flake: allow extra QT packages in dms-shell package

[LuckShiba]

This allows users to, optionally, add extra QT packages in dms-shell wrapper variables. This is useful for some QT packages some plugins may need, such as qtwebsockets in #1892.

Example usage:

{
  programs.dank-material-shell.package = dmsPkgs.dms-shell.override {
    extraQtPackages = with pkgs.kdePackages; [ qtwebsockets ];
  };
}

Mhh.. Somehow with this approach, the HomeAssistant plugin again reports "Missing dependency". Not sure if this because I was using the stable version before.

UPDATE: No, was using the same DMS / Quickshell version of course. Will have a look what I am doing wrong.

@djmaze, have you used the kdePackages.qtwebsockets and restarted your DMS after rebuilding? I just tested on my system, and adding qtwebsockets the same way as in the example in the description here got rid of the "Missing dependency" warning 😕

Run grep qtwebsockets $(which dms) and tell me if it has the qtwebsockets paths on it, it should have.

[djmaze]

Yeah, it is in there, I already checked that before. Of course I also restarted dms. When switching back to my branch, it works again.

I realized though that with the setup from my branch it is qtwebsockets-6.10.2 while with the config I am using your branch with it is qtwebsockets-6.10.1. Though I tried to use nixos-unstable same as in the dms flake.

But I have to admit I am not a NixOS expert, so trying to find my way through this. My config inside looks like this (I have a flake-based NixOS setup):

  programs.dank-material-shell = {
    enable = true;
    enableSystemMonitoring = true;
    package = dms.packages.x86_64-linux.dms-shell.override {
      extraQtPackages = with nixos-unstable.kdePackages; [ qtwebsockets ];
    };
    dgop.package = pkgs-unstable.dgop;
  };

I probably need to find a way to fix this myself.
