Looks like some files were moved from glib2 to a new package glib2-devel, specifically /usr/bin/glib-mkenums, so now the build fails with
gstreamer/subprojects/gst-plugins-bad/gst-libs/gst/interfaces/meson.build:5:20: ERROR: Dependency 'glib-2.0' tool variable 'glib_mkenums' contains erroneous value: '/usr/bin/glib-mkenums'
This is a distributor issue -- please report it to your glib-2.0 provider.
After manually installing glib2-devel the build worked, so you might want to add that to the dependencies.
