    \title CMake presets

    \brief Examples of supported CMake presets.

    \c CMakePresets.json has options for project-wide builds, whereas
    \c CMakeUserPresets.json has options for your local builds.

    Create the presets files in the format described in
    \l {CMake: cmake-presets(7)} and store them in the project's root directory.
    You can then see them in the \l {Projects} view.

    \QC supports \e configure, \e build, and \e test presets up to version 10
    (introduced in CMake 3.31), but does not enforce version checking.
    It reads and uses all the fields from version 10 if present.

    You can import the presets the first time you \l {Open projects}
    {open a project}, when no \c CMakeLists.txt.user file exists or you have
    disabled all kits in the project.

    \image {qtcreator-cmake-presets-configure.webp} {Opening a project that has CMake presets}

    You can view the presets in the \uicontrol {Initial Configuration} field and
    in the environment configuration field below it.

    \image {qtcreator-cmake-presets-environment.webp} {CMake environment configuration}

    \QC watches the \c CMakePresets.json presets files for changes.
    To manually update changes to the files, go to \uicontrol Build,
    select \uicontrol {Reload CMake Presets}, and then select the presets file
    to load.

    \section1 Configure presets

    The following configure presets instruct CMake to use the default generator
    on the platform and specify the build directory for all build types.
    \c NOT_COMMON_VALUE is displayed in \uicontrol {Initial Parameters}
    and \c AN_ENVIRONMENT_FLAG in the environment configuration field.

    \code
    {
      "version": 1,
      "configurePresets": [
        {
          "name": "preset",
          "displayName": "preset",
          "binaryDir": "${sourceDir}/build/preset",
          "cacheVariables": {
            "NOT_COMMON_VALUE": "NOT_COMMON_VALUE"
            },
          "environment": {
            "AN_ENVIRONMENT_FLAG": "1"
            }
          },
          "vendor": {
            "qt.io/QtCreator/1.0": {
               "AskBeforePresetsReload": false,
               "AskReConfigureInitialParams": false,
               "AutorunCMake": false,
               "PackageManagerAutoSetup": false,
               "ShowAdvancedOptionsByDefault": true,
               "ShowSourceSubFolders": false,
               "UseJunctionsForSourceAndBuildDirectories": true
               }
          }
      ]
    }
    \endcode

    For more information about the CMake project settings in the \c vendor
    section, see \l {CMake \QC vendor presets}.

    \section1 MinGW example

    The following example configures a Qt project with:

    \list
        \li MinGW compiler
        \li build directory – \c <sourceDir>/build-release
        \li build type – \c CMAKE_BUILD_TYPE as \c Release
        \li generator – MinGW Makefiles
        \li path to a CMake executable
        \li path to the Qt installation via \c CMAKE_PREFIX_PATH
        \li GNU gdb 11.2.0 for MinGW 11.2.0 64-bit debugger
    \endlist

    \code
    {
      "version": 1,
      "configurePresets": [
        {
          "name": "mingw",
          "displayName": "MinGW 11.2.0",
          "generator": "MinGW Makefiles",
          "binaryDir": "${sourceDir}/build-release",
          "cmakeExecutable": "C:/Qt/Tools/CMake_64/bin/cmake.exe",
          "cacheVariables": {
            "CMAKE_BUILD_TYPE": "Release",
            "CMAKE_PREFIX_PATH": "C:/Qt/6.4.0/mingw_64"
          },
          "environment": {
            "PATH": "C:/Qt/Tools/mingw1120_64/bin;$penv{PATH}"
          },
          "vendor": {
            "qt.io/QtCreator/1.0": {
              "debugger": {
                "DisplayName": "GNU gdb 11.2.0 for MinGW 11.2.0 64-bit",
                "Abis": ["x86-windows-msys-pe-64bit"],
                "Binary": "C:/Qt/Tools/mingw1120_64/bin/gdb.exe",
                "EngineType": 1,
                "Version": "11.2.0"
              }
            }
          }
      ]
    }
    \endcode

    To speed up the process on Windows, specify the \c CMAKE_C_COMPILER and
    \c CMAKE_CXX_COMPILER in the \c cacheVariables section.

    For possible values of some of the \c debugger preferences, see
    \l {CMake \QC vendor presets}.

