The creation of the gstreamer-full library is closely tied to GStreamer build
system. The libnice plugin is not part of GStreamer project, but par of libnice
project. I think there would be some values to try and figure-out a way, but for
now, the build system is simply not aware of the existance of that plugin
(nothing is hardcoded, it's all done through meson).
