Pastebins with the verbose cmake output:
WITH -lavutil: http://pastebin.com/EmFXG8Dc
WITHOUT -lavutil: http://pastebin.com/vs18fdqj

I don't really understand why this isn't working, because the linking order
seems correct. I do see that the full path of the shared library objects
that ROS uses normally are written out completely. Do I need to create a
ffmpeg package finding module .cmake file to make the .so full path appear?

Thanks.
