Re: [Libguestfs] [p2v PATCH 1/2] require GLIB2 >= 2.56 and GTK3 >= 3.22; enhance API compatibility

For further simplifying virt-p2v's GTK API usage, require the GLIB2 and GTK3 versions that RHEL7 provides. The MIN_REQUIRED=<version> macros elicit warnings if we use an API that was already deprecated in said version of the given library. The MAX_ALLOWED=<version> macros make sure we don't unwittingly use an API that was introduced after our required minimum version. (GDK is a layer below GTK, so using the GDK_VERSION_* macros ensures both GDK and GTK API compatibility.) Suggested-by: Richard W.M. Jones <rjones(a)redhat.com&gt; Suggested-by: Daniel P.
