CMake build fail: hard-coded to use static version of libmfx, although MediaSDK provides only shared one

[eero-t]

Setup:

• Ubuntu 18.04
• Latest Open Source MediaSDK built from Git
• Git version of gstreamer-media-SDK

Problem:

• Build files are hard-coded to use static version of libmfx, although Open Source Media SDK version build provides only shared one

This patch fixed it for CMake:
