36 The cmake executable is the command-line interface of the cross-plat‐
37 form buildsystem generator CMake. The above Synopsis lists various
38 actions the tool can perform as described in sections below.
39
40 To build a software project with CMake, Generate a Project Buildsystem.
41 Optionally use cmake to Build a Project, Install a Project or just run
42 the corresponding build tool (e.g. make) directly. cmake can also be
43 used to View Help.
44
45 The other actions are meant for use by software developers writing
46 scripts in the CMake language to support their builds.
47
48 For graphical user interfaces that may be used in place of cmake, see
49 ccmake and cmake-gui. For command-line interfaces to the CMake testing
50 and packaging facilities, see ctest and cpack.
51
52 For more information on CMake at large, see also the links at the end
53 of this manual.
54
56 A buildsystem describes how to build a project’s executables and
57 libraries from its source code using a build tool to automate the
58 process. For example, a buildsystem may be a Makefile for use with a
59 command-line make tool or a project file for an Integrated Development
60 Environment (IDE). In order to avoid maintaining multiple such
61 buildsystems, a project may specify its buildsystem abstractly using
62 files written in the CMake language. From these files CMake generates
63 a preferred buildsystem locally for each user through a backend called
64 a generator.
65
66 To generate a buildsystem with CMake, the following must be selected:
67
68 Source Tree
69 The top-level directory containing source files provided by the
70 project. The project specifies its buildsystem using files as
71 described in the cmake-language(7) manual, starting with a
72 top-level file named CMakeLists.txt. These files specify build
73 targets and their dependencies as described in the
74 cmake-buildsystem(7) manual.
75
76 Build Tree
77 The top-level directory in which buildsystem files and build
78 output artifacts (e.g. executables and libraries) are to be
79 stored. CMake will write a CMakeCache.txt file to identify the
80 directory as a build tree and store persistent information such
81 as buildsystem configuration options.
82
83 To maintain a pristine source tree, perform an out-of-source
84 build by using a separate dedicated build tree. An in-source
85 build in which the build tree is placed in the same directory as
86 the source tree is also supported, but discouraged.
87
88 Generator
89 This chooses the kind of buildsystem to generate. See the
90 cmake-generators(7) manual for documentation of all generators.
91 Run cmake --help to see a list of generators available locally.
92 Optionally use the -G option below to specify a generator, or
93 simply accept the default CMake chooses for the current plat‐
94 form.
95
96 When using one of the Command-Line Build Tool Generators CMake
97 expects that the environment needed by the compiler toolchain is
98 already configured in the shell. When using one of the IDE
99 Build Tool Generators, no particular environment is needed.
100
102 Run CMake with one of the following command signatures to specify the
103 source and build trees and generate a buildsystem:
104
105 cmake [<options>] <path-to-source>
106 Uses the current working directory as the build tree, and
107 <path-to-source> as the source tree. The specified path may be
108 absolute or relative to the current working directory. The
109 source tree must contain a CMakeLists.txt file and must not con‐
110 tain a CMakeCache.txt file because the latter identifies an
111 existing build tree. For example:
112
113 $ mkdir build ; cd build
114 $ cmake ../src
115
116 cmake [<options>] <path-to-existing-build>
117 Uses <path-to-existing-build> as the build tree, and loads the
118 path to the source tree from its CMakeCache.txt file, which must
119 have already been generated by a previous run of CMake. The
120 specified path may be absolute or relative to the current work‐
121 ing directory. For example:
122
123 $ cd build
124 $ cmake .
125
126 cmake [<options>] -S <path-to-source> -B <path-to-build>
127 Uses <path-to-build> as the build tree and <path-to-source> as
128 the source tree. The specified paths may be absolute or rela‐
129 tive to the current working directory. The source tree must
130 contain a CMakeLists.txt file. The build tree will be created
131 automatically if it does not already exist. For example:
132
133 $ cmake -S src -B build
134
135 In all cases the <options> may be zero or more of the Options below.
136
137 After generating a buildsystem one may use the corresponding native
138 build tool to build the project. For example, after using the Unix
139 Makefiles generator one may run make directly:
140
141 $ make
142 $ make install
143
144 Alternatively, one may use cmake to Build a Project by automatically
145 choosing and invoking the appropriate native build tool.
