Missing OpenCL after installing drivers - LightGBM GPU installation


I’m trying to install LightGBM on my Windows 10 system and I have version 425.31 of the drivers installed for GTX 1070.

LightGBM looks for OpenCL.lib and OpenCL in include directory. I’ve updated my drivers to latest one from Version 419 but still can’t find these.

I also have CUDA 10.1 installed on my system. I’m looking for OpenCL in the folders ‘C:\Program Files\NVIDIA Corporation’ and ‘C:\Program Files\NVIDIA GPU Computing Toolkit’

Can anyone please help me on how to get them?

Please let me know if you need any further information.
