Ubuntu Manpage: cmake-generators - CMake Generators Reference

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.

Visual Studio Generators
Visual Studio 6
Removed. This once generated Visual Studio 6 project files, but the generator has been
removed since CMake 3.6. It is still possible to build with VS 6 tools using the NMake
Makefiles generator.

Visual Studio 7
Removed. This once generated Visual Studio .NET 2002 project files, but the generator has
been removed since CMake 3.6. It is still possible to build with VS 7.0 tools using the
NMake Makefiles generator.

Visual Studio 7 .NET 2003
Removed. This once generated Visual Studio .NET 2003 project files, but the generator has
been removed since CMake 3.9. It is still possible to build with VS 7.1 tools using the
NMake Makefiles generator.

Visual Studio 8 2005
Removed. This once generated Visual Studio 8 2005 project files, but the generator has

Deprecated. Generates Visual Studio 9 2008 project files.

NOTE:
This generator is deprecated and will be removed in a future version of CMake. It will
still be possible to build with VS 9 2008 tools using the Visual Studio 12 2013
generator (or above, and with VS 10 2010 also installed) with CMAKE_GENERATOR_TOOLSET
set to v90, or by using the NMake Makefiles generator.

Platform Selection
The default target platform name (architecture) is Win32.

New in version 3.1: The CMAKE_GENERATOR_PLATFORM variable may be set, perhaps via the
cmake -A option, to specify a target platform name (architecture). For example:

the Visual Studio 12 2013 (or above) generator with CMAKE_GENERATOR_TOOLSET set to v100,
or by using the NMake Makefiles generator.

Visual Studio 11 2012
Deprecated. Generates Visual Studio 11 (VS 2012) project files.

NOTE:
This generator is deprecated and will be removed in a future version of CMake. It will
still be possible to build with VS 11 2012 tools using the Visual Studio 12 2013 (or
above) generator with CMAKE_GENERATOR_TOOLSET set to v110, or by using the NMake
Makefiles generator.

For compatibility with CMake versions prior to 3.0, one may specify this generator using
the name "Visual Studio 11" without the year component.

Project Types
Only Visual C++ and C# projects may be generated (and Fortran with Intel compiler
integration). Other types of projects (JavaScript, Database, Website, etc.) are not
supported.

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.

another toolset.

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).

Visual Studio 15 2017
New in version 3.7.1.

Generates Visual Studio 15 (VS 2017) project files.

Project Types
Only Visual C++ and C# projects may be generated (and Fortran with Intel compiler
integration). Other types of projects (JavaScript, Powershell, Python, etc.) are not
supported.

Instance Selection
New in version 3.11.

VS 2017 supports multiple installations on the same machine. The CMAKE_GENERATOR_INSTANCE
variable may be used to select one.

Platform Selection
The default target platform name (architecture) is Win32.

The CMAKE_GENERATOR_PLATFORM variable may be set, perhaps via the cmake -A option, to
specify a target platform name (architecture). For example:

• cmake -G "Visual Studio 15 2017" -A Win32

• cmake -G "Visual Studio 15 2017" -A x64

• cmake -G "Visual Studio 15 2017" -A ARM

• cmake -G "Visual Studio 15 2017" -A ARM64

For compatibility with CMake versions prior to 3.1, one may specify a target platform name
optionally at the end of the generator name. This is supported only for:

Visual Studio 15 2017 Win64
Specify target platform x64.

Visual Studio 15 2017 ARM
Specify target platform ARM.

Toolset Selection

New in version 3.14.

Generates Visual Studio 16 (VS 2019) project files.

Project Types
Only Visual C++ and C# projects may be generated (and Fortran with Intel compiler
integration). Other types of projects (JavaScript, Powershell, Python, etc.) are not
supported.

specify a target platform name (architecture). For example:

• cmake -G "Visual Studio 16 2019" -A Win32

• cmake -G "Visual Studio 16 2019" -A x64

• cmake -G "Visual Studio 16 2019" -A ARM

• cmake -G "Visual Studio 16 2019" -A ARM64

Toolset Selection
The v142 toolset that comes with Visual Studio 16 2019 is selected by default. The
CMAKE_GENERATOR_TOOLSET option may be set, perhaps via the cmake -T option, to specify
another toolset.

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 64-bit variant on x64 hosts
and the 32-bit variant otherwise. 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.

another toolset.

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 -A option.
Typical values of arm, ppc, 86, etcetera, are used.

• The variable GHS_TARGET_PLATFORM may be set, perhaps via the cmake -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 -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 -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 3.27.4 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 -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().

Limitations
The Xcode generator does not support per-configuration sources. Code like the following
will result in a generation error:

add_executable(MyApp mymain-$<CONFIG>.cpp)

EXTRA GENERATORS

Deprecated since version 3.27: Support for "Extra Generators" is deprecated and will be
removed from a future version of CMake. IDEs may use the cmake-file-api(7) to view
CMake-generated project build trees.

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
Deprecated since version 3.27: Support for Extra Generators is deprecated and will be
removed from a future version of CMake. IDEs may use the cmake-file-api(7) to view
CMake-generated project build trees.

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

removed from a future version of CMake. IDEs may use the cmake-file-api(7) to view
CMake-generated project build trees.

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

Eclipse CDT4
Deprecated since version 3.27: Support for Extra Generators is deprecated and will be
removed from a future version of CMake. IDEs may use the cmake-file-api(7) to view
CMake-generated project build trees.

Generates Eclipse CDT 4.0 project files.

Project files for Eclipse will be created in the top directory. In out of source builds,
a linked resource to the top level source directory will be created. 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.

This "extra" generator may be specified as:

Eclipse CDT4 - MinGW Makefiles

Kate
Deprecated since version 3.27: Support for Extra Generators is deprecated and will be
removed from a future version of CMake. IDEs may use the cmake-file-api(7) to view
CMake-generated project build trees.

Generates Kate project files.

A project file for Kate will be created in the top directory in the top level build
directory. To use it in Kate, the Project plugin must be enabled. The project file is
loaded in Kate by opening the ProjectName.kateproject file in the editor. If the Kate
Build-plugin is enabled, all targets generated by CMake are available for building.

This "extra" generator may be specified as:

Kate - MinGW Makefiles
