Hi, I'm attempting to use crane to build a bevy app. Unfortunately, it doesn't work as is (see https://github.com/bevyengine/bevy/blob/4bf647ff3b0ca7c8ca47496db9cfe03702328473/docs/linux_dependencies.md#nix) and requires a few extra libraries to be specified. The following wrapper works:

   runnable = pkgs.writeShellApplication {
            name = "runnable";
            text = "${default}/bin/repl-gui";
            runtimeEnv.LD_LIBRARY_PATH =
              with pkgs;
              lib.makeLibraryPath [
                libxkbcommon
                vulkan-loader
              ];
          };

I want to be able to directly patch the binary in order to avoid needing a wrapper script. Ideally adding this would work:

fixupPhase = ''
                patchelf --add-rpath ${
                  with pkgs; lib.makeLibraryPath [
                    libxkbcommon
                    vulkan-loader
                  ]
                } $out/bin/repl-gui
              '';

At the moment this gets run for the deps derivation though which is definitely not what we want:

       > Running phase: fixupPhase
       > patchelf: getting info about '/nix/store/rim753r2ivl6x8xykgyyjnih1fv4gqyp-repl-gui-deps-0.1.0/bin/repl-gui': No such file or directory
