对Lib项目的统一输出路径以下时解决方案：
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY
${CMAKE_BINARY_DIR}/Lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY
${CMAKE_BINARY_DIR}/Lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY
${CMAKE_BINARY_DIR}/Bin)
以上三行命令要写在根（root）CmakeLists.txt的里面.

以下是（root）CmakeLists.txt的代码:

TIPS：add_subdirectory命令执行中，就直接执行子目录下的CmakeLists.txt里面的代码了
