero or more of the Options below.
After generating a buildsystem one may use the corresponding native build tool to build
the project. For example, after using the Unix Makefiles generator one may run make
directly:
$ make
$ make install
Alternatively, one may use cmake to Build a Project by automatically choosing and invoking
the appropriate native build tool.
Options
-S <path-to-source>
Path to root directory of the CMake project to build.
-B <path-to-build>
Path to directory which CMake will use as the root of build directory.
If the directory doesn't already exist CMake will make it.
-C <initial-cache>
Pre-load a script to populate the cache.
When CMake is first run in an empty build tree, it creates a CMakeCache.txt file
and populates it with customizable settings for the project. This option may be
used to specify a file from which to load cache entries before the first pass
through the project's CMake listfiles. The loaded entries take priority over the
project's default values. The given file should be a CMake script containing set()
commands that use the CACHE option, not a cache-format file.
References to CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR within the script evaluate to
the top-level source and build tree.
-D <var>:<type>=<value>, -D <var>=<value>
Create or update a CMake CACHE entry.
When CMake is first run in an empty build tree, it creates a CMakeCache.txt file
and populates it with customizable settings for the project. This option may be
used to specify a setting that takes priority over the project's default value.
The option may be repeated for as many CACHE entries as desired.
If the :<type> portion is given it must be one of the types specified by the set()
command documentation for its CACHE signature. If the :<type> portion is omitted
the entry will be created with no type if it does not exist with a type already.
If a command in the project sets the type to PATH or FILEPATH then the <value> will
be converted to an absolute path.
This option may also be given as a single argument: -D<var>:<type>=<value> or
-D<var>=<value>.
-U <globbing_expr>
Remove matching entries from CMake CACHE.
This option may be used to remove one or more variables from the CMakeCache.txt
file, globbing expressions using * and ? are supported. The option may be repeated
for as many CACHE entries as desired.
Use with care, you can make your CMakeCache.txt non-working.
-G <generator-name>
Specify a build system generator.
CMake may support multiple native build systems on certain platforms. A generator
is responsible for generating a particular build system. Possible generator names
are specified in the cmake-generators(7) manual.
If not specified, CMake checks the CMAKE_GENERATOR environment variable and
otherwise falls back to a builtin default selection.
-T <toolset-spec>
Toolset specification for the generator, if supported.
Some CMake generators support a toolset specification to tell the native build
system how to choose a compiler. See the CMAKE_GENERATOR_TOOLSET variable for
details.
-A <platform-name>
Specify platform name if supported by generator.
Some CMake generators support a platform name to be given to the native build
system to choose a compiler or SDK. See the CMAKE_GENERATOR_PLATFORM variable for
details.
--toolchain <path-to-file>
Specify the cross compiling toolchain file, equivalent to setting
CMAKE_TOOLCHAIN_FILE variable.
--install-prefix <directory>
Specify the installation directory, used by the CMAKE_INSTALL_PREFIX variable. Must
be an absolute path.
-Wno-dev
Suppress developer warnings.
Suppress warnings that are meant for the author of the CMakeLists.txt files. By
default this will also turn off deprecation warnings.
-Wdev Enable developer warnings.
Enable warnings that are meant for the author of the CMakeLists.txt files. By
default this will also turn on deprecation warnings.
-Werror=dev
Make developer warnings errors.
Make warnings that are meant for the author of the CMakeLists.txt files errors. By
default this will also turn on deprecated warnings as errors.
-Wno-error=dev
Make developer warnings not errors.
Make warnings that are meant for the author of the CMakeLists.txt files not errors.
By default this will also turn off deprecated warnings as errors.
-Wdeprecated
Enable deprecated functionality warnings.
Enable warnings for usage of deprecated functionality, that are meant for the
author of the CMakeLists.txt files.
-Wno-deprecated
Suppress deprecated functionality warnings.
Suppress warnings for usage of deprecated functionality, that are meant for the
author of the CMakeLists.txt files.
