fltk: rework completely

* Use cmake as build system. Projects also using cmake and depending on fltk
  would not find all required components. Note that FindFLTK.cmake is part of
  cmake.
* Add a native recipe and split out common - we need fluid (Fast Light User
  Interface Designer) as working binary
