gstreamermm Gst::ElementInterfaced and Gst::XOverlay cannot be resolved

[pjsanfil]

I tried using VideoOverlay and then using   set_window_handle(XID);
and that compiled but did not work. Once I ran the program the default
behavior of creating a new window to put the video stream in occurred. The
documentation saying to use XOverlay is in the VideoOverlay class
documentation.

Thanks,
Paul
