# - Try to find OpenCL

# This module tries to find an OpenCL implementation on your system. It supports
 
3
# AMD / ATI, Apple and NVIDIA implementations, but shoudl work, too.

# Once done this will define
 
6
#  OPENCL_FOUND        - system has OpenCL
 
7
#  OPENCL_INCLUDE_DIRS  - the OpenCL include directory
 
8
#  OPENCL_LIBRARIES    - link these to use OpenCL

# WIN32 should work, but is untested