146
147 Options
148 -S <path-to-source>
149 Path to root directory of the CMake project to build.
150
151 -B <path-to-build>
152 Path to directory which CMake will use as the root of build
153 directory.
154
155 If the directory doesn’t already exist CMake will make it.
156
157 -C <initial-cache>
158 Pre-load a script to populate the cache.
159
160 When CMake is first run in an empty build tree, it creates a
161 CMakeCache.txt file and populates it with customizable settings
162 for the project. This option may be used to specify a file from
163 which to load cache entries before the first pass through the
164 project’s CMake listfiles. The loaded entries take priority
165 over the project’s default values. The given file should be a
166 CMake script containing set() commands that use the CACHE
167 option, not a cache-format file.
168
169 References to CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR within the
170 script evaluate to the top-level source and build tree.
171
172 -D <var>:<type>=<value>, -D <var>=<value>
173 Create or update a CMake CACHE entry.
174
175 When CMake is first run in an empty build tree, it creates a
176 CMakeCache.txt file and populates it with customizable settings
177 for the project. This option may be used to specify a setting
178 that takes priority over the project’s default value. The
179 option may be repeated for as many CACHE entries as desired.
180
181 If the :<type> portion is given it must be one of the types
182 specified by the set() command documentation for its CACHE sig‐
183 nature. If the :<type> portion is omitted the entry will be
184 created with no type if it does not exist with a type already.
185 If a command in the project sets the type to PATH or FILEPATH
186 then the <value> will be converted to an absolute path.
187
188 This option may also be given as a single argument:
189 -D<var>:<type>=<value> or -D<var>=<value>.
190
191 -U <globbing_expr>
192 Remove matching entries from CMake CACHE.
193
194 This option may be used to remove one or more variables from the
195 CMakeCache.txt file, globbing expressions using * and ? are sup‐
196 ported. The option may be repeated for as many CACHE entries as
197 desired.
198
199 Use with care, you can make your CMakeCache.txt non-working.
200
201 -G <generator-name>
202 Specify a build system generator.
203
204 CMake may support multiple native build systems on certain plat‐
205 forms. A generator is responsible for generating a particular
206 build system. Possible generator names are specified in the
207 cmake-generators(7) manual.
208
209 If not specified, CMake checks the CMAKE_GENERATOR environment
210 variable and otherwise falls back to a builtin default selec‐
211 tion.
212
213 -T <toolset-spec>
214 Toolset specification for the generator, if supported.
215
216 Some CMake generators support a toolset specification to tell
217 the native build system how to choose a compiler. See the
218 CMAKE_GENERATOR_TOOLSET variable for details.
219
220 -A <platform-name>
221 Specify platform name if supported by generator.
222
223 Some CMake generators support a platform name to be given to the
224 native build system to choose a compiler or SDK. See the
225 CMAKE_GENERATOR_PLATFORM variable for details.
226
227 -Wno-dev
228 Suppress developer warnings.
229
230 Suppress warnings that are meant for the author of the CMake‐
231 Lists.txt files. By default this will also turn off deprecation
232 warnings.
233
234 -Wdev Enable developer warnings.
235
236 Enable warnings that are meant for the author of the CMake‐
237 Lists.txt files. By default this will also turn on deprecation
238 warnings.
239
240 -Werror=dev
241 Make developer warnings errors.
242
243 Make warnings that are meant for the author of the CMake‐
244 Lists.txt files errors. By default this will also turn on depre‐
245 cated warnings as errors.
246
247 -Wno-error=dev
248 Make developer warnings not errors.
249
250 Make warnings that are meant for the author of the CMake‐
251 Lists.txt files not errors. By default this will also turn off
252 deprecated warnings as errors.
