I'm not totally certain I guess well what exactly you have done. There
is a WebRTC helper library and there is the plugin library, the two are
seperate. You should never have to link to the plugin library (or any
plugin library) on general setup. This is strictly limited to
Android/iOS with static builds.

What may happen is that the --prefix in your build don't match the
installation path, in which case you have to set some env to tell
GStreamer were to look (see gst-launch-1.0 man page / GST_PlUGIN_PATH).
