0001 # - Try to find OpenCL
0002 # This module tries to find an OpenCL implementation on your system. It supports
0003 # AMD / ATI, Apple and NVIDIA implementations, but should work, too.
0004 #
0005 # To set manually the paths, define these environment variables:
0006 # OpenCL_INCPATH - Include path (e.g. OpenCL_INCPATH=/opt/cuda/4.0/cuda/include)
0007 # OpenCL_LIBPATH - Library path (e.h. OpenCL_LIBPATH=/usr/lib64/nvidia)
0008 #
0009 # Once done this will define
0010 # OPENCL_FOUND - system has OpenCL
0011 # OPENCL_INCLUDE_DIRS - the OpenCL include directory
0012 # OPENCL_LIBRARIES - link these to use OpenCL
0013 #
0014 # WIN32 should work, but is untested
