I'm trying to package https://github.com/zbanks/radiance

{
  lib,
  rustPlatform,
  fetchFromGitHub,
  pkg-config,
  # autoPatchelfHook,
  libxkbcommon,
  mpv-unwrapped,
  vulkan-loader,
  stdenv,
  darwin,
  alsa-lib,
  wayland,
  xorg,
  yt-dlp,
}:

rustPlatform.buildRustPackage rec {
  pname = "radiance";
  version = "0.7.0";

  src = fetchFromGitHub {
    owner = "zbanks";
    repo = "radiance";
    rev = version;
    hash = "sha256-itBBUKwJAWfLPXZaJ65UbabDoZUUZtZm8bGAU0joVsQ=";
  };

  cargoLock.lockFile = ./Cargo.lock;

  postPatch = ''
    ln -s ${./Cargo.lock} Cargo.lock
  '';

  nativeBuildInputs = [
    pkg-config
    # autoPatchelfHook
  ];

  buildInputs =
    [
      mpv-unwrapped
      vulkan-loader
      libxkbcommon
    ]
    ++ lib.optionals stdenv.isLinux [
      alsa-lib
      wayland

      # X11 / XCB stack (required by winit + xkbcommon-dl)
      xorg.libX11

  propagatedUserEnvPkgs = [
    yt-dlp
  ];

  # Floating-point exact-equality bugs upstream
  doCheck = false;

  meta = {
    description = "Video art software for VJs";
    homepage = "https://github.com/zbanks/radiance";
    license = lib.licenses.mit;
    maintainers = with lib.maintainers; [ magnetophon ];
    mainProgram = "radiance";
  };
}

When I run it, I get:

❯ radiance

Any ideas on how to fix that?

Thanks.
Like this?

  preFixup = lib.optionalString stdenv.hostPlatform.isLinux ''
    patchelf \
      --set-rpath "${lib.makeLibraryPath buildInputs}:$out/lib" \
      $out/bin/radiance
  '';

I still get:
