CMAKE-GENERATORS(7)

NAME
cmake-generators - CMake Generators Reference

INTRODUCTION

A CMake Generator is responsible for writing the input files for a native build system. Exactly one of the CMake Generators must be selected for a build tree to determine what native build system is to be used. Optionally one of the Extra Generators may be selected as a variant of some of the Command-Line Build Tool Generators to produce project files for an auxiliary IDE.

CMake Generators are platform-specific so each may be available only on certain platforms. The cmake(1) command-line tool --help output lists available generators on the current platform. Use its -G option to specify the generator for a new build tree. The cmake-gui(1) offers interactive selection of a generator when creating a new build tree.

CMAKE GENERATORS

  Command-Line Build Tool Generators

These generators support command-line build tools. In order to use them, one must launch CMake from a command-line prompt whose environment is already configured for the chosen compiler and build tool.

  Makefile Generators

  Borland Makefiles

Generates Borland makefiles.

  MSYS Makefiles

Generates makefiles for use with MSYS (Minimal SYStem) make under the MSYS shell.

Use this generator in a MSYS shell prompt and using make as the build tool. The generated makefiles use /bin/sh as the shell to launch build rules. They are not compatible with a Windows command prompt.

To build under a Windows command prompt, use the MinGW Makefiles generator.

  MinGW Makefiles

Generates makefiles for use with mingw32-make under a Windows command prompt.

Use this generator under a Windows command prompt with MinGW (Minimalist GNU for Windows) in the PATH and using mingw32-make as the build tool. The generated makefiles use cmd.exe as the shell to launch build rules. They are not compatible with MSYS or a unix shell.

To build under the MSYS shell, use the MSYS Makefiles generator.

  NMake Makefiles

Generates NMake makefiles.

  NMake Makefiles JOM

Generates JOM makefiles.

New in version 3.8: CodeBlocks generator can be used as an extra generator.

  Unix Makefiles

Generates standard UNIX makefiles.

A hierarchy of UNIX makefiles is generated into the build tree. Use any standard UNIX-style make program to build the project through the all target and install the project through the install (or install/strip) target.

For each subdirectory sub/dir of the project a UNIX makefile will be created, containing the following targets:

all Depends on all targets required by the subdirectory.

install
    Runs the install step in the subdirectory, if any.

install/strip
    Runs the install step in the subdirectory followed by a CMAKE_STRIP command, if any.

    The CMAKE_STRIP variable will contain the platform's strip utility, which removes symbols information from generated binaries.

test
    Runs the test step in the subdirectory, if any.

package
    Runs the package step in the subdirectory, if any.

  Watcom WMake

Generates Watcom WMake makefiles.

  Ninja Generators

  Ninja

Generates build.ninja files.

A build.ninja file is generated into the build tree. Use the ninja program to build the project through the all target and install the project through the install (or install/strip) target.

For each subdirectory sub/dir of the project, additional targets are generated:

sub/dir/all New in version 3.6: Depends on all targets required by the subdirectory.

sub/dir/install New in version 3.7: Runs the install step in the subdirectory, if any.

sub/dir/install/strip New in version 3.7: Runs the install step in the subdirectory followed by a CMAKE_STRIP command, if any.

The CMAKE_STRIP variable will contain the platform's strip utility, which removes symbols information from generated binaries.

sub/dir/test New in version 3.7: Runs the test step in the subdirectory, if any.

sub/dir/package New in version 3.7: Runs the package step in the subdirectory, if any.

  Fortran Support

New in version 3.7.

The Ninja generator conditionally supports Fortran when the ninja tool is at least version 1.10 (which has the required features).

  Swift Support

New in version 3.15.

The Swift support is experimental, not considered stable, and may change in future releases of CMake.

  See Also

New in version 3.17: The Ninja Multi-Config generator is similar to the Ninja generator, but generates multiple configurations at once.

  Ninja Multi-Config

New in version 3.17.

Generates multiple build-<Config>.ninja files.

