commit 62c5baa9f89cf8c7e2f43f688b1a4991c9b55c08
Author: Steffen Hau <steffen@hauihau.de>
Date:   Mon Mar 11 22:31:11 2024 +0100

    make support for glib/gio, gtk and atk/atspi configurable
    - enabling screencast leads to -DWEBRTC_USE_GIO which leads to compile errors if use_gio=false
    - use_atk requires use_glib
    - x11-libs/(cairo,gdk-pixbuf,pango) is not needed for a pure Qt build