-Werror=deprecated
Make deprecated macro and function warnings errors.
Make warnings for usage of deprecated macros and functions, that are meant for the
author of the CMakeLists.txt files, errors.
-Wno-error=deprecated
Make deprecated macro and function warnings not errors.
Make warnings for usage of deprecated macros and functions, that are meant for the
author of the CMakeLists.txt files, not errors.
-L[A][H]
List non-advanced cached variables.
List CACHE variables will run CMake and list all the variables from the CMake CACHE
that are not marked as INTERNAL or ADVANCED. This will effectively display current
CMake settings, which can then be changed with -D option. Changing some of the
variables may result in more variables being created. If A is specified, then it
will display also advanced variables. If H is specified, it will also display help
for each variable.
-N View mode only.
Only load the cache. Do not actually run configure and generate steps.
--graphviz=[file]
Generate graphviz of dependencies, see CMakeGraphVizOptions for more.
Generate a graphviz input file that will contain all the library and executable
dependencies in the project. See the documentation for CMakeGraphVizOptions for
more details.
--system-information [file]
Dump information about this system.
Dump a wide range of information about the current system. If run from the top of
a binary tree for a CMake project it will dump additional information such as the
cache, log files etc.
--log-level=<ERROR|WARNING|NOTICE|STATUS|VERBOSE|DEBUG|TRACE>
Set the log level.
The message() command will only output messages of the specified log level or
higher. The default log level is STATUS.
To make a log level persist between CMake runs, set CMAKE_MESSAGE_LOG_LEVEL as a
cache variable instead. If both the command line option and the variable are
given, the command line option takes precedence.
For backward compatibility reasons, --loglevel is also accepted as a synonym for
this option.
--log-context
Enable the message() command outputting context attached to each message.
This option turns on showing context for the current CMake run only. To make
showing the context persistent for all subsequent CMake runs, set
CMAKE_MESSAGE_CONTEXT_SHOW as a cache variable instead. When this command line
option is given, CMAKE_MESSAGE_CONTEXT_SHOW is ignored.
--debug-trycompile
Do not delete the try_compile() build tree. Only useful on one try_compile() at a
time.
Do not delete the files and directories created for try_compile() calls. This is
useful in debugging failed try_compiles. It may however change the results of the
try-compiles as old junk from a previous try-compile may cause a different test to
either pass or fail incorrectly. This option is best used for one try-compile at a
time, and only when debugging.
--debug-output
Put cmake in a debug mode.
Print extra information during the cmake run like stack traces with
message(SEND_ERROR) calls.
--debug-find
Put cmake find commands in a debug mode.
Print extra find call information during the cmake run to standard error. Output is
designed for human consumption and not for parsing. See also the
CMAKE_FIND_DEBUG_MODE variable for debugging a more local part of the project.
--trace
Put cmake in trace mode.
Print a trace of all calls made and from where.
--trace-expand
Put cmake in trace mode.
Like --trace, but with variables expanded.
--trace-format=<format>
Put cmake in trace mode and sets the trace output format.
<format> can be one of the following values.
human Prints each trace line in a human-readable format. This is the default
format.
json-v1
Prints each line as a separate JSON document. Each document is separated
by a newline ( \n ). It is guaranteed that no newline characters will be
present inside a JSON document.
JSON trace format:
{
"file": "/full/path/to/the/CMake/file.txt",
"line": 0,
"cmd": "add_executable",
"args": ["foo", "bar"],
"time": 1579512535.9687231,
"frame": 2
}
The members are:
file The full path to the CMake source file where the function was
called.
line The line in file of the function call.
defer Optional member that is present when the function call was
deferred by cmake_language(DEFER). If present, its value is a
string containing the deferred call <id>.
cmd The name of the function that was called.
args A string list of all function parameters.
time Timestamp (seconds since epoch) of the function call.
frame Stack frame depth of the function that was called.
