将路径D:\msys64\mingw64\bin和D:\msys64\usr\bin添加到PATH环境变量。
然后通过Command Prompt确认关键命令：

以上即可通过快捷键F5调试当前活动的单源文件。特别注意，源文件必须为当前编辑焦点。

多文件工程

目前笔者只验证了make。对于cmake，创建生成器cmake -G "MSYS Makefiles" ..执行不成功。多次尝试后决定暂时放弃，如有读者等帮忙指出办法。不胜感激。注：笔者已自行找到答案。请参考CMAKE章节。

tasks.json

    // See https://go.microsoft.com/fwlink/?LinkId=733558

            "command": "make",
            "args": [
                "-j1"
            ],
            "options": {
                "cwd": "${workspaceRoot}"
            },
            "group": {
                "kind": "build",
                "isDefault": true

                "clear": true
            }
        }
    ]
}

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": "CppDebug",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceRoot}\\Effendi.exe",
            "args": [
                "EDID",
                "-i",
                "resource/DENON-AVR-X1600H.edid.txt"
            ],
            "stopAtEntry": false,
            "cwd": "${workspaceRoot}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "D:\\msys64\\mingw64\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "build"
        }
    ]
}

以上即可通过快捷键F5调试当前工程。特别注意，编译器的-g选项保存在Makefile文件。可以通过tasks.json传递make参数关闭或者打开（默认打开）。另外，运行时参数目前只会通过launch.json，不能像正常gdb那样先加载程序，set args然后再运行。如有读者等帮忙指出办法，可以运行时set args。不胜感激。

CMAKE

激活cmake的洪荒之力的关键点是workspace将默认shell设置成bash。笔记因为考虑到其他项目IAR工程需要默认shell设置成Command Prompt，所以一直不能修改全局shell。经，仔细阅读VSCODE的官网说明后，终于找到了Workspace设置独立shell的办法。终于还是如愿了。愿所有码农知所求，得所愿。