253
254 -Wdeprecated
255 Enable deprecated functionality warnings.
256
257 Enable warnings for usage of deprecated functionality, that are
258 meant for the author of the CMakeLists.txt files.
259
260 -Wno-deprecated
261 Suppress deprecated functionality warnings.
262
263 Suppress warnings for usage of deprecated functionality, that
264 are meant for the author of the CMakeLists.txt files.
265
266 -Werror=deprecated
267 Make deprecated macro and function warnings errors.
268
269 Make warnings for usage of deprecated macros and functions, that
270 are meant for the author of the CMakeLists.txt files, errors.
271
272 -Wno-error=deprecated
273 Make deprecated macro and function warnings not errors.
274
275 Make warnings for usage of deprecated macros and functions, that
276 are meant for the author of the CMakeLists.txt files, not
277 errors.
278
279 -L[A][H]
280 List non-advanced cached variables.
281
282 List CACHE variables will run CMake and list all the variables
283 from the CMake CACHE that are not marked as INTERNAL or
284 ADVANCED. This will effectively display current CMake settings,
285 which can then be changed with -D option. Changing some of the
286 variables may result in more variables being created. If A is
287 specified, then it will display also advanced variables. If H
288 is specified, it will also display help for each variable.
289
290 -N View mode only.
291
292 Only load the cache. Do not actually run configure and generate
293 steps.
294
295 --graphviz=[file]
296 Generate graphviz of dependencies, see CMakeGraphVizOptions for
297 more.
298
299 Generate a graphviz input file that will contain all the library
300 and executable dependencies in the project. See the documenta‐
301 tion for CMakeGraphVizOptions for more details.
302
303 --system-information [file]
304 Dump information about this system.
305
306 Dump a wide range of information about the current system. If
307 run from the top of a binary tree for a CMake project it will
308 dump additional information such as the cache, log files etc.
309
310 --log-level=<ERROR|WARNING|NOTICE|STATUS|VERBOSE|DEBUG|TRACE>
311 Set the log level.
312
313 The message() command will only output messages of the specified
314 log level or higher. The default log level is STATUS.
315
316 To make a log level persist between CMake runs, set CMAKE_MES‐
317 SAGE_LOG_LEVEL as a cache variable instead. If both the command
318 line option and the variable are given, the command line option
319 takes precedence.
320
321 For backward compatibility reasons, --loglevel is also accepted
322 as a synonym for this option.
323
324 --log-context
325 Enable the message() command outputting context attached to each
326 message.
327
328 This option turns on showing context for the current CMake run
329 only. To make showing the context persistent for all subsequent
330 CMake runs, set CMAKE_MESSAGE_CONTEXT_SHOW as a cache variable
331 instead. When this command line option is given, CMAKE_MES‐
332 SAGE_CONTEXT_SHOW is ignored.
333
334 --debug-trycompile
335 Do not delete the try_compile() build tree. Only useful on one
336 try_compile() at a time.
337
338 Do not delete the files and directories created for try_com‐
339 pile() calls. This is useful in debugging failed try_compiles.
340 It may however change the results of the try-compiles as old
341 junk from a previous try-compile may cause a different test to
342 either pass or fail incorrectly. This option is best used for
343 one try-compile at a time, and only when debugging.
344
345 --debug-output
346 Put cmake in a debug mode.
347
348 Print extra information during the cmake run like stack traces
349 with message(SEND_ERROR) calls.
350
351 --debug-find
352 Put cmake find commands in a debug mode.
353
354 Print extra find call information during the cmake run to stan‐
355 dard error. Output is designed for human consumption and not for
356 parsing. See also the CMAKE_FIND_DEBUG_MODE variable for debug‐
357 ging a more local part of the project.
358
359 --trace
360 Put cmake in trace mode.
361
362 Print a trace of all calls made and from where.
363
364 --trace-expand
365 Put cmake in trace mode.
366
367 Like --trace, but with variables expanded.
368
369 --trace-format=<format>
370 Put cmake in trace mode and sets the trace output format.
371
372 <format> can be one of the following values.
