It would be good to wrap gnome-chess to include it's own share directory
in the XDG_DATA_DIRS environment variable. Without that, I can't just
run it [1], but when I set that variable correctly [2], it works :)

1:
→ /gnu/store/jv8jpq23iic13j7zdl8mdc30vcv508wh-gnome-chess-3.36.0/bin/gnome-chess

(gnome-chess:10039): GLib-GIO-ERROR **: 08:31:52.482: Settings schema 'org.gnome.Chess' is not installed

2:
→ XDG_DATA_DIRS="$XDG_DATA_DIRS:/gnu/store/jv8jpq23iic13j7zdl8mdc30vcv508wh-gnome-chess-3.36.0/share" /gnu/store/jv8jpq23iic13j7zdl8mdc30vcv508wh-gnome-chess-3.36.0/bin/gnome-chess


This wrapping is something that would automatically be done through the
glib-or-gtk-build-system, but maybe not automatically through the meson
build system.

Apart from the wrapping I mentioned above, this looks good to me :)

Thanks,

Chris