Additionally, the first JSON document outputted contains the version key
for the current major and minor version of the
JSON trace format:
{
"version": {
"major": 1,
"minor": 1
}
}
The members are:
version
Indicates the version of the JSON format. The version has a major
and minor components following semantic version conventions.
--trace-source=<file>
Put cmake in trace mode, but output only lines of a specified file.
Multiple options are allowed.
--trace-redirect=<file>
Put cmake in trace mode and redirect trace output to a file instead of stderr.
--warn-uninitialized
Warn about uninitialized values.
Print a warning when an uninitialized variable is used.
--warn-unused-vars
Does nothing. In CMake versions 3.2 and below this enabled warnings about unused
variables. In CMake versions 3.3 through 3.18 the option was broken. In CMake
3.19 and above the option has been removed.
--no-warn-unused-cli
Don't warn about command line options.
Don't find variables that are declared on the command line, but not used.
--check-system-vars
Find problems with variable usage in system files.
Normally, unused and uninitialized variables are searched for only in
CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR. This flag tells CMake to warn about other
files as well.
--profiling-output=<path>
Used in conjunction with --profiling-format to output to a given path.
--profiling-format=<file>
Enable the output of profiling data of CMake script in the given format.
This can aid performance analysis of CMake scripts executed. Third party
applications should be used to process the output into human readable format.
Currently supported values are: google-trace Outputs in Google Trace Format, which
can be parsed by the about:tracing tab of Google Chrome or using a plugin for a
tool like Trace Compass.
--preset <preset>, --preset=<preset>
Reads a preset from <path-to-source>/CMakePresets.json and
<path-to-source>/CMakeUserPresets.json. The preset may specify the generator and
the build directory, and a list of variables and other arguments to pass to CMake.
The current working directory must contain CMake preset files. The CMake GUI can
also recognize CMakePresets.json and CMakeUserPresets.json files. For full details
on these files, see cmake-presets(7).
The presets are read before all other command line options. The options specified
by the preset (variables, generator, etc.) can all be overridden by manually
specifying them on the command line. For example, if the preset sets a variable
called MYVAR to 1, but the user sets it to 2 with a -D argument, the value 2 is
preferred.
--list-presets, --list-presets=<[configure | build | test | all]>
Lists the available presets. If no option is specified only configure presets will
be listed. The current working directory must contain CMake preset files.
BUILD A PROJECT
CMake provides a command-line signature to build an already-generated project binary tree:
cmake --build <dir> [<options>] [-- <build-tool-options>]
cmake --build --preset <preset> [<options>] [-- <build-tool-options>]
This abstracts a native build tool's command-line interface with the following options:
--build <dir>
Project binary directory to be built. This is required (unless a preset is
specified) and must be first.
--preset <preset>, --preset=<preset>
Use a build preset to specify build options. The project binary directory is
inferred from the configurePreset key. The current working directory must contain
CMake preset files. See preset for more details.
--list-presets
Lists the available build presets. The current working directory must contain CMake
preset files.
--parallel [<jobs>], -j [<jobs>]
The maximum number of concurrent processes to use when building. If <jobs> is
omitted the native build tool's default number is used.
The CMAKE_BUILD_PARALLEL_LEVEL environment variable, if set, specifies a default
parallel level when this option is not given.
Some native build tools always build in parallel. The use of <jobs> value of 1 can
be used to limit to a single job.
--target <tgt>..., -t <tgt>...
Build <tgt> instead of the default target. Multiple targets may be given,
separated by spaces.
--config <cfg>
For multi-configuration tools, choose configuration <cfg>.
--clean-first
Build target clean first, then build. (To clean only, use --target clean.)
--use-stderr
Ignored. Behavior is default in CMake >= 3.0.
--verbose, -v
Enable verbose output - if supported - including the build commands to be executed.
This option can be omitted if VERBOSE environment variable or
CMAKE_VERBOSE_MAKEFILE cached variable is set.
-- Pass remaining options to the native tool.
