# - Try to find OpenCL
# This module tries to find an OpenCL implementation on your system. It supports
# AMD / ATI, Apple and NVIDIA implementations.
#
# To set the paths manually, define these environment variables:
# OpenCL_INCPATH - Include path (e.g. OpenCL_INCPATH=/opt/cuda/4.0/cuda/include)
# OpenCL_LIBPATH - Library path (e.h. OpenCL_LIBPATH=/usr/lib64/nvidia)
#
# Once done this will define
# OpenCL_FOUND - system has OpenCL
# OpenCL_INCLUDE_DIRS - the OpenCL include directory
# OpenCL_LIBRARIES - link these to use OpenCL
