2. Usage

2.1. Windows

Use CMake-GUI to generate Visual Studio 2010 project, then use Visual Studio to compile & run.

Here is a Tutorial: HOWTO: Win + CMake + Visual Studio 2010 · Issue #1 · district10/cmake-templates.

2.2. Linux

Most commonly, we build Makefile project:

# cd source dir (there should be a CMakeLists.txt)
mkdir build && cd build
cmake ..            # want a release build? try `cmake -DCMAKE_BUILD_TYPE=Release ..'
make

# then checkout the generated binary files

But we can build CodeBlocks projects too, see my tutorial: HOWTO: Linux + CMake + CodeBlocks + GNU Make · Issue #2 · district10/cmake-templates, or use qt-creator to open CMakeLists.txt directly, see my tutorial: HOWTO: Use Qt creator to Open CMakeLists.txt directly (will generate proper project files) · Issue #5 · district10/cmake-templates.

3. Examples

3.1. C Example

Simple C project.

project( C )
cmake_minimum_required( VERSION 2.6 )
add_executable( ${PROJECT_NAME} main.c )

cmake_minimum_required( ... ) is needed in root CMakeLists.txt, always.

The ${PROJECT_NAME} is variable with value C, which is set by the project( C ).

See c.

3.2. C++ Example

Simple C++ project.

project( CPP )
make_minimum_required( VERSION 2.6 )
file( GLOB SRCS *.c *.cpp *.cc *.h *.hpp )  # a variable called SRCS with all files whose path match "*.c *.cpp..."
add_executable( ${PROJECT_NAME} ${SRCS} )

See cpp.

3.3. C++11 Example

C++11 project.

include( CheckCXXCompilerFlag )
check_cxx_compiler_flag( "-std=c++11"   COMPILER_SUPPORTS_CXX11 )
check_cxx_compiler_flag( "-std=c++0x"   COMPILER_SUPPORTS_CXX0X )
if( COMPILER_SUPPORTS_CXX11 )
    if( CMAKE_COMPILER_IS_GNUCXX )
        set( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11" )
    else()
        set( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11" )
    endif()
elseif( COMPILER_SUPPORTS_CXX0X)
    set( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++0x" )
else()
    # MSVC, On by default (if available)
endif()

See cpp11.

I recommend Visual Studio 2015 Community Edition.

3.4. Example to Show How to Modualize Your Project

# root cmakelists.txt
project( MODULES )
cmake_minimum_required( VERSION 2.8.3 )

include_directories( ${CMAKE_SOURCE_DIR}/includes )

add_subdirectory( src )
add_subdirectory( demo )

# src dir
add_subdirectory( cubic )
add_subdirectory( extras )
add_subdirectory( square )

# cubic
add_library( LibCubic ${CUBICS} cubic.c )

# demo
project( CALC )
cmake_minimum_required( VERSION 2.6 )

set( EXTRA_LIBS ${EXTRA_LIBS} LibSquare )
set( EXTRA_LIBS ${EXTRA_LIBS} LibExtras )
set( EXTRA_LIBS ${EXTRA_LIBS} LibCubic )

add_executable( Calc calc.c )
target_link_libraries( Calc  ${EXTRA_LIBS} )

See modules.

3.5. Example with Support of Boost

project( BOOST )
cmake_minimum_required( VERSION 2.6 )

find_package( Boost REQUIRED )
INCLUDE_DIRECTORIES( ${Boost_INCLUDE_DIR} )
LINK_DIRECTORIES( ${Boost_LIBRARY_DIRS} )
set( Boost_USE_STATIC_LIBS        OFF )
set( Boost_USE_MULTITHREADED      ON )
set( Boost_USE_STATIC_RUNTIME     OFF )
set( BOOST_ALL_DYN_LINK           ON ) # force dynamic linking for all libraries

add_executable( ${PROJECT_NAME} main.cpp )
target_link_libraries( ${PROJECT_NAME} ${Boost_LIBRARIES} )

Ubuntu install: sudo apt-get install libboost-all-dev.

See boost.

