1. 下载vscode

2. 安装c++插件

参考：C++ programming with Visual Studio Code

3. 安装llvm，可以使用brew安装

4. 配置llvm到系统环境变量中

5. 编写c++代码

6. 编写CMakeLists.txt文件（前提安装cmake）

cmake_minimum_required(VERSION 3.5)project(vscode_cmake_debug)# 设置可执行文件的输出路径
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)# 重点
set(CMAKE_BUILD_TYPE "Debug")add_executable(main src/main.cpp)

7. 生成vscode中c++的智能提示文件c_cpp_properties.json

可参考：https://code.visualstudio.com/docs/cpp/config-clang-mac

{"configurations": [{"name": "Mac","includePath": ["${workspaceFolder}/**"],"defines": [],"macFrameworkPath": ["/Library/Developer/CommandLineTools/SDKs/MacOSX13.sdk/System/Library/Frameworks"],"compilerPath": "/opt/homebrew/opt/llvm/bin/clang","intelliSenseMode": "macos-clang-arm64"}],"version": 4
}

8. 生成vscode debug文件launch.json

具体可参考：Configure VS Code for Clang/LLVM on macOS

{// Use IntelliSense to learn about possible attributes.// Hover to view descriptions of existing attributes.// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387"version": "0.2.0","configurations": [{"name": "Debug","type": "lldb","request": "launch",            "program": "${workspaceFolder}/cmake_debug/bin/main","args": [],"stopAtEntry": false,"cwd": "${workspaceFolder}","environment": [],"externalConsole": false,"MIMode": "gdb","setupCommands": [{"description": "Enable pretty-printing for gdb","text": "-enable-pretty-printing","ignoreFailures": true}],//"preLaunchTask": "C/C++: g++ build active file",//"miDebuggerPath": "lldb的路径"}]
}

其中部分字段配置可参考：

https://code.visualstudio.com/docs/editor/variables-reference

和Configure launch.json for C/C++ debugging in Visual Studio Code

因为已经采用cmake编译，所以launch中的preLaunchTask可以不用关联task了
