# Find ffmpeg/libav libraries (libavcodec, libavformat and libavutil)
# Once done this will define
#
#  LIBAV_FOUND             - system has libavcodec, libavformat, libavutil
#  LIBAV_INCLUDE_DIR       - libav include directories
#  LIBAV_LIBRARIES         - libav libraries (libavcodec, libavformat, libavutil)
#
#  LIBAVCODEC_LIBRARY      - libavcodec library
#  LIBAVCODEC_INCLUDE_DIR  - libavcodec include directory
#  LIBAVFORMAT_LIBRARY     - libavformat library
#  LIBAVUTIL_LIBRARY       - libavutil library