373
374 human Prints each trace line in a human-readable format.
375 This is the default format.
376
377 json-v1
378 Prints each line as a separate JSON document. Each
379 document is separated by a newline ( \n ). It is guar‐
380 anteed that no newline characters will be present
381 inside a JSON document.
382
383 JSON trace format:
384
385 {
386 "file": "/full/path/to/the/CMake/file.txt",
387 "line": 0,
388 "cmd": "add_executable",
389 "args": ["foo", "bar"],
390 "time": 1579512535.9687231,
391 "frame": 2
392 }
393
394 The members are:
395
396 file The full path to the CMake source file where
397 the function was called.
398
399 line The line in file of the function call.
400
401 cmd The name of the function that was called.
402
403 args A string list of all function parameters.
404
405 time Timestamp (seconds since epoch) of the function
406 call.
407
408 frame Stack frame depth of the function that was
409 called.
410
411 Additionally, the first JSON document outputted con‐
412 tains the version key for the current major and minor
413 version of the
414
415 JSON trace format:
416
417 {
418 "version": {
419 "major": 1,
420 "minor": 0
421 }
422 }
423
424 The members are:
425
426 version
427 Indicates the version of the JSON format. The
428 version has a major and minor components fol‐
429 lowing semantic version conventions.
430
431 --trace-source=<file>
432 Put cmake in trace mode, but output only lines of a specified
433 file.
434
435 Multiple options are allowed.
436
437 --trace-redirect=<file>
438 Put cmake in trace mode and redirect trace output to a file
439 instead of stderr.
440
441 --warn-uninitialized
442 Warn about uninitialized values.
443
444 Print a warning when an uninitialized variable is used.
445
446 --warn-unused-vars
447 Warn about unused variables.
448
449 Find variables that are declared or set, but not used.
450
451 --no-warn-unused-cli
452 Don’t warn about command line options.
453
454 Don’t find variables that are declared on the command line, but
455 not used.
456
457 --check-system-vars
458 Find problems with variable usage in system files.
459
460 Normally, unused and uninitialized variables are searched for
461 only in CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR. This flag tells
462 CMake to warn about other files as well.
463
465 CMake provides a command-line signature to build an already-generated
466 project binary tree:
467
468 cmake --build <dir> [<options>] [-- <build-tool-options>]
469
470 This abstracts a native build tool’s command-line interface with the
471 following options:
472
473 --build <dir>
474 Project binary directory to be built. This is required and must
475 be first.
476
477 --parallel [<jobs>], -j [<jobs>]
478 The maximum number of concurrent processes to use when building.
479 If <jobs> is omitted the native build tool’s default number is
480 used.
481
482 The CMAKE_BUILD_PARALLEL_LEVEL environment variable, if set,
483 specifies a default parallel level when this option is not
484 given.
485
486 Some native build tools always build in parallel. The use of
487 <jobs> value of 1 can be used to limit to a single job.
488
489 --target <tgt>..., -t <tgt>...
490 Build <tgt> instead of the default target. Multiple targets may
491 be given, separated by spaces.
492
493 --config <cfg>
494 For multi-configuration tools, choose configuration <cfg>.
495
496 --clean-first
497 Build target clean first, then build. (To clean only, use
498 --target clean.)
499
500 --use-stderr
501 Ignored. Behavior is default in CMake >= 3.0.
502
503 --verbose, -v
504 Enable verbose output - if supported - including the build com‐
505 mands to be executed.
506
507 This option can be omitted if VERBOSE environment variable or
508 CMAKE_VERBOSE_MAKEFILE cached variable is set.
509
510 -- Pass remaining options to the native tool.
