Description

I am building various software in an environment where all headers/etc are split per package, which allows me to find that parole should check for the following packages and use their cflags/ldflags/etc.

plugins/mpris2/mpris2-provider.c:29:10: fatal error: gst/tag/tag.h: No such file or directory

This is solved by importing gstreamer-tag-1.0 cflags. I see configure goes through a number of pkg-config, gstreamer-tag-1.0 should be one of these.
