CL/cl2.hpp, which the OpenCL support is based upon, is not always included with OpenCL on some platforms, e.g. Mac, or not readily available as a package. This work adds a CMake module specifically for finding cl2.hpp, as installed by OpenCL-CLHPP project. If not found, but standard OpenCL lib and headers are, the vendored cl2.hpp in external/opencl-clhpp is used, as it needs no compilation. - Only the cl2.hpp, license and README are vendored from OpenCL-CLHPP. - Fix up referenced includes in other CMake targets, to ensure the includes for OpenCL are specifically added (previously, they were sometimes found in existing include directories of other dependencies). - Fixup for standard FindOpenCL module not assinging proper framework headers directory for Mac.

# CMake module to search for OpenCL headers for C++ bindings from:

|
|
# Specifically, it finds the cpl2 header.
|
|

# If it's found it sets OPENCL_HPP_FOUND to TRUE
|
