cz-Hickson Cursors

I am currently testing the cz-Hickson cursor set

{
  cz-Hickson-cursors = pkgs.stdenvNoCC.mkDerivation rec {
    pname = "cz-Hickson-cursors";
    version = "3.0";
    src = pkgs.fetchFromGitHub {
      owner = "charakterziffer";
      repo = "cursor-toolbox";
      rev = "ec5e7e582be059996c0405070494ae9ed7834d4d";
      hash = "sha256-jJvtV0+Ytnu/gLyvSX+/mqZeunnN5PCDypYRSAc+jJw=";
    };
 
    strictDeps = true;
 
    nativeBuildInputs = with pkgs; [
      xorg.xcursorgen
    ];
    prePatch = ''
      substituteInPlace make.sh --replace-fail "'My Cursor Theme'" '"$1"'
    '';
    buildPhase = ''
      cd more-themes/cz-Hickson
      ln -snf pngs-black pngs
      ../../make.sh cz-Hickson-black
      ln -snf pngs-white pngs
      ../../make.sh cz-Hickson-white
    '';
    installPhase = ''
      mkdir -p $out/share/icons
      cp -r cz-Hickson-* $out/share/icons
    '';
  };
}
