build: raise an error if pkg is not found Changed FFmpeg, PCSC and PulseAudio cmake find to raise an error if an required package was not found.

# - Try to find FFmpeg
# Using Pkg-config if available for path
#
# FFMPEG_FOUND - all required ffmpeg components found on system
# FFMPEG_INCLUDE_DIRS - combined include directories
# FFMPEG_LIBRARIES - combined libraries to link
build: check libavcodec api version If pkg-config is available libavcodec api version is checked and cmake fails if the required version isn't available. In case pkg-config isn't available a notification message with the required version is printed. This fixes/prevents #740.
