cannot find -lOpenCL #7

Forgive me if Windows installs aren't supported, but I'm running into the following issue when trying to build on Windows 10 with mingw64 and an nvidia gpu.

$ go get github.com/robvanmieghem/gominer
# github.com/robvanmieghem/go-opencl/cl
/usr/lib/gcc/x86_64-pc-cygwin/5.4.0/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lOpenCL
collect2: error: ld returned 1 exit status

I'll keep trying to get this working, but thought I'd post in case you know the solution off hand.

It means that the linker can not find the OpenCL library. You have to set the library path properly for the linker to find it. For example, in powershell, on a system with the intel sdk installed, you can execute the following command before executing go get or go build:

PS>  $env:LIBRARY_PATH = "C:\Program Files (x86)\Intel\OpenCL SDK\lib\x64"
