The build fails when trying to look for OpenCL version 1.2 not found,

Hi, you have to install newest nvidia driver to have support for OpenCL 1.2. For Windows platform it is a driver version 350. and above. For linux it is driver 352.21 After installation please execute clinfo program to check if it showing something similar to this output:

Number of platforms                               1
  Platform Name                                   NVIDIA CUDA

The driver supports 1.2, but the problem is with the header files.

@kvaragan You can download OpenCL 1.2 headers from Khronos to fix the builds.

@kvaragan I think you can close this issue; it's resolved right?

I have to check this issue, then I will close it, till now I have not used clSparse on NV, I have been only using cuSPARSE.
