方法一： 这个是很早以前的方法

需要设置两个文件： tasks.json 和 launch.json 

task 文件（ terminal -> config task）是设置编译器的参数设置

launch 文件(Debug -> add configuration)是负责调试相关参数设置

例子文件如下：

launch.json

{
    // 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": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build/main",
            "args": [],
            "stopAtEntry": true,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

task.json

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "CMake Debug and Make",
            "type": "shell",
            "options": {
                "cwd": "${workspaceRoot}/build"
            },
            "command": "cmake -DCMAKE_BUILD_TYPE=Debug .. && make",
            "group": "build",
            "presentation": {
                // Reveal the output only if unrecognized errors occur.
                "reveal": "silent"
            },
            // Use the standard MS compiler pattern to detect errors, warnings and infos
            "problemMatcher": [
                "$gcc"
            ]
        }
    ]
}

例子程序放到了这里，hello world示例程序，下载即可跑

方法二： 极力推荐，2023/03/01 更新此方法

1. 直接将带有cmakelist的工程，打开这个工程的folder，点开cmakelist文件， 按下ctr+shift+P

输入cmake

选择cmake： configure选项

 直接一键配好cmake，这样makefile就生成在cmake文件夹里

2. build

 点击下面的build按钮，直接编译成功

3. debug

点击步骤二的小爬虫，就可以直接打断点debug了

非常简单，你学费了吗？ 

不得不说vscode越做越强大了
