# Note about the gst-plugin-base dep: The build system queries for it,
# but doesn't link it for some reason?  Either way - probably best to
# depend on it anyway.
# Note about the wayland dep: Appears to be only required for the OpenGL
# canvas, and it seems impossible to disable the X dependency, unless
# I'm missing something.  This is an automagic header dep, though.