    \section1 Ninja generator example

    The following configure and build presets set Ninja Multi-Config as the
    generator, add \c Debug and \c Release build steps, and specify the path
    to \c ninja.exe as a value of the \c CMAKE_MAKE_PROGRAM variable:

    \code
    {
      "version": 2,
      "configurePresets": [
        {
          "name": "ninja-nmc",
          "displayName": "Ninja Multi-Config MinGW",
          "generator": "Ninja Multi-Config",
          "binaryDir": "${sourceDir}/build",
          "cacheVariables": {
            "CMAKE_CONFIGURATION_TYPES": "Debug;Release",
            "CMAKE_PREFIX_PATH": "C:/Qt/6.4.0/mingw_64",
            "CMAKE_MAKE_PROGRAM": "C:/Qt/Tools/Ninja/ninja.exe"
          },
          "environment": {
            "PATH": "c:/Qt/Tools/mingw1120_64/bin;$penv{PATH}"
          }
        }
      ],
      "buildPresets": [
        {
          "name": "release",
          "displayName": "Ninja Release",
          "configurePreset": "ninja-nmc",
          "configuration": "Release"
        },
        {
          "name": "debug",
          "displayName": "Ninja Debug",
          "configurePreset": "ninja-nmc",
          "configuration": "Debug"
        }
      ]
    }
    \endcode

    This example assumes that the CMake executable path is set in
    \preferences > \uicontrol CMake >
    \uicontrol Tools.

    \section1 MSVC example

    When using MSVC compilers with NMAKE Makefiles, Ninja, or Ninja
    Multi-Config generators, you can use the \c external strategy for
    the \c architecture and \c toolset fields. This lets \QC set up
    the Visual C++ environment before invoking CMake.

    For example:

    \code
    "generator": "Ninja Multi-Config",
    "toolset": {
      "value": "v142,host=x64",
      "strategy": "external"
    },
    "architecture": {
      "value": "x64",
      "strategy": "external"
    },
    \endcode

    If you use MSVC compilers with non-VS generators and have several compilers
    in the \c PATH, you might also have to specify the compiler to use in
    \c cacheVariables or \c environmentVariables:

    \code
    "generator": "Ninja Multi-Config",
    "toolset": {
      "value": "v142,host=x64",
      "strategy": "external"
    },
    "architecture": {
      "value": "x64",
      "strategy": "external"
    },
    "cacheVariables": {
      "CMAKE_C_COMPILER": "cl.exe",
      "CMAKE_CXX_COMPILER": "cl.exe"
    }
    \endcode

    \section1 Cross-compilation example

    The following example configures a Qt project for cross-compilation on \macos
    for Windows and running with the \c wine emulator on \macos:

    \list
        \li generator – Ninja
        \li build directory – \c <sourceDir>/build-release
        \li LLVM/MinGW toolchain
        \li configuration type – \c CMAKE_BUILD_TYPE as \c Release
        \li LLDB 18.1.6 debugger
        \li \c wine emulator
    \endlist

    \code
    {
      "version": 4,
      "configurePresets": [
        {
          "name": "llvm-mingw",
          "displayName": "LLVM-MinGW 18.1.6",
          "generator": "Ninja",
          "binaryDir": "${sourceDir}/build-release",
          "toolchainFile": "llvm-mingw.cmake",
          "cacheVariables": {
            "CMAKE_BUILD_TYPE": "Release",
            "CMAKE_CROSSCOMPILING_EMULATOR": "/opt/homebrew/bin/wine"
          },
          "vendor": {
            "qt.io/QtCreator/1.0": {
              "debugger": {
                "DisplayName": "LLDB 18.1.6 (CMake Preset)",
                "Abis": ["x86-darwin-generic-mach_o-64bit", "arm-darwin-generic-mach_o-64bit"],
                "Binary": "/Users/jdoe/llvm-mingw/bin/lldb",
                "EngineType": 256,
                "Version": "18.1.6"
              }
            }
          }
        }
      ]
    }
    \endcode

    \section1 Using conditions

    The following configure presets are used if they match \c condition. That is,
    if the \c hostSystemName equals \c Linux, the \c linux presets are used and
    if it equals \c Windows, the \c windows presets are used.

    \code
    {
      "version": 3,
      "configurePresets": [
        {
          "name": "linux",
          "displayName": "Linux GCC",
          "binaryDir": "${sourceDir}/build",
          "cacheVariables": {
            "CMAKE_PREFIX_PATH": "$env{HOME}/Qt/6.4.0/gcc_64"
          },
          "condition": {
            "type": "equals",
            "lhs": "${hostSystemName}",
            "rhs": "Linux"
          }
        },
        {
          "name": "windows",
          "displayName": "Windows MSVC",
          "binaryDir": "${sourceDir}/build",
          "cacheVariables": {
            "CMAKE_PREFIX_PATH": "$env{SYSTEMDRIVE}/Qt/6.4.0/msvc2019_64"
          },
          "condition": {
            "type": "equals",
            "lhs": "${hostSystemName}",
            "rhs": "Windows"
          }
        }
      ]
    }
    \endcode

    \section1 Test presets

    The following test presets instruct CMake to stop test execution and
    print output from the test program upon failure, as well as display an
    error if the test cannot be found.

    \code [json]
    {
      "version": 3,
      "testPresets": [
      {
        "name": "default",
        "configurePreset": "default",
        "output": {"outputOnFailure": true},
        "execution": {"noTestsAction": "error", "stopOnFailure": true}
        }
      ],
    }
    \endcode
