c - How to debug in vscode already compiled executable?

Question

When trying to debug in vscode, the vscode generate launch.json config file. When I try to debug, it first tries to compile the source and then debug the exe. I would like to just debug already compiled executable (compiled with gcc -g option).

The json file is:

{
    // 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": "gcc-10 - Build and debug active file",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [
                "-pthread",
                "common.c"
            ],
            "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++: gcc-10 build active file",
            "miDebuggerPath": "/usr/bin/gdb"
        }
    ]
}

Can I make somehow the vsode to not compile but just debug with already compiled source to "program":"${fileDirname}/${fileBasenameNoExtension}", I have compiled to the very same name - no extension in current directory, as the property suggest. So how to make vscode to take this executable as its debug file?