511
512 Run cmake --build with no options for quick help.
513
515 CMake provides a command-line signature to install an already-generated
516 project binary tree:
517
518 cmake --install <dir> [<options>]
519
520 This may be used after building a project to run installation without
521 using the generated build system or the native build tool. The options
522 are:
523
524 --install <dir>
525 Project binary directory to install. This is required and must
526 be first.
527
528 --config <cfg>
529 For multi-configuration generators, choose configuration <cfg>.
530
531 --component <comp>
532 Component-based install. Only install component <comp>.
533
534 --prefix <prefix>
535 Override the installation prefix, CMAKE_INSTALL_PREFIX.
536
537 --strip
538 Strip before installing.
539
540 -v, --verbose
541 Enable verbose output.
542
543 This option can be omitted if VERBOSE environment variable is
544 set.
545
546 Run cmake --install with no options for quick help.
547
549 cmake --open <dir>
550
551 Open the generated project in the associated application. This is only
552 supported by some generators.
553
555 cmake [{-D <var>=<value>}...] -P <cmake-script-file>
556
557 Process the given cmake file as a script written in the CMake language.
558 No configure or generate step is performed and the cache is not modi‐
559 fied. If variables are defined using -D, this must be done before the
560 -P argument.
561
563 CMake provides builtin command-line tools through the signature
564
565 cmake -E <command> [<options>]
566
567 Run cmake -E or cmake -E help for a summary of commands. Available
568 commands are:
569
570 capabilities
571 Report cmake capabilities in JSON format. The output is a JSON
572 object with the following keys:
573
574 version
575 A JSON object with version information. Keys are:
576
577 string The full version string as displayed by cmake
578 --version.
579
580 major The major version number in integer form.
581
582 minor The minor version number in integer form.
583
584 patch The patch level in integer form.
585
586 suffix The cmake version suffix string.
587
588 isDirty
589 A bool that is set if the cmake build is from a
590 dirty tree.
591
592 generators
593 A list available generators. Each generator is a JSON
594 object with the following keys:
595
596 name A string containing the name of the generator.
597
598 toolsetSupport
599 true if the generator supports toolsets and false
600 otherwise.
601
602 platformSupport
603 true if the generator supports platforms and false
604 otherwise.
605
606 extraGenerators
607 A list of strings with all the extra generators
608 compatible with the generator.
609
610 fileApi
611 Optional member that is present when the
612 cmake-file-api(7) is available. The value is a JSON
613 object with one member:
614
615 requests
616 A JSON array containing zero or more supported
617 file-api requests. Each request is a JSON object
618 with members:
619
620 kind Specifies one of the supported file-api
621 object kinds.
622
623 version
624 A JSON array whose elements are each a JSON
625 object containing major and minor members
626 specifying non-negative integer version
627 components.
628
629 serverMode
630 true if cmake supports server-mode and false otherwise.
631
632 chdir <dir> <cmd> [<arg>...]
633 Change the current working directory and run a command.
634
635 compare_files [--ignore-eol] <file1> <file2>
636 Check if <file1> is same as <file2>. If files are the same, then
637 returns 0, if not it returns 1. The --ignore-eol option implies
638 line-wise comparison and ignores LF/CRLF differences.
639
640 copy <file>... <destination>
641 Copy files to <destination> (either file or directory). If mul‐
642 tiple files are specified, the <destination> must be directory
643 and it must exist. Wildcards are not supported. copy does fol‐
644 low symlinks. That means it does not copy symlinks, but the
645 files or directories it point to.
646
647 copy_directory <dir>... <destination>
648 Copy content of <dir>... directories to <destination> directory.
649 If <destination> directory does not exist it will be created.
650 copy_directory does follow symlinks.
651
652 copy_if_different <file>... <destination>
653 Copy files to <destination> (either file or directory) if they
654 have changed. If multiple files are specified, the <destina‐
655 tion> must be directory and it must exist. copy_if_different
656 does follow symlinks.

720 remove [-f] <file>...
