[Windows][OpenCL][Intel] FindOpenCL.cmake module cannot seem to find installed OpenCL SDK

Testing OpenCL Caffe in Windows on Core i5-4210U. Installed latest OpenCL SDK, runtime, and drivers. Tried setting OPENCL_LIBRARIES and OPENCL_INCLUDE_DIRS to many combinations, but it doesn't help.

C:\projects\caffe>scripts\build_win.cmd The system cannot find the drive specified.

Workaround is to manually copy the x64-bit OpenCL.lib "file" and "CL" folder to C:\Users\billgates\.caffe\dependencies\libraries_v140_x64_py35_1.1.0\libraries\lib and C:\Users\billgates\.caffe\dependencies\libraries_v140_x64_py35_1.1.0\libraries\include folders respectively and re-run installation.

[naibaf7]

Try again with the updated Makefiles, please.

Really odd... I tried again and it finds both AMD SDK and CUDA on my installation with valid OpenCL 64bit. Must be something strange with your OpenCL from Intel.

[atlury]

Can you try once from your side with OpenCL from Intel in windows? (if time permits and if life allows it)

[naibaf7]

Yeah I'll try to set up Windows on my Intel laptop, but after NIPS submission deadline.

@naibaf7 I am facing exactly the same problem, have you had chance to test it? Is this problem solved? Thanks!

[bxk-sonavex]

@naibaf7 The tricks (workaround) from @atlury worked for me.
