- This deprecates the OPENCL_VERSION_STRING result variable.
- Documentation adjusted.
- Support for OpenCL 3.0 was added in CMake 3.24.
- Added CL_TARGET_OPENCL_VERSION compile definition to test so that
program compiles without warnings.
- Additionally, on Apple systems compiler can't find <Headers/cl.h>
unless direct path would be passed as a header. Instead, <OpenCL/cl.h>
is used for version check conditionally.
