How can I add an external C library in Visual Studio Code?

I read How can I include a needed C library using GCC? and tried:

{
"version": "2.0.0",
"tasks": [
    {
        "type": "shell",
        "label": "build",
        "command": "C:\\MinGW\\bin\\gcc.exe",
        "args": [
            "-g",
            "${file}",
            "-o",
            "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "-L \\C:\\MinGW\\lib",
            "-l libws2_32.a"
        ],
        "options": {
            "cwd": "C:\\MinGW\\bin"
        },
        "problemMatcher": [
            "$gcc"
        ]
    }
]

But I got

c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../../mingw32/bin/ld.exe: cannot find -l libws2_32.a
collect2.exe: error: ld returned 1 exit status

And I installed GCC in folder C:\MinGW.

https://gcc.gnu.org/onlinedocs/gcc/Link-Options.html#index-Libraries "-l*library* [...] Static libraries are archives of object files, and have file names like lib*library*.a." I.e. `-lws2_32` looks for a file called `libws2_32.a`. – melpomene Jun 19 '19 at 05:42
What is that format? [JSON](https://en.wikipedia.org/wiki/JSON)? Where did you put it? In file *settings.json*? – Peter Mortensen Nov 06 '22 at 02:44
