CMakeList使用总结

一、cmake功能介绍

二、CMakeLists编写介绍

$ENV{ 
   系统变量} $ENV{ 
   PATH} 

5.指定可执行文件生成路径:

SET(EXECUTABLE_OUTPUT_PATH "xxx/bin") 

6.指定输出动态库的目录位置:

SET(LIBRARY_OUTPUT_PATH "xxx/lib") 

7.获取源代码、头文件路径：

FILE(GLOB SRC_LIST "${PROJECT_SOURCE_DIR}/src/*.cpp") FILE(GLOB HEAD_LIST "${PROJECT_SOURCE_DIR}/include/*.h") 

8.添加头文件路径:

include_directories("${PROJECT_SOURCE_DIR}/include") 

9.添加链接库路径:

link_directories("${PROJECT_SOURCE_DIR}/lib") 

10.添加生成可执行文件:

add_executable(${PROJECT_NAME} ${SRC_LIST} ${HEAD_LIST}) 

11.链接库名:

target_link_libraries(${PROJECT_NAME} ${LIB_NAME}) 

12.添加生成动态库或静态库: 不写默认静态库

add_library(${LIB_NAME} SHARED ${PROJECT_SOURCE_DIR}/third/test.cpp) add_library(${LIB_NAME}_static STATIC ${PROJECT_SOURCE_DIR}/third/test.cpp) 

13.静态库的输出名称：

set_target_properties(${LIB_NAME}_static PROPERTIES OUTPUT_NAME ${LIB_NAME}) 

14.设置预处理宏开关 开启:

option(USE_TEST "option for test" ON) 

15.配置一个头文件用于传递一些CMake中的配置到源代码中

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

 install(TARGETS myrun mylib mystaticlib RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR} LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR} ARCHIVE DESTINATION ${CMAKE_INSTALL_LIBDIR} ) 

16.2安装整个目录

 install(DIRECTORY ${OUT_PATH} DESTINATION ${PROJECT_SOURCE_DIR}) install(DIRECTORY ${OUT_PATH} DESTINATION ${PROJECT_SOURCE_DIR} PATTERN "${EXE_NAME}" PERMISSIONS OWNER_EXECUTE OWNER_READ GROUP_EXECUTE GROUP_READ WORLD_EXECUTE WORLD_READ) 

16.3安装文件

 install(FILES "${PROJECT_BINARY_DIR}/bin/${EXE_NAME}" DESTINATION "${PROJECT_SOURCE_DIR}/bin" PATTERN "${EXE_NAME}" PERMISSIONS OWNER_EXECUTE OWNER_READ GROUP_EXECUTE GROUP_READ WORLD_EXECUTE WORLD_READ) install(FILES "${PROJECT_BINARY_DIR}/lib/lib${LIB_NAME}.a" DESTINATION "${PROJECT_SOURCE_DIR}/lib") install(FILES "${PROJECT_BINARY_DIR}/lib/lib${LIB_NAME}.so" DESTINATION "${PROJECT_SOURCE_DIR}/lib") 

三、CMakeList构建Qt工程

1.设置开启MOC UIC RCC编译器

set(CMAKE_INCLUDE_CURRENT_DIR ON) set(CMAKE_AUTOMOC ON) set(CMAKE_AUTOUIC ON) set(CMAKE_AUTORCC ON) set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC") 

2.添加qt模块 添加头文件路径 依赖库路径 库名称 Findxxx.cmake xxxConfig.cmake

find_package(Qt5Widgets CONFIG REQUIRED) target_link_libraries(${ 
   PROJECT_NAME} Qt5::Widgets) <NAME>_FOUND <NAME>_INCLUDE_DIRS or <NAME>_INCLUDES <NAME>_LIBRARIE or <NAME>_LIBRARIES or <NAME>_LIBS <NAME>_DEFINITIONS =================================== find_package(PkgConfig) pkg_search_module(Qt5Widgets REQUIRED Qt5Widgets) target_link_libraries(${ 
   PROJECT_NAME} ${ 
   Qt5Widgets_LIBRARIES}) ===================================================== (pkg-config xxx a.默认usr/bin/*.pc b.读取环境变量PKG_CONFIG_PATH c.pkg-config --variable pc_path pkg-config ) (动态库 a.LD_LIBRARY_PATH b./etc/ld.so.conf　c./lib or /usr/lib) 

四、CMakeList添加第三方库

1.编写编译安装脚本 命名为uchartdet_install.sh

cd libiconv-1.16 path=”`pwd`/../lib” #生成路径自己指定 ./configure --enable-extra-encodings --prefix=$path --enable-static --disable-shared make make install 

2.在第三方库third目录下编写CMakeList.txt

execute_process(COMMAND bash "${CMAKE_CURRENT_SOURCE_DIR}/uchartdet_install.sh" WORKING_DIRECTORY ${ 
   CMAKE_CURRENT_SOURCE_DIR}) 

3.在上级CMakeList.txt添加add_subdirectory(third)

   HEADS} ${ 
   SRCS} ) #引用路径,包含编译给定目标时需要使用的目录 target_include_directories(${
