# Module to find OpenColorIO
#
# This module will first look into the directories defined by the variables:
#   - OCIO_PATH, OCIO_INCLUDE_PATH, OCIO_LIBRARY_PATH
#
# This module defines the following variables:
#
# OCIO_FOUND       - True if OpenColorIO was found.
# OCIO_INCLUDES -    where to find OpenColorIO.h
# OCIO_LIBRARIES   - list of libraries to link against when using OpenColorIO

# Other standarnd issue macros