This generator is very much like the Ninja generator, but with some key differences. Only these differences will be discussed in this document.

Unlike the Ninja generator, Ninja Multi-Config generates multiple configurations at once with CMAKE_CONFIGURATION_TYPES instead of only one configuration with CMAKE_BUILD_TYPE. One build-<Config>.ninja file will be generated for each of these configurations (with <Config> being the configuration name.) These files are intended to be run with ninja -f build-<Config>.ninja. A build.ninja file is also generated, using the configuration from either CMAKE_DEFAULT_BUILD_TYPE or the first item from CMAKE_CONFIGURATION_TYPES.

cmake --build . --config <Config> will always use build-<Config>.ninja to build. If no --config argument is specified, cmake --build . will use build.ninja.

Each build-<Config>.ninja file contains <target> targets as well as <target>:<Config> targets, where <Config> is the same as the configuration specified in build-<Config>.ninja Additionally, if cross-config mode is enabled, build-<Config>.ninja may contain <target>:<OtherConfig> targets, where <OtherConfig> is a cross-config, as well as <target>:all, which builds the target in all cross-configs. See below for how to enable cross-config mode.

The Ninja Multi-Config generator recognizes the following variables:

CMAKE_CONFIGURATION_TYPES
    Specifies the total set of configurations to build. Unlike with other multi-config generators, this variable has a value of Debug;Release;RelWithDebInfo by default.

CMAKE_CROSS_CONFIGS
    Specifies a semicolon-separated list of configurations available from all build-<Config>.ninja files.

CMAKE_DEFAULT_BUILD_TYPE
    Specifies the configuration to use by default in a build.ninja file.

CMAKE_DEFAULT_CONFIGS
    Specifies a semicolon-separated list of configurations to build for a target in build.ninja if no :<Config> suffix is specified.

    Consider the following example:

    cmake_minimum_required(VERSION 3.16)
    project(MultiConfigNinja C)
    add_executable(generator generator.c)
    add_custom_command(OUTPUT generated.c COMMAND generator generated.c)
    add_library(generated ${CMAKE_BINARY_DIR}/generated.c)

    Now assume you configure the project with Ninja Multi-Config and run one of the following commands:

    ninja -f build-Debug.ninja generated
    # OR
    cmake --build . --config Debug --target generated

    This would build the Debug configuration of generator, which would be used to generate generated.c, which would be used to build the Debug configuration of generated.

    But if CMAKE_CROSS_CONFIGS is set to all, and you run the following instead:

    ninja -f build-Release.ninja generated:Debug
    # OR
    cmake --build . --config Release --target generated:Debug

    This would build the Release configuration of generator, which would be used to generate generated.c, which would be used to build the Debug configuration of generated. This is useful for running a release-optimized version of a generator utility while still building the debug version of the targets built with the generated code.

  Custom Commands

New in version 3.20.

The Ninja Multi-Config generator adds extra capabilities to add_custom_command() and add_custom_target() through its cross-config mode. The COMMAND, DEPENDS, and WORKING_DIRECTORY arguments can be evaluated in the context of either the "command config" (the "native" configuration of the build-<Config>.ninja file in use) or the "output config" (the configuration used to evaluate the OUTPUT and BYPRODUCTS).

If either OUTPUT or BYPRODUCTS names a path that is common to more than one configuration (e.g. it does not use any generator expressions), all arguments are evaluated in the command config by default. If all OUTPUT and BYPRODUCTS paths are unique to each configuration (e.g. by using the $<CONFIG> generator expression), the first argument of COMMAND is still evaluated in the command config by default, while all subsequent arguments, as well as the arguments to DEPENDS and WORKING_DIRECTORY, are evaluated in the output config. These defaults can be overridden with the $<OUTPUT_CONFIG:...> and $<COMMAND_CONFIG:...> generator-expressions. Note that if a target is specified by its name in DEPENDS, or as the first argument of COMMAND, it is always evaluated in the command config, even if it is wrapped in $<OUTPUT_CONFIG:...> (because its plain name is not a generator expression).

