I am trying to use cycles standalone as a library in a separate product, and found some small issues while integrating it with my code. How can I contribute my patches?
Hi! Please see the wiki pages linked below.

Please share with us a link to your separate project 
I’d like to see how Cycles is being used outside the Blender world!
