# - Find OpenCOLLADA library
# Find the native OpenCOLLADA includes and library
# This module defines
#  OPENCOLLADA_INCLUDE_DIRS, where to find COLLADABaseUtils/ and 
#                 COLLADAFramework/, Set when OPENCOLLADA_INCLUDE_DIR is found.
#  OPENCOLLADA_LIBRARIES, libraries to link against to use OpenCOLLADA.
#  OPENCOLLADA_ROOT_DIR, The base directory to search for OpenCOLLADA.
#                    This can also be an environment variable.
#  OPENCOLLADA_FOUND, If false, do not try to use OpenCOLLADA.
#
# also defined, but not for general use are
#  OPENCOLLADA_LIBRARY, where to find the OpenCOLLADA library.
