环境搭建

• demo文件目录

[sxy@DESKTOP-SXY gtest-demo_new]$ tree 
.
└── gtest-demo
    ├── cmake                    #测试环境构建
    │   ├── googletest.cmake
    │   └── googletest-download.cmake
    ├── CMakeLists.txt

• cmake理解

- GNUInstallDirs:gnu安装目录
- include：获取某一文件中的cmake代码
- macro(<name> [arg1 [arg2 [arg3 ...]]])：定义一个宏，后面是宏名和参数
- configure_file：复制input文件中的内容到output,复制过程中替换某些值
- execute_process：执行进程，指定WORKING_DIRECTORY后在该子目录下执行命令
- add_library

更改demo的目录结构

root_dir
  - lib
    - sublib0
    - sublib2
  - src 
    - test_module
    - application
  - doc 
  - gtest_demo
  - build 
    - scripts to build application
  - scripts to all
