Need help for opencvd git submoduling

[Ferhat Kurtulmuş]

I am wrapping opencv::cuda modules based on c/c++ wrapper files 
of gocv. This might be more of a git question. Can one link a 
folder from a repo to be a subfolder of another git repo?
Do I have any option other than submoduling the entire Go repo?

I want "https://github.com/hybridgroup/gocv/tree/release/cuda" to 
be "https://github.com/aferust/opencvd/tree/master/c/cuda"
