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.

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.

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.

-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>

Reads a preset from <path-to-source>/CMakePresets.json and <path-to-source>/CMakeUserPresets.json. The preset specifies the generator and the build directory, and optionally a list of variables and other arguments to pass to CMake. 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.

CMake provides a command-line signature to build an already-generated project binary tree:

cmake --build <dir> [<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 and must be first.

--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.

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.

cmake --open <dir>

Open the generated project in the associated application. This is only supported by some generators.

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).

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.

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.

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.

Do nothing, with an exit code of 1.

make_directory <dir>...

Create <dir> directories. If necessary, create parent directories too. If a directory already exists it will be silently ignored.

md5sum <file>...

Create MD5 checksum of files in md5sum compatible format:

351abe79cd3800b38cdfb25d45015a15  file1.txt052f86c15bbde68af55c7f7b340ab639  file2.txt

remove [-f] <file>...

Deprecated since version 3.17.

Remove the file(s). The planned behaviour 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 installed in VS2005.

env_vs9_wince <sdkname>

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.

To print selected pages from the CMake documentation, use

cmake --help[-<topic>]

with one of the following options:

--help,-help,-usage,-h,-H,/?

Print usage information and exit.

Usage describes the basic command line interface and its options.

--version,-version,/V [<f>]

Show program name/version banner and exit.

If a file is specified, the version is written into it. The help is printed to a named <f>ile if given.

--help-full [<f>]

Print all help manuals and exit.

All manuals are printed in a human-readable text format. The help is printed to a named <f>ile if given.

--help-manual <man> [<f>]

Print one help manual and exit.

The specified manual is printed in a human-readable text format. The help is printed to a named <f>ile if given.

--help-manual-list [<f>]

List help manuals available and exit.

The list contains all manuals for which help may be obtained by using the --help-manual option followed by a manual name. The help is printed to a named <f>ile if given.

--help-command <cmd> [<f>]

Print help for one command and exit.
