Building of CMake project is usually performed in 2 steps:

  1. Generation of project for build system
  2. Building generated project with build system

Generation of project for build system

Assuming current directory is asio_samples_build_dir.

Windows Command Prompt, Visual Studio CMake generator:

cmake ... -G "%cmake_generator%" -A "%cmake_platform%" "%asio_samples_home_dir%"

Windows Command Prompt, NMake / MinGW makefiles CMake generator

cmake ... -G "%cmake_generator%" "%asio_samples_home_dir%"

*nix shell

cmake ... -G "${cmake_generator}" "${asio_samples_home_dir}"

where ... are optional parameters which are described below.

Use MA_TESTS CMake variable to exclude tests from build (tests are included by default):

cmake -D MA_TESTS=OFF ...

CMake project uses CMake find modules, so most of parameters comes from these CMake modules:

  • FindBoost CMake module

    CMake variables which can be specified in command line to locate and configure Boost:

    • BOOST_INCLUDEDIR - Boost headers directory

      Windows Command Prompt:

      -D BOOST_INCLUDEDIR="%boost_headers_dir%"

      *nix shell

      -D BOOST_INCLUDEDIR="${boost_headers_dir}"

    • BOOST_LIBRARYDIR - Boost libraries directory

      Windows Command Prompt:

      -D BOOST_LIBRARYDIR="%boost_libs_dir%"

      *nix shell

      -D BOOST_LIBRARYDIR="${boost_libs_dir}"

    • Boost_USE_STATIC_LIBS - force usage of static Boost, possible values are ON (use static libraries) and OFF (linkage type depends on platform)

    • Boost_NO_SYSTEM_PATHS - do not search for Boost in default system locations

  • cmake-qt CMake module (refer to Qt cmake manual also)

    CMake variables which can be specified in command line to locate Qt 5.x:

    • Qt5Core_DIR

      Windows Command Prompt:

      -D Qt5Core_DIR="%qt5_home_dir%/lib/cmake/Qt5Core"

      *nix shell

      -D Qt5Core_DIR="${qt5_home_dir}/lib/cmake/Qt5Core"

    • Qt5Gui_DIR

      Windows Command Prompt:

      -D Qt5Gui_DIR="%qt5_home_dir%/lib/cmake/Qt5Gui"

      *nix shell

      -D Qt5Gui_DIR="${qt5_home_dir}/lib/cmake/Qt5Gui"

    • Qt5Widgets_DIR

      Windows Command Prompt:

      -D Qt5Widgets_DIR="%qt5_home_dir%/lib/cmake/Qt5Widgets"

      *nix shell

      -D Qt5Widgets_DIR="${qt5_home_dir}/lib/cmake/Qt5Widgets"

    CMake variables which can be specified in command line to locate Qt 4.x:

    • QT_QMAKE_EXECUTABLE - path to qmake executable

      Windows Command Prompt:

      -D QT_QMAKE_EXECUTABLE="%qt4_home_dir%/bin/qmake.exe"

      *nix shell

      -D QT_QMAKE_EXECUTABLE="${qt4_home_dir}/bin/qmake.exe"

    MA_QT CMake variable can be used to avoid usage of Qt and to skip examples using Qt. Possible values are:

    • ON (default) - search for (require) and use Qt
    • OFF - do not search for Qt and skip building the parts which use Qt

  • FindGTest CMake module

    CMake variables which can be specified in command line to locate Google Test:

    • GTEST_ROOT - Google Test home directory

      Windows Command Prompt:

      -D GTEST_ROOT="%gtest_home_dir%"

      *nix shell

      -D GTEST_ROOT="${gtest_home_dir}"

    Note that if Google Test was built with CMake and MS Visual Studio then you have to "install" it somehow - just copying results of build (add "d" postfix into the name of debug artifacts) into Google Test root directory (or into "lib" sub-directory) would be enough for FindGTest.

    There is a copy of Google Test shipped as part of CMake project (refer to 3rdparty/gtest directory). It will be used in case FindGTest fails to find Google Test (so GTEST_ROOT is optional). Note that -D gtest_force_shared_crt=ON command line parameter is required in case shared C/C++ runtime is planned to be used with Google Test on Windows.

  • FindICU CMake module

    Used only if static Qt 5.x is identified.

    CMake variables which can be specified in command line to locate ICU:

    • ICU_ROOT - ICU home directory

      Windows Command Prompt:

      -D ICU_ROOT="%icu_home_dir%"

      *nix shell

      -D ICU_ROOT="${icu_home_dir}"

To build with static C/C++ runtime:

  • Use CMAKE_USER_MAKE_RULES_OVERRIDE CMake variable pointing to cmake/static_c_runtime_overrides.cmake

    Windows Command Prompt:

    -D CMAKE_USER_MAKE_RULES_OVERRIDE="%asio_samples_home_dir%/cmake/static_c_runtime_overrides.cmake"

    *nix shell

    -D CMAKE_USER_MAKE_RULES_OVERRIDE="${asio_samples_home_dir}/cmake/static_c_runtime_overrides.cmake"

  • Use CMAKE_USER_MAKE_RULES_OVERRIDE_CXX CMake variable pointing to cmake/static_cxx_runtime_overrides.cmake

    Windows Command Prompt:

    -D CMAKE_USER_MAKE_RULES_OVERRIDE_CXX="%asio_samples_home_dir%/cmake/static_cxx_runtime_overrides.cmake"

    *nix shell

    -D CMAKE_USER_MAKE_RULES_OVERRIDE_CXX="${asio_samples_home_dir}/cmake/static_cxx_runtime_overrides.cmake"

  • Static build of Qt

  • ICU_ROOT CMake variable pointing to ICU home directory (static build, required for Qt).

Note that on Windows cmake-qt searches for some system libraries (OpenGL) therefore to work correctly CMake should be executed after Windows SDK environment was set up (even if Visual Studio generator is used).

The CMake project searches for Qt 5.x first and if Qt 5.x is not found then it searches for Qt 4.x. This can be changed with MA_QT_MAJOR_VERSION CMake variable which can be specified in command line.

Possible values are:

  • 4 - search for Qt 4.x only

    -D MA_QT_MAJOR_VERSION=4

  • 5 - search for Qt 5.x only

    -D MA_QT_MAJOR_VERSION=5

Building generated project with build system

Building of generated project can be done using chosen (during generation of project) build system or using CMake.

CMake command to build generated project (Windows Command Prompt):

cmake --build "%asio_samples_build_dir%" --config "%build_type%"

CMake command to build generated project (*nix shell):

cmake --build "${asio_samples_build_dir}" --config "${build_type}"

Running tests

Assuming current directory is asio_samples_build_dir.

CTest command to run built tests (Windows Command Prompt):

ctest --build-config "%build_type%"

CTest command to run built tests (*nix shell):

ctest --build-config "${build_type}"
