利用vscode在windows下gcc编译开发

1. 安装cmake

https://cmake.org/download/

2. 安装cygwin

3. 在vscode中安装CMake Tools插件

https://marketplace.visualstudio.com/items?itemName=ms-vscode.cmake-tools

4. 实际操练经验

如果使用CMake quickstart 生成的项目需要 删除 除了 CMakeLists.txt 和 main.cpp 外的所有东西，然后新建build目录，在build目录下执行

build> cmake -G "Unix Makefiles" ../

然后在build目录下make

build> make
