Dumped the pure SFML folder. Got it working enough to realize that it just ran too slow to continue wasting time on it. SFML creates a OpenGL context anyway so users can drop in the nk_sfml_gl2.h and not need anything else. I'll have to add this in the readme. Tried to make my code as similar to other demos for sake of consistency.
