cmake学习

1、一个简单的cmakelist：

project(LeetCode)

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fprofile-arcs -ftest-coverage")

SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fprofile-arcs -ftest-coverage")

SET(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -fprofile-arcs -ftest-coverage -lgcov")

file(GLOB_RECURSE SRC_FILES

${CMAKE_CURRENT_LIST_DIR}/lib/*/*.c

${CMAKE_CURRENT_LIST_DIR}/lib/*/*.cc

${CMAKE_CURRENT_LIST_DIR}/lib/*/*.cpp

${CMAKE_CURRENT_LIST_DIR}/lib/*/*.h

${CMAKE_CURRENT_LIST_DIR}/lib/src/*.c

${CMAKE_CURRENT_LIST_DIR}/lib/src/*.cc

${CMAKE_CURRENT_LIST_DIR}/lib/src/*.cpp

${CMAKE_CURRENT_LIST_DIR}/lib/include/*.h

)

#添加头文件搜索路径，包头文件时方便

include_directories(

${CMAKE_CURRENT_LIST_DIR}/lib/include/

)

#生成库文件

add_library(static_${PROJECT_NAME} ${SRC_FILES} )

file(GLOB_RECURSE EXE_SRC_FILES

${CMAKE_CURRENT_LIST_DIR}/exe/src/*.c

${CMAKE_CURRENT_LIST_DIR}/exe/src/*.cc

${CMAKE_CURRENT_LIST_DIR}/exe/src/*.cpp

${CMAKE_CURRENT_LIST_DIR}/exe/include/*.h

)

#生成可执行文件

add_executable(${PROJECT_NAME} ${EXE_SRC_FILES})

#规定生成的依赖关系

add_dependencies(${PROJECT_NAME} static_${PROJECT_NAME})

#链接库文件，link_libraries用在add_executable之前，target_link_libraries用在add_executable之后

target_link_libraries(${PROJECT_NAME} static_${PROJECT_NAME})

if(UNIX)

target_link_libraries(${PROJECT_NAME} pthread)

endif()

set(PKG_GTEST gtest)

#获取完整的文件名

get_filename_component(PKG_GTEST_DIR "${CMAKE_CURRENT_LIST_DIR}/3rdparty/gtest-1.7.0" ABSOLUTE CACHE)

get_filename_component(PKG_GTEST_INCLUDE_DIR "${PKG_GTEST_DIR}/include" ABSOLUTE CACHE)

#把一个项目分割成几个范围有限的CMakeLists.txt文件，这些文件将使用add_subdirectory命令进行处理。分模块处理！！

add_subdirectory(${PKG_GTEST_DIR} ${CMAKE_CURRENT_BINARY_DIR}/${PKG_GTEST})

file(GLOB_RECURSE TEST_SRC_FILES

${CMAKE_CURRENT_LIST_DIR}/test/ft/*.c

${CMAKE_CURRENT_LIST_DIR}/test/ft/*.cc

${CMAKE_CURRENT_LIST_DIR}/test/ft/*.cpp

${CMAKE_CURRENT_LIST_DIR}/test/ft/*.h

${CMAKE_CURRENT_LIST_DIR}/test/src/*.c

${CMAKE_CURRENT_LIST_DIR}/test/src/*.cc

${CMAKE_CURRENT_LIST_DIR}/test/src/*.cpp

${CMAKE_CURRENT_LIST_DIR}/test/include/*.h

)

include_directories(

${CMAKE_CURRENT_LIST_DIR}/test/*/

${PKG_GTEST_INCLUDE_DIR}

)

add_executable(test_${PROJECT_NAME} ${TEST_SRC_FILES})

add_dependencies(test_${PROJECT_NAME} static_${PROJECT_NAME} ${PKG_GTEST})

target_link_libraries(test_${PROJECT_NAME} static_${PROJECT_NAME} ${PKG_GTEST})

if(UNIX)

target_link_libraries(test_${PROJECT_NAME} pthread)

endif()

#为当前及其下级目录打开测试功能??不懂具体含义

enable_testing()

add_custom_target(build_and_test

${CMAKE_CTEST_COMMAND} -V -C Debug

)

add_test(NAME ${PROJECT_NAME}

COMMAND test_${PROJECT_NAME}

)

add_dependencies(build_and_test test_${PROJECT_NAME} ${PROJECT_NAME})

 

 

2、目录架构：

 

 3、

 

 

 

# Glob all sources file inside directory ${DIRECTORY} file(GLOB_RECURSE TMP_FILES ${DIRECTORY}/*.h ${DIRECTORY}/*.cpp ${DIRECTORY}/*.c ) foreach(f ${TMP_FILES}) # Get the path of the file relative to ${DIRECTORY},# then alter it (not compulsory) file(RELATIVE_PATH SRCGR ${DIRECTORY}${f}) set(SRCGR "Something/${SRCGR}") # Extract the folder, ie remove the filename part string(REGEX REPLACE "(.*)(/[^/]*)$""\\1" SRCGR ${SRCGR}) # Source_group expects \\ (double antislash), not / (slash) string(REPLACE / \\ SRCGR ${SRCGR}) source_group("${SRCGR}" FILES ${f}) endforeach()
