write nvidia make settings in readme

[montvid]

To compile your miner on cuda 8.0 I need to write the path and only then it compiles:

make OPENCL_HEADERS=/usr/local/cuda-8.0/targets/x86_64-linux/include/ LIBOPENCL=/usr/local/cuda-8.0/targets/x86_64-linux/lib

That will be very system specific.

System specific but usefull if you have many devices that could do OpenCL compute. I have a rig with AMD and NVidia cards, I should specify headers & libs paths when doing a make, and set the LD_LIBRARY_PATH to the correct libs before running the executable.

If you have only AMD or NVida, then it's a misconfiguration when you installed the driver and SDK, or a missing symlink somewhere.

Check out ocl-icd, it is library that loads correct driver for each card.

Well I might as well use real-world paths in my example. Done: ddb3ec7
