前几天给部门同事做Linux测试环境搭建的培训，为了给部门同事开拓眼界，所以将CMake构建工具作为拓展内容加到了培训中，并且一时兴起，将公司的几个项目全部加入了CMake构建内容，在改造过程中，一些过程记录如下。

1、一个简单的CMakeLists.txt文件

PROJECT（PROJECTNAME）

CMAKE_MINIMUM_REQUIRED(VERSION 2.8）#Set project root directory.SET(PROJECT_ROOT_DIRECTORY "/home/ubt/cmakepro")#Set source lists. SET(SRC_LIST all.c all.h ...)#Include header files directory.INCLUDE_DIRECTORIES(../../inc inc .) # Include link library pathLINK_DIRECTORIES("${PROJECT_ROOT_DIRECTORY}/lib")#Create exectuable file according source list.ADD_EXECUTABLE(TargetName ${SRC_LIST})#Set link library.TARGET_LINK_LIBRARIES(TargetName cli fastdb sqlite3 config m pthread rt)

2、多级目录的扩展

1)、项目根目录CMakeLists.txt文件内容：

PROJECT(PROJECTNAME)CMAKE_MINIMUM_REQUIRED(VERSION 2.8)SET(PROJECT_ROOT_DIRECTORY "/home/ubnt/cmakepro")MESSAGE(STATUS "Project root directory:" ${PROJECT_ROOT_DIRECTORY})ADD_SUBDIRECTORY(src/moduleA)ADD_SUBDIRECTORY(src/moduleB)ADD_SUBDIRECTORY(src/moduleC/moduleCA)ADD_SUBDIRECTORY(src/moduleC/moduleCB)MESSAGE(STATUS "Project dir :" ${PROJECT_BINARY_DIR})

2）、项目子目录下的CMakeLists.txt内容：

SET(SRC_LIST moduleA.cpp moduleA.h ...INCLUDE_DIRECTORIES(${PROJECT_ROOT_DIRECTORY}/inc ${PROJECT_ROOT_DIRECTORY}/inc/sqlite3 ${PROJECT_ROOT_DIRECTORY}/inc/fastdb${CMAKE_CURRENT_SOURCE_DIR})LINK_DIRECTORIES(${PROJECT_ROOT_DIRECTORY}/lib )SET(EXECUTABLE_OUTPUT_PATH ${PROJECT_BINARY_DIR}/program/bin)ADD_EXECUTABLE(mouduleA ${SRC_LIST})TARGET_LINK_LIBRARIES(mouduleA  fastdb sqlite3 rt)

同样的完成B、C模块下的CMakeLists.txt 文件。

3、指定编译器的CMakeLists.txt文件示例

1)、项目目录下CMakeLists.txt的内容：

PROJECT(PROJECTNAME)CMAKE_MINIMUM_REQUIRED(VERSION 2.8)SET(PROJECT_ROOT_DIRECTORY "/home/ubnt/cmakepro")MESSAGE(STATUS "Project root directory:" ${PROJECT_ROOT_DIRECTORY})SET(CMAKE_SYSTEM_NAME Linux)SET(CMAKE_FIND_ROOT_PATH "/home/ubt/toolchain/arm-2008q1/arm-none-linux-gnueabi/libc/lib")SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)SET(CMAKE_C_COMPILER "/home/ubt/toolchain/arm-2008q1/bin/arm-none-linux-gnueabi-gcc")SET(CMAKE_CXX_COMPILER "/home/ubt/toolchain/arm-2008q1/bin/arm-none-linux-gnueabi-g++")ADD_SUBDIRECTORY(src/moduleA)ADD_SUBDIRECTORY(src/moduleB)ADD_SUBDIRECTORY(src/moduleC/moduleCA)ADD_SUBDIRECTORY(src/moduleC/moduleCB)MESSAGE(STATUS "Project dir :" ${PROJECT_BINARY_DIR})

2）、子目录下的CMakeLists.txt ：

SET(SRC_LIST moduleA.cpp moduleA.h ...)INCLUDE_DIRECTORIES(${PROJECT_ROOT_DIRECTORY}/inc ${PROJECT_ROOT_DIRECTORY}/inc/sqlite3 ${PROJECT_ROOT_DIRECTORY}/inc/fastdb${CMAKE_CURRENT_SOURCE_DIR})LINK_DIRECTORIES(${PROJECT_ROOT_DIRECTORY}/lib )#Set Executable output pathSET(EXECUTABLE_OUTPUT_PATH ${PROJECT_BINARY_DIR}/program/bin)ADD_EXECUTABLE(mouduleA ${SRC_LIST})TARGET_LINK_LIBRARIES(mouduleA  fastdb sqlite3 rt)

4、加入安装操作的CMakeLists.txt

INSTALL(FILES ModuleC/xx ....DESTINATION ${PROJECT_BINARY_DIR}/program/etc)INSTALL(FILES ModuleB/xxx ...DESTINATION ${PROJECT_BINARY_DIR}/program/etcPERMISSIONS OWNER_READ OWNER_WRITE OWNER_EXECUTEGROUP_READ GROUP_EXECUTE WORLD_READ WORLD_EXECUTE )INSTALL(DIRECTORY init.d DESTINATION ${PROJECT_BINARY_DIR}/program/etcPATTERN "init.d/*"PATTERN ".svn" EXCLUDEPERMISSIONS OWNER_READ OWNER_WRITE OWNER_EXECUTEGROUP_READ GROUP_EXECUTE WORLD_READ WORLD_EXECUTE )
