[Buildroot] Installed external gstreamer, enabled WebRTC and installed external libnice plugins to buildroot, however, libnice is missing

[Vered Kalef]

Hi
upgraded buildroot version to 2018.05.3, so, I'll have libnice 1.14 built
in .
I enabled it.
Restored the connection between webrtc and original libnice.
I saw that I should have the plugins nicesrc and nicesink (the plugins are
part of libnice associated with gstreamer).
Still I get that libnice is missing in the installation - libnice elements
are not available
I'm still missing an installation.
Regards,
Vered
