# Configure
#
# NOTE:
# - Option -DENABLE_FLTK=0 is used because we do not need GUI.
# - Option -DENABLE_MPEG_ENCODE=0 is used because we do not need to record MPEG 
#       movies.
# - Option -DENABLE_OCC=0 is used because we do not need CAD kernel and are not 
#       importing STEP/IGES files.
# - Option -DENABLE_TOUCHBAR=0 is used because we do not have GUI, therefore we 
#       do not need to support Apple Touch bar (does not affect compilation on 
#       Linux).
