liblacewing is not very well known and is still in alpha development. Any games made with it would be made by me, since I'm a friend of the developer. People are pushing you to SFML and Boost, it looks like you haven't even considered them as options yet.
EDIT: So, I'm a total idiot. Leave me to my stupidity.

Well then chop chop LB, what's the hold up? Nah I'm just messing with you. But you should realize that, assuming your claim isn't exaggerated, the fact that you aren't claiming the title of co-developer calls into question its ... longevity let's say. I've never heard of it until today, but if I were asked in a meeting about it tomorrow I'd say you just torpedoed your "friend". Even us non-devs have to be-able to spot vapor-ware.
EDIT: @OP: SFML is well established, well documented, cross-platform and most importantly IMO, known at this site. What is there left to decide?
