# Locate Chipmunk physics library
# This module defines
# CHIPMUNK_FOUND, if false, do not try to link to Lua 
# CHIPMUNK_LIBRARIES
# CHIPMNK_INCLUDE_DIR, where to find chipmunk.h 
#
# Note that the expected include convention is
#  #include <chipmunk.h>
# and not
#  #include <chipmunk/chipmunk.h>
# This is because, the chipmunk location is not standardized and may exist
# in locations other than chipmunk/
