+From 10707f437f2fc3632067c6a0efa4432f7ebaf362 Mon Sep 17 00:00:00 2001
+From: Sebastian Dröge <sebastian at centricular.com>
+Date: Fri, 13 Dec 2019 10:46:20 +0200
+Subject: [PATCH] backport of "fix build with Python 3.8 by also checking for
+ python-3.X-embed.pc"
+
+Since Python 3.8 the normal checks don't include the Python libraries
+anymore and linking of the gst-python module would fail.
+
+See also https://github.com/mesonbuild/meson/issues/5629
+
+Fixes https://gitlab.freedesktop.org/gstreamer/gst-python/issues/28
+
