Debugger executable '/usr/local/bin/gdb' is not signed. As a result, debugging may not work properly

Debugger executable /usr/local/bin/gdb is not signed. As a result, debugging may not work properly in vscode in macOS Catalina 10.15.6.

I am providing the launch.json file for reference.

{
"version": "0.2.0",
"configurations": [
    {
        "name": "(lldb) Launch",
        "type": "cppdbg",
        "request": "launch",
        "program": "${workspaceRoot}/build/ghermite.mod",
        "miDebuggerPath": "/usr/local/bin/gdb",
        "args": [],
        "stopAtEntry": false,
        "cwd": "${workspaceRoot}",
        "externalConsole": false,
        "preLaunchTask": "build"
    }
  ]
}