As an example, consider the following:

add_custom_command(
  OUTPUT "$<CONFIG>.txt"
  COMMAND generator "$<CONFIG>.txt" "$<OUTPUT_CONFIG:$<CONFIG>>" "$<COMMAND_CONFIG:$<CONFIG>>"
  DEPENDS tgt1 "$<TARGET_FILE:tgt2>" "$<OUTPUT_CONFIG:$<TARGET_FILE:tgt3>>" "$<COMMAND_CONFIG:$<TARGET_FILE:tgt4>>"
  )

Assume that generator, tgt1, tgt2, tgt3, and tgt4 are all executable targets, and assume that $<CONFIG>.txt is built in the Debug output config using the Release command config. The Release build of the generator target is called with Debug.txt Debug Release as arguments. The command depends on the Release builds of tgt1 and tgt4, and the Debug builds of tgt2 and tgt3.

PRE_BUILD, PRE_LINK, and POST_BUILD custom commands for targets only get run in their "native" configuration (the Release configuration in the build-Release.ninja file) unless they have no BYPRODUCTS or their BYPRODUCTS are unique per config. Consider the following example:

add_executable(exe main.c)
add_custom_command(
  TARGET exe
  POST_BUILD
  COMMAND ${CMAKE_COMMAND} -E echo "Running no-byproduct command"
  )
add_custom_command(
  TARGET exe
  POST_BUILD
  COMMAND ${CMAKE_COMMAND} -E echo "Running separate-byproduct command for $<CONFIG>"
  BYPRODUCTS $<CONFIG>.txt
  )
add_custom_command(
  TARGET exe
  POST_BUILD
  COMMAND ${CMAKE_COMMAND} -E echo "Running common-byproduct command for $<CONFIG>"
  BYPRODUCTS exe.txt
  )

In this example, if you build exe:Debug in build-Release.ninja, the first and second custom commands get run, since their byproducts are unique per-config, but the last custom command does not. However, if you build exe:Release in build-Release.ninja, all three custom commands get run.

  IDE Build Tool Generators

These generators support Integrated Development Environment (IDE) project files. Since the IDEs configure their own environment one may launch CMake from any environment.

New in version 3.8: For each toolset that comes with this version of Visual Studio, there are variants that are themselves compiled for 32-bit (x86) and 64-bit (x64) hosts (independent of the architecture they target). By default this generator uses the 32-bit variant even on a 64-bit host. One may explicitly request use of either the 32-bit or 64-bit host tools by adding either host=x86 or host=x64 to the toolset specification. See the CMAKE_GENERATOR_TOOLSET variable for details.

By default this generator uses the 32-bit variant even on a 64-bit host. One may explicitly request use of either the 32-bit or 64-bit host tools by adding either host=x86 or host=x64 to the toolset specification. See the CMAKE_GENERATOR_TOOLSET variable for details.

New in version 3.14: Added support for host=x86 option.

  Windows 10 SDK Maximum Version for VS 2015

New in version 3.19.

Microsoft stated in a "Windows 10 October 2018 Update" blog post that Windows 10 SDK versions (15063, 16299, 17134, 17763) are not supported by VS 2015 and are only supported by VS 2017 and later. Therefore by default CMake automatically ignores Windows 10 SDKs beyond 10.0.14393.0.

However, there are other recommendations for certain driver/Win32 builds that indicate otherwise. A user can override this behavior by either setting the CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION_MAXIMUM to a false value or setting the CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION_MAXIMUM to the string value of the required maximum (e.g. 10.0.15063.0).

  Other Generators

  Green Hills MULTI

New in version 3.3.

New in version 3.15: Linux support.

Generates Green Hills MULTI project files (experimental, work-in-progress). The buildsystem has predetermined build-configuration settings that can be controlled via the CMAKE_BUILD_TYPE variable.

  Platform Selection

New in version 3.13.

