+Subject: [PATCH] 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
