Porting FLTK to NuttX RTOS

Hi csanchezdll, I was looking your PR on NuttX repo and decided to look at your projects.

Do you think it could be possible to get FLTK working on NuttX on top of NanoX (http://www.microwindows.org) ?

I think it could open doors to run many interesting application from Linux on NuttX, i.e. Dillo web browser. Please feel free to reach me if you are interested on it: acassis at gmail dot com