The variable GHS_PRIMARY_TARGET can be used to select the target platform.
Sets primaryTarget entry in project file.

For example:

•   cmake -G "Green Hills MULTI" -D GHS_PRIMARY_TARGET=ppc_integrity.tgt

    Otherwise the primaryTarget will be composed from the values of CMAKE_GENERATOR_PLATFORM and GHS_TARGET_PLATFORM. Defaulting to the value of arm_integrity.tgt

•   The CMAKE_GENERATOR_PLATFORM variable may be set, perhaps via the cmake(1) -A option.
    Typical values of arm, ppc, 86, etcetera, are used.

•   The variable GHS_TARGET_PLATFORM may be set, perhaps via the cmake(1) -D option.
    Defaults to integrity.
    Usual values are integrity, threadx, uvelosity, velosity,
    vxworks, standalone.

    For example:

•   cmake -G "Green Hills MULTI" for arm_integrity.tgt.

•   cmake -G "Green Hills MULTI" -A 86 for 86_integrity.tgt.

•   cmake -G "Green Hills MULTI" -D GHS_TARGET_PLATFORM=standalone for arm_standalone.tgt.

•   cmake -G "Green Hills MULTI" -A ppc -D GHS_TARGET_PLATFORM=standalone for ppc_standalone.tgt.

  Toolset Selection

New in version 3.13.

The generator searches for the latest compiler or can be given a location to use. GHS_TOOLSET_ROOT is the directory that is checked for the latest compiler.

•   The CMAKE_GENERATOR_TOOLSET option may be set, perhaps via the cmake(1) -T option, to specify the location of the toolset. Both absolute and relative paths are valid. Paths are relative to GHS_TOOLSET_ROOT.

•   The variable GHS_TOOLSET_ROOT may be set, perhaps via the cmake(1) -D option.
    Root path for toolset searches and relative paths.
    Defaults to C:/ghs in Windows or /usr/ghs in Linux.

    For example, setting a specific compiler:

•   cmake -G "Green Hills MULTI" -T comp_201754 for /usr/ghs/comp_201754.

•   cmake -G "Green Hills MULTI" -T comp_201754 -D GHS_TOOLSET_ROOT=/opt/ghs for /opt/ghs/comp_201754.

•   cmake -G "Green Hills MULTI" -T /usr/ghs/comp_201554

•   cmake -G "Green Hills MULTI" -T C:/ghs/comp_201754

    For example, searching for latest compiler:

•   cmake -G "Green Hills MULTI" for searching /usr/ghs.

•   cmake -G "Green Hills MULTI -D GHS_TOOLSET_ROOT=/opt/ghs" for searching /opt/ghs.

    NOTE: The CMAKE_GENERATOR_TOOLSET should use CMake style paths.

  OS and BSP Selection

New in version 3.3.

Certain target platforms, like Integrity, require an OS. The RTOS directory path can be explicitly set using GHS_OS_DIR. Otherwise GHS_OS_ROOT will be searched for the latest Integrity RTOS.

If the target platform, like Integrity, requires a BSP name then it can be set via the GHS_BSP_NAME variable.

•   GHS_OS_DIR and GHS_OS_DIR_OPTION
    Sets -os_dir entry in project file.

    GHS_OS_DIR_OPTION default value is -os_dir.

    New in version 3.15: The GHS_OS_DIR_OPTION variable.

    For example:

•   cmake -G "Green Hills MULTI" -D GHS_OS_DIR=/usr/ghs/int1144

•   GHS_OS_ROOT
    Root path for RTOS searches.
    Defaults to C:/ghs in Windows or /usr/ghs in Linux.

    For example:

•   cmake -G "Green Hills MULTI" -D GHS_OS_ROOT=/opt/ghs

•   GHS_BSP_NAME
    Sets -bsp entry in project file.
    Defaults to sim<arch> for integrity platforms.

    For example:

•   cmake -G "Green Hills MULTI" for simarm on arm_integrity.tgt.

•   cmake -G "Green Hills MULTI" -A 86 for sim86 on 86_integrity.tgt.

