@dmitry-gorokhov Could someone to approve CI for this PR ?

Hi @redradist. Could you please clarify why we need this patch in OpenVINO oneDNN fork? It is used as a backend for OV CPU Plugin and not supposed to be built targeting NVIDIA GPUs.

@dmitry-gorokhov This patch is needed to be able to compile nvidia_plugin on system with OpenCL 3.0.
Standard mechanism is not working for detecting OpenCL 3.0 version

@redradist Does OV nvidia_plugin uses smt from this oneDNN fork?
Since this fork is used for CPU only, we are disabling GPU build by default (https://github.com/openvinotoolkit/openvino/blob/master/src/plugins/intel_cpu/thirdparty/CMakeLists.txt#L45). In other words cmake/FindOpenCL.cmake shoudn't be called at all.

It is used in OpenVINO for CPU and GPU plugins, in both places I had to modify this cmake to be able to comiple OpenVINO as dependecy and then NVIDIA Plugin

Also, one additional comment, reviously this cmake/FindOpenCL.cmake worked properly, but since NVIDIA update they driver with support of OpenCL 3.0, it is broken (I've mentioned it here as well oneapi-src#2001 (comment))

@redradist My point is OV CPU plugin set DNNL_GPU_RUNTIME to NONE, so cmake/FindOpenCL.cmake is just not installed in that case. Maybe I miss smt, but couldn't really understand how this fork affected GPU build. Maybe you can share details.
OV GPU Plugin uses stock oneDNN library (w/o any forks), so indeed the PR oneapi-src#2001 is required.
