How to connect CUDA in go?

Here is an example https://github.com/miguelzambrana/cudagolabs . I compile and this is what I get

# github.com/mumax/3/cuda/cu
C:\Go\src\github.com\mumax\3\cuda\cu\context.go:5:18: fatal error: cuda.h: No such file or directory
 //#include <cuda.h>
                  ^
compilation terminated.
# github.com/barnex/cuda5/cu
C:\Go\src\github.com\barnex\cuda5\cu\context.go:5:18: fatal error: cuda.h: No such file or directory
 //#include <cuda.h>
                  ^
compilation terminated.

I also used other assemblies on go for cuda. Didn't see it either. Specified manually and here