•   cmake -G "Green Hills MULTI" -A ppc -D GHS_BSP_NAME=sim800 for sim800 on ppc_integrity.tgt.

•   cmake -G "Green Hills MULTI" -D GHS_PRIMARY_TARGET=ppc_integrity.tgt -D GHS_BSP_NAME=fsl-t1040 for fsl-t1040 on ppc_integrity.tgt.

  Target Properties

New in version 3.14.

The following properties are available:

•   GHS_INTEGRITY_APP

•   GHS_NO_SOURCE_GROUP_FILE

  MULTI Project Variables

New in version 3.3.

Adding a Customization file and macros are available through the use of the following variables:

•   GHS_CUSTOMIZATION - CMake path name to Customization File.

•   GHS_GPJ_MACROS - CMake list of Macros.

    NOTE: This generator is deemed experimental as of CMake 3.24.2 and is still a work in progress. Future versions of CMake may make breaking changes as the generator matures.

  Xcode

Generate Xcode project files.

Changed in version 3.15: This generator supports Xcode 5.0 and above.

  Toolset and Build System Selection

By default Xcode is allowed to select its own default toolchain. The CMAKE_GENERATOR_TOOLSET option may be set, perhaps via the cmake(1) -T option, to specify another toolset.

New in version 3.19: This generator supports toolset specification using one of these forms:

•   toolset

•   toolset[,key=value]*

•   key=value[,key=value]*

    The toolset specifies the toolset name. The selected toolset name is provided in the CMAKE_XCODE_PLATFORM_TOOLSET variable.

    The key=value pairs form a comma-separated list of options to specify generator-specific details of the toolset selection. Supported pairs are:

buildsystem=<variant>
    Specify the buildsystem variant to use. See the CMAKE_XCODE_BUILD_SYSTEM variable for allowed values.

    For example, to select the original build system under Xcode 12, run cmake(1) with the option -T buildsystem=1.

  Swift Support

New in version 3.4.

When using the Xcode generator with Xcode 6.1 or higher, one may enable the Swift language with the enable_language() command or the project().

EXTRA GENERATORS

Some of the CMake Generators listed in the cmake(1) command-line tool --help output may have variants that specify an extra generator for an auxiliary IDE tool. Such generator names have the form <extra-generator> - <main-generator>. The following extra generators are known to CMake.

  CodeBlocks

Generates CodeBlocks project files.

Project files for CodeBlocks will be created in the top directory and in every subdirectory which features a CMakeLists.txt file containing a project() call. Additionally a hierarchy of makefiles is generated into the build tree. The appropriate make program can build the project through the default all target. An install target is also provided.

New in version 3.10: The CMAKE_CODEBLOCKS_EXCLUDE_EXTERNAL_FILES variable may be set to ON to exclude any files which are located outside of the project root directory.

This "extra" generator may be specified as:

CodeBlocks - MinGW Makefiles
    Generate with MinGW Makefiles.

CodeBlocks - NMake Makefiles
    Generate with NMake Makefiles.

CodeBlocks - NMake Makefiles JOM
    New in version 3.8: Generate with NMake Makefiles JOM.

CodeBlocks - Ninja
    Generate with Ninja.

CodeBlocks - Unix Makefiles
    Generate with Unix Makefiles.

  CodeLite

Generates CodeLite project files.

Project files for CodeLite will be created in the top directory and in every subdirectory which features a CMakeLists.txt file containing a project() call. The appropriate make program can build the project through the default all target. An install target is also provided.

New in version 3.7: The CMAKE_CODELITE_USE_TARGETS variable may be set to ON to change the default behavior from projects to targets as the basis for project files.

This "extra" generator may be specified as:

CodeLite - MinGW Makefiles
    Generate with MinGW Makefiles.

CodeLite - NMake Makefiles
    Generate with NMake Makefiles.

CodeLite - Ninja
    Generate with Ninja.

CodeLite - Unix Makefiles
