VSCODE Debug C++_vscode c++ debug

1. CMake项目编译为Debug版本、

 set(CMAKE_BUILD_TYPE "Debug")
1

2. 编辑launch.json
   1）快捷键ctrl +shift + d,进入调窗口，点击设置launch.json（齿轮样子）,在下拉菜单中选择 C++ (GDB/LLDB),此时会在刚刚创建的工程文件夹下的.vscode文件夹下创建一个launch.json文件（.vscode是隐藏文件，如果没有显示出来使用快捷键ctrl + h即可显示，再次按下ctrl + h即可隐藏）
   2）打开launch.json，配置参数，到此环境参数配置完成就可以执行F5运行debug,同时可以再每行语句前打断点调试（后面有在断点调试时可能会报错的处理）
   launch.json文件
