Script might well override a static map, but can't risk it not doing it, and preview completely failing. Better to just not try it for static maps. Some script cfg might help. Could also avoid unnnecessary preview regenerations even if the script was doing nothing at all.

# 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
