There some changes required at the header to be useful at Windows.
NVidia's OpenCL implementation is available as .dll

I've also tried to launch the Mac's "hello world" example, it did
compile fine, but failed with the error. (something was wrong with
OpenCL program, not pascal code... so much for being cross-platform

Also, OpenCL is designed to be hardware independent layer, so, in
theory, it's NOT necessary to have powerful GPU card. If there's none
OpenCL lib would use CPU for processing. It would be slow, but still
should work.
I've tried Mac "hello world" sample on MacBook with slow Intel
integrated video, and the sample failed if GPU flag is set, but did
work for CPU mode.
