Say you pick 3.22 as your official min and check this with pkg-config in configure, then you can further define GDK_VERSION_MIN_REQUIRED=GDK_VERSION_3_22 GDK_VERSION_MAX_ALLOWED=GDK_VERSION_3_22 The former will give you warnings if you use any API that was already deprecated in 3.22 - this is something that should be re-written to use the recommended modern alternative API.

The latter will give you warnings if you use any API that was introduced after 3.22 - this is to prevent you accidentally introducing usage of APIs newer than your min version The same exists for glib via GLIB_VERSION_MIN_REQUIRED/MAX_ALLOWED.