Run cmake --build with no options for quick help.
INSTALL A PROJECT
CMake provides a command-line signature to install an already-generated project binary
tree:
cmake --install <dir> [<options>]
This may be used after building a project to run installation without using the generated
build system or the native build tool. The options are:
--install <dir>
Project binary directory to install. This is required and must be first.
--config <cfg>
For multi-configuration generators, choose configuration <cfg>.
--component <comp>
Component-based install. Only install component <comp>.
--default-directory-permissions <permissions>
Default directory install permissions. Permissions in format <u=rwx,g=rx,o=rx>.
--prefix <prefix>
Override the installation prefix, CMAKE_INSTALL_PREFIX.
--strip
Strip before installing.
-v, --verbose
Enable verbose output.
This option can be omitted if VERBOSE environment variable is set.
Run cmake --install with no options for quick help.
OPEN A PROJECT
cmake --open <dir>
Open the generated project in the associated application. This is only supported by some
generators.
RUN A SCRIPT
cmake [{-D <var>=<value>}...] -P <cmake-script-file> [-- <unparsed-options>...]
Process the given cmake file as a script written in the CMake language. No configure or
generate step is performed and the cache is not modified. If variables are defined using
-D, this must be done before the -P argument.
Any options after -- are not parsed by CMake, but they are still included in the set of
CMAKE_ARGV<n> variables passed to the script (including the -- itself).
RUN A COMMAND-LINE TOOL
CMake provides builtin command-line tools through the signature
cmake -E <command> [<options>]
Run cmake -E or cmake -E help for a summary of commands. Available commands are:
capabilities
Report cmake capabilities in JSON format. The output is a JSON object with the
following keys:
version
A JSON object with version information. Keys are:
string The full version string as displayed by cmake --version.
major The major version number in integer form.
minor The minor version number in integer form.
patch The patch level in integer form.
suffix The cmake version suffix string.
isDirty
A bool that is set if the cmake build is from a dirty tree.
generators
A list available generators. Each generator is a JSON object with the
following keys:
name A string containing the name of the generator.
toolsetSupport
true if the generator supports toolsets and false otherwise.
platformSupport
true if the generator supports platforms and false otherwise.
supportedPlatforms
New in version 3.21.
Optional member that may be present when the generator supports
platform specification via CMAKE_GENERATOR_PLATFORM (-A ...). The
value is a list of platforms known to be supported.
extraGenerators
A list of strings with all the extra generators compatible with the
generator.
fileApi
Optional member that is present when the cmake-file-api(7) is available.
The value is a JSON object with one member:
requests
A JSON array containing zero or more supported file-api requests.
Each request is a JSON object with members:
kind Specifies one of the supported file-api object kinds.
version
A JSON array whose elements are each a JSON object containing
major and minor members specifying non-negative integer
version components.
serverMode
true if cmake supports server-mode and false otherwise. Always false since
CMake 3.20.
cat <files>...
Concatenate files and print on the standard output.
chdir <dir> <cmd> [<arg>...]
Change the current working directory and run a command.
compare_files [--ignore-eol] <file1> <file2>
Check if <file1> is same as <file2>. If files are the same, then returns 0, if not
it returns 1. In case of invalid arguments, it returns 2. The --ignore-eol option
implies line-wise comparison and ignores LF/CRLF differences.
copy <file>... <destination>
Copy files to <destination> (either file or directory). If multiple files are
specified, the <destination> must be directory and it must exist. Wildcards are not
supported. copy does follow symlinks. That means it does not copy symlinks, but
the files or directories it point to.
copy_directory <dir>... <destination>
Copy content of <dir>... directories to <destination> directory. If <destination>
directory does not exist it will be created. copy_directory does follow symlinks.
copy_if_different <file>... <destination>
Copy files to <destination> (either file or directory) if they have changed. If
multiple files are specified, the <destination> must be directory and it must
exist. copy_if_different does follow symlinks.
create_symlink <old> <new>
Create a symbolic link <new> naming <old>.
