# What to put in your own Makefile:
#
# MODULEID=name_of_the_library (e.g. MODULEID=OVIMExample => OVIMExample.dylib)
# DATA=data_files_to_be_copied
# SOURCES=source_files      (without .c .cpp .m .mm extensions)
# EXTRA_GOALS=extra_goals   (put the extra target names here)
# EXTRA_CLEAN=other_files_to_be_cleaned
# HAS_VARIANTS=variant_names
#
# Then, in the end, insert a line "include ../Mk/ov.module.mk", and
# this will do the magic for you!
#
#
