CMakeList DLC速通手脚架

语法糖

受够了重复add_executable带来的键盘磨损？受够了add_subdirectory眼花缭乱？

此文摘录一些好用的Cmake函数，以用于项目构建。

   	set(${DIRNAME} ${TMP})
endmacro(GET_DIR_NAME DIRNAME)

GET_DIR_NAME(DIRNAME)

macro(ADD_ALL_SUBDIR)
    file(GLOB children RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} ${CMAKE_CURRENT_SOURCE_DIR}/*)
    set(dirlist "")
    foreach(child ${children})
        if(IS_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}/${child})
            if(${child} STREQUAL "CMakeFiles")
            else(${child})
                LIST(APPEND dirlist ${child})
            endif()
        endif()
    endforeach()
    foreach(subdir ${dirlist})
        add_subdirectory(${subdir})
    endforeach()
endmacro(ADD_ALL_SUBDIR)

顾名思义，不用再重复add_subdirectory了。

### 在子文件夹中创建CMakeLists.txt进行编辑
set(MODE "LIB")
#项目名，默认为目录名
GET_DIR_NAME(DIRNAME)
set(TARGET_NAME ${DIRNAME})
#多个源文件用 [空格] 分隔
#如：set(STR_TARGET_SOURCES "main.cpp src_2.cpp")
set(STR_TARGET_SOURCES "main.cpp ${CMAKE_SOURCE_DIR}/include/lib.h")
#多个库文件用 [空格] 分隔，如果为空，就输入[一个空格]
#如：set(STR_TARGET_LIBS "lib1.lib lib2.lib")
set(STR_TARGET_LIBS " ")

SETUP_PROJECT(${MODE} ${TARGET_NAME} ${STR_TARGET_SOURCES} ${STR_TARGET_LIBS})
