# - Try to find OpenCL
# This module tries to find an OpenCL implementation on your system. It supports
# AMD / ATI, Apple and NVIDIA implementations.
#
# Once done this will define
# OPENCL_FOUND - system has OpenCL
# OPENCL_INCLUDE_DIRS - the OpenCL include directory
# OPENCL_LIBRARIES - link these to use OpenCL
#
# WIN32 should work, but is untested
