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

|
#
|
||
|
|
# 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