3.6. Example with Support of OpenCV

Want to how to configure both opencv 2 & 3 on your system? Checkout my tutorial: HOWTO: OpenCV 2 & OpenCV 3 · Issue #4 · district10/cmake-templates.

opencv 2 or less

project( OPENCV )
cmake_minimum_required( VERSION 2.6 )

include( $ENV{OpenCV2_DIR}/OpenCVConfig.cmake ) # find_package( OpenCV REQUIRED )

message( STATUS "OpenCV library status:" )
message( STATUS "    version: ${OpenCV_VERSION}" )
message( STATUS "    libraries: ${OpenCV_LIBS}" )
message( STATUS "    include path: ${OpenCV_INCLUDE_DIRS}" )

include_directories( ${OpenCV_INCLUDE_DIRS} )

add_executable( ${PROJECT_NAME}  minarea.c )
target_link_libraries( ${PROJECT_NAME} ${OpenCV_LIBS} )

opencv 3

project( OPENCV3 )
cmake_minimum_required( VERSION 2.8 )

include( $ENV{OpenCV3_DIR}/OpenCVConfig.cmake ) # find_package( OpenCV REQUIRED )

message( STATUS "OpenCV library status:" )
message( STATUS "    version: ${OpenCV_VERSION}" )
message( STATUS "    libraries: ${OpenCV_LIBS}" )
message( STATUS "    include path: ${OpenCV_INCLUDE_DIRS}" )

include_directories( ${OpenCV_INCLUDE_DIRS} )

add_executable( ${PROJECT_NAME} example.cpp )
target_link_libraries( ${PROJECT_NAME} ${OpenCV_LIBS} )

See

opencv: for opencv2 or less (VS2010 😄, Linux ❓)
opencv3: for opencv3 (VS2010 ❓, Linux 😄)

3.7. Example with Support of Qt4

Be sure to make qmake caught by CMake, put it in your $PATH.

qt4 console

find_package( Qt4 REQUIRED )
include( ${QT_USE_FILE} )
set( QT_DONT_USE_QTGUI TRUE )

add_executable( ${PROJECT_NAME} main.cpp )
target_link_libraries( ${PROJECT_NAME}  ${QT_LIBRARIES} )

configure file

configure_file(
    "${PROJECT_SOURCE_DIR}/Configs.h.in"
    "${PROJECT_BINARY_DIR}/Configs.h" )

moc, uic

file( GLOB_RECURSE HDRS_FILES *.h *.hpp )
file( GLOB_RECURSE SRCS_FILES *.cpp )
file( GLOB_RECURSE UI_FILES *.ui )

qt4_wrap_cpp( MOC_SRCS ${HDRS_FILES} )
qt4_wrap_ui( UI_HDRS ${UI_FILES} )

source_group( "UI Files" FILES ${UI_FILES} )
source_group( "Generated Files" FILES ${MOC_SRCS} ${UI_HDRS} )

add_library( ${PROJECT_NAME} STATIC ${SRCS_FILES} ${UI_FILES} ${HDRS_FILES} ${MOC_SRCS} ${UI_HDRS} )
target_link_libraries( ${PROJECT_NAME} ${QT_LIBRARIES} )

Works like qmake -project, one ring to rule them all:

project( QT4 )
cmake_minimum_required( VERSION 2.6 )

find_package( Qt4 REQUIRED )
include( ${QT_USE_FILE} )

include_directories( ${CMAKE_SOURCE_DIR}/ )
include_directories( ${CMAKE_BINARY_DIR}/ )

# based on: https://cmake.org/Wiki/CMakeMacroFilterOut
macro( filter_out FILTERS INPUTS OUTPUTS )
    set( FOUT "" )
    foreach( INP ${INPUTS} )
        set( FILTERED 0 )
        foreach( FILT ${FILTERS} )
            if( ${FILTERED} EQUAL 0 )
                if( "${FILT}" STREQUAL "${INP}" )
                    set( FILTERED 1 )
                endif( "${FILT}" STREQUAL "${INP}" )
                if( ${INP} MATCHES ${FILT} )
                    set( FILTERED 1 )
                endif( ${INP} MATCHES ${FILT} )
            endif( ${FILTERED} EQUAL 0 )
        endforeach( FILT ${FILTERS} )
        if( ${FILTERED} EQUAL 0 )
            set( FOUT ${FOUT} ${INP} )
        endif( ${FILTERED} EQUAL 0 )
    endforeach( INP ${INPUTS} )
    set( ${OUTPUTS} ${FOUT} )
endmacro( filter_out FILTERS INPUTS OUTPUTS )

