Describe the bug

cargo-tauri app can not be used to build appimage for tauri apps

Here are more explanations: https://github.com/tauri-apps/tauri/issues/8535

Steps To Reproduce

Steps to reproduce the behavior:

1. use the provided flake:
2. create a tauri app
3. https://github.com/tauri-apps/tauri/issues/8535
4. run tauri build -v

results in:

-- Running input plugin: gtk --
[gtk/stdout] Installing AppRun hook
[gtk/stderr] chmod: cannot access 'taskyon.AppDir/usr/lib64': No such file or directory
[gtk/stdout] Installing GLib schemas
[gtk/stderr] Package gio-2.0 was not found in the pkg-config search path.
[gtk/stderr] Perhaps you should add the directory containing `gio-2.0.pc'
[gtk/stderr] to the PKG_CONFIG_PATH environment variable
[gtk/stderr] No package 'gio-2.0' found
[gtk/stderr] cp: cannot stat '/usr/share/glib-2.0/schemas': No such file or directory

Expected behavior

It should work out-of-the-box

Hey thanks for reporting. Im wondering what we are doing wrong exactky. It could be just an env var that needs to be set or something. If you hear from upstream im interested!

hey, I have investigated a little further.

it seems that the missing https://nixos.wiki/wiki/Rust#Installation_via_rustup is part of the glib.dev package.

--> nix-locate --top-level /share/glib-2.0/schemas

--> I found this version here, configuring rust with rustup:

https://nixos.wiki/wiki/Rust#Installation_via_rustup

it sets some env variables and installes gib.dev. I tried several things with that, but still the same error.
