Hi Laurentiu,
  Thanks for looking into this. As EMGD is closed source, we will not be able to look into it's sources. The best we can do is reverse engineering what you are already doing.  I understand it is hard to get it perfect from this way. But I guess we can get something working at least. And improve it as we go forward.

BTW I am also pinging the EMGD team who develops the EMGD packages, to start looking into these pkgconfig issues. If we can get some pkgconfig files from them, then we can avoid all this guess work. But I am not expecting anything from them quickly.
