I tried pkgs.nvidia-texture-tools but the it did not work. I dont have any gpu I need nvtt to build 0ad. I was using a shell.nix to add packages and dependencies. I am attaching that here.

{pkgs ? import <nixpkgs> {}}:
pkgs.mkShell {
  name = "0ad-env";

  buildInputs = [
    pkgs.gcc11
    pkgs.llvmPackages_20.bintools

    pkgs.cmake
    pkgs.pkg-config
    pkgs.subversion
    pkgs.python3
    pkgs.boost
    pkgs.cargo
    pkgs.rustup

    pkgs.curl

  ];

  shellHook = ''