file( GLOB_RECURSE UI_FILES *.ui )
file( GLOB_RECURSE HDRS_FILES *.h *.hpp )
file( GLOB_RECURSE SRCS_FILES *.cpp *.c )
file( GLOB_RECURSE RCS_FILES *.qrc )

set( FILTERS ".*CompilerId.*" )
set( FILTERS ".*CMakeFiles/.*" )
filter_out("${FILTERS}" "${SRCS_FILES}" SRCS_FILES )

qt4_wrap_cpp( MOC_SRCS ${HDRS_FILES} )
qt4_wrap_ui( UI_HDRS ${UI_FILES} )
qt4_add_resources( RCS ${RCS_FILES} )

source_group( "UI Files" FILES ${UI_FILES} )
source_group( "Generated Files" FILES ${MOC_SRCS} ${UI_HDRS} )
source_group( "All Resource Files" FILES ${RCS} )

add_executable( ${PROJECT_NAME}
    ${MOC_SRCS}
    ${HDRS_FILES}
    ${SRCS_FILES}
    ${UI_FILES}
    ${UI_HDRS} ${RCS} )
target_link_libraries( ${PROJECT_NAME} ${QT_LIBRARIES} )

See

qt4 console application (VS2010 😄, Linux 😄)
qt4 GUI application (check out the configs.h.in file) (VS2010 😄, Linux 😄)
qt4 application for lazy people, works like qmake -project && qmake && make on Linux (VS2010 😄, Linux 😄)

3.8. Example with Support of Qt5

project( Qt5Project )
cmake_minimum_required( VERSION 2.8.11 )

#                                           root of your msvc14 x64 prebuild
set( CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} "C:/Qt/Qt5-msvc14/5.6/msvc2015_64" )
set( CMAKE_INCLUDE_CURRENT_DIR ON )
set( CMAKE_AUTOMOC ON )

find_package( Qt5Widgets REQUIRED )
qt5_wrap_ui( UI_HEADERS mainwindow.ui )
qt5_add_resources( QRCS resources.qrc )
add_executable( ${PROJECT_NAME} main.cpp mainwindow.cpp ${UI_HEADERS} ${QRCS} )
target_link_libraries( ${PROJECT_NAME} Qt5::Widgets )

See qt5 project.

3.9. Get'em Together (advanced examples)

This part is called CMake in Action.

ToyAuthor/luapp: Using lua in C++ style. Build system is CMake.
- a great cmake wrapper for lua, a great c++ wrapper for lua
- I forked it, and annotated (in chinese), it's really great! My fork: 4ker/luapp: Using lua in C++ style. Build system is CMake..
district10/algo: 重复造轮子。
- Libs
  - google test (gmock), for testing and benchmarking, etc
  - cppformat, the missing string formating lib
- modulized
- advanced linking style
https://github.com/district10/bcp/tree/standalone

4. TODO

More documentation
More elegant & illustrative examples
Planned Examples
- for Windows, link *.lib files
- for Linux, link *.a, *.so files, set rpath
- etc.

5. Snippets & Helper Functions

cpp -> exe

file( GLOB SRCS src/*.cpp)
foreach( src ${SRCS} )
    string( REGEX REPLACE "(^.*/|.cpp$)" "" exe ${src} )
    message( STATUS "${exe} <-- ${src}" )
    add_executable( ${exe} ${src} )
endforeach( src )

There are some utility functions in utilities.cmake, use include(utilities.cmake) to include, then use

print_include_directories() to print all included directories,
print_all_linked_libraries(your_exe_or_lib) to print all linked libs,
print_all_variables() to print all variables

Tip, use cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=YES .. to generate compile commands (a json file).

CMake's documentation is not for human. It really smells
Adapt to various standards is by no means easy, it's kind of brain fucking
