could you help a curious person like me?

Hello, I do not want to be annoying and I feel I should not be asking, is there some way to "compile" "xmr" with cuda 6.5?, I love "xmr" I have been using it for a long time "mining" through the cpu of my pc's , I have many with old video cards and I can not make them work, I know it's for a good reason but I still want to try it. I did a lot of research before I came to the conclusion that I have to do it myself, and I looked for ccminer, it's the only one that supports cuda 6.5 and that "solved" problem, but only that version worked and it's very old, it does not support the crypto's that I want mine, any way, then if there is any way to do it I would like to know it and if so, if you could explain how to do it, that would be great. but it's not totally necessary. I'm sorry for the long post.