721 Deprecated since version 3.17.
722
723
724 Remove the file(s). The planned behaviour was that if any of the
725 listed files already do not exist, the command returns a
726 non-zero exit code, but no message is logged. The -f option
727 changes the behavior to return a zero exit code (i.e. success)
728 in such situations instead. remove does not follow symlinks.
729 That means it remove only symlinks and not files it point to.
730
731 The implementation was buggy and always returned 0. It cannot be
732 fixed without breaking backwards compatibility. Use rm instead.
733
734 remove_directory <dir>...
735 Deprecated since version 3.17.
736
737
738 Remove <dir> directories and their contents. If a directory does
739 not exist it will be silently ignored. If <dir> is a symlink to
740 a directory, just the symlink will be removed. Use rm instead.
741
742 rename <oldname> <newname>
743 Rename a file or directory (on one volume). If file with the
744 <newname> name already exists, then it will be silently
745 replaced.
746
747 rm [-rRf] <file> <dir>...
748 Remove the files <file> or directories dir. Use -r or -R to
749 remove directories and their contents recursively. If any of
750 the listed files/directories do not exist, the command returns a
751 non-zero exit code, but no message is logged. The -f option
752 changes the behavior to return a zero exit code (i.e. success)
753 in such situations instead.
754
755 server Launch cmake-server(7) mode.
756
757 sleep <number>...
758 Sleep for given number of seconds.
759
760 tar [cxt][vf][zjJ] file.tar [<options>] [--] [<pathname>...]

762
763 c Create a new archive containing the specified files. If
764 used, the <pathname>... argument is mandatory.
765
766 x Extract to disk from the archive. The <pathname>...
767 argument could be used to extract only selected files or
768 directories. When extracting selected files or directo‐
769 ries, you must provide their exact names including the
770 path, as printed by list (-t).
771
772 t List archive contents. The <pathname>... argument could
773 be used to list only selected files or directories.
774
775 v Produce verbose output.
776
777 z Compress the resulting archive with gzip.
778
779 j Compress the resulting archive with bzip2.
780

782
783 --zstd Compress the resulting archive with Zstandard.
784
785 --files-from=<file>
786 Read file names from the given file, one per line. Blank
787 lines are ignored. Lines may not start in - except for
788 --add-file=<name> to add files whose names start in -.
789
790 --format=<format>
791 Specify the format of the archive to be created. Sup‐
792 ported formats are: 7zip, gnutar, pax, paxr (restricted
793 pax, default), and zip.
794
795 --mtime=<date>
796 Specify modification time recorded in tarball entries.
797
798 -- Stop interpreting options and treat all remaining argu‐
799 ments as file names, even if they start with -.
800
801 time <command> [<args>...]
802 Run command and display elapsed time.
803
804 touch <file>...
805 Creates <file> if file do not exist. If <file> exists, it is
806 changing <file> access and modification times.
807
808 touch_nocreate <file>...
809 Touch a file if it exists but do not create it. If a file does
810 not exist it will be silently ignored.
811
812 true Do nothing, with an exit code of 0.

814 Windows-specific Command-Line Tools
815 The following cmake -E commands are available only on Windows:
816
817 delete_regv <key>
818 Delete Windows registry value.
819
820 env_vs8_wince <sdkname>
821 Displays a batch file which sets the environment for the pro‐
822 vided Windows CE SDK installed in VS2005.
823
824 env_vs9_wince <sdkname>
825 Displays a batch file which sets the environment for the pro‐
826 vided Windows CE SDK installed in VS2008.
827
828 write_regv <key> <value>
829 Write Windows registry value.
830
832 CMake provides a pkg-config like helper for Makefile-based projects:
833
834 cmake --find-package [<options>]
835
836 It searches a package using find_package() and prints the resulting
837 flags to stdout. This can be used instead of pkg-config to find
838 installed libraries in plain Makefile-based projects or in auto‐
839 conf-based projects (via share/aclocal/cmake.m4).
840
841 NOTE:
842 This mode is not well-supported due to some technical limitations.
843 It is kept for compatibility but should not be used in new projects.
