I did the same with one of small games I have developed. It wasn't that hard. I only needed to tweak the build script and to fix some minor issues, like changing how main function works and swapping color components in the result picture. I did use SDL2 for it, but without OpenGL, so, I had no problems with shaders or something similar.