NOTE:
Path to where <new> symbolic link will be created has to exist beforehand.
create_hardlink <old> <new>
Create a hard link <new> naming <old>.
NOTE:
Path to where <new> hard link will be created has to exist beforehand. <old>
has to exist beforehand.
echo [<string>...]
Displays arguments as text.
echo_append [<string>...]
Displays arguments as text but no new line.
env [--unset=NAME]... [NAME=VALUE]... COMMAND [ARG]...
Run command in a modified environment.
environment
Display the current environment variables.

remove [-f] <file>...
Deprecated since version 3.17.
Remove the file(s). The planned behavior was that if any of the listed files
already do not exist, the command returns a non-zero exit code, but no message is
logged. The -f option changes the behavior to return a zero exit code (i.e.
success) in such situations instead. remove does not follow symlinks. That means
it remove only symlinks and not files it point to.
The implementation was buggy and always returned 0. It cannot be fixed without
breaking backwards compatibility. Use rm instead.
remove_directory <dir>...
Deprecated since version 3.17.
Remove <dir> directories and their contents. If a directory does not exist it will
be silently ignored. If <dir> is a symlink to a directory, just the symlink will
be removed. Use rm instead.
rename <oldname> <newname>
Rename a file or directory (on one volume). If file with the <newname> name already
exists, then it will be silently replaced.
rm [-rRf] <file> <dir>...
Remove the files <file> or directories dir. Use -r or -R to remove directories and
their contents recursively. If any of the listed files/directories do not exist,
the command returns a non-zero exit code, but no message is logged. The -f option
changes the behavior to return a zero exit code (i.e. success) in such situations
instead.
server Launch cmake-server(7) mode.
sleep <number>...
Sleep for given number of seconds.
tar [cxt][vf][zjJ] file.tar [<options>] [--] [<pathname>...]
Create or extract a tar or zip archive. Options are:
c Create a new archive containing the specified files. If used, the
<pathname>... argument is mandatory.
x Extract to disk from the archive. The <pathname>... argument could be used
to extract only selected files or directories. When extracting selected
files or directories, you must provide their exact names including the path,
as printed by list (-t).
t List archive contents. The <pathname>... argument could be used to list
only selected files or directories.
v Produce verbose output.
z Compress the resulting archive with gzip.
j Compress the resulting archive with bzip2.
J Compress the resulting archive with XZ.
--zstd Compress the resulting archive with Zstandard.
--files-from=<file>
Read file names from the given file, one per line. Blank lines are ignored.
Lines may not start in - except for --add-file=<name> to add files whose
names start in -.
--format=<format>
Specify the format of the archive to be created. Supported formats are:
7zip, gnutar, pax, paxr (restricted pax, default), and zip.
--mtime=<date>
Specify modification time recorded in tarball entries.
-- Stop interpreting options and treat all remaining arguments as file names,
even if they start with -.
time <command> [<args>...]
Run command and display elapsed time.
touch <file>...
Creates <file> if file do not exist. If <file> exists, it is changing <file>
access and modification times.
touch_nocreate <file>...
Touch a file if it exists but do not create it. If a file does not exist it will
be silently ignored.
true Do nothing, with an exit code of 0.
Windows-specific Command-Line Tools
The following cmake -E commands are available only on Windows:
delete_regv <key>
Delete Windows registry value.
env_vs8_wince <sdkname>
Displays a batch file which sets the environment for the provided Windows CE SDK

RUN THE FIND-PACKAGE TOOL
CMake provides a pkg-config like helper for Makefile-based projects:
cmake --find-package [<options>]
It searches a package using find_package() and prints the resulting flags to stdout. This
can be used instead of pkg-config to find installed libraries in plain Makefile-based
projects or in autoconf-based projects (via share/aclocal/cmake.m4).
NOTE:
This mode is not well-supported due to some technical limitations. It is kept for
compatibility but should not be used in new projects.
