Building fails on openSUSE Tumbleweed - Patch attached

Building the current master fails on openSUSE Tumbleweed, as the ffmpeg-headers are not found. Sorry, I do not have the error message anymore as I fixed it with the following patch:

Review FindFFMPEG.cmake and the attached FFmpeg discovery changes; first reproduce the openSUSE Tumbleweed build failure against the current master. Done means confirming that the reported FFmpeg header and library detection issue is resolved and that the project builds successfully with the supplied changes.
