48.1 is gtk4 version.

Linuxmint 22.2 patched libadwaita to support mint-themes. However, libadwaita on ArchLinux isn't patched.

So use libadwaita-without-adwaita to support mint themes. Or just use 41.2 version by git checkout.

This newest version only add support gnome-online-accounts-gtk. This package provided by Arch requires gnome-control-center to manage online accounts.

If you don't need this, just use the version in Arch official repository.
