CMake: Document FLTKConfig.cmake and set FLTK_INCLUDE_DIR

Browse Source 
Some of the output variables had not been documented, and the "new"
variable for FLTK include directories is 'FLTK_INCLUDE_DIRS' (plural)
rather than 'FLTK_INCLUDE_DIR'.

FLTK_INCLUDE_DIR is now also set for compatibility with FindFLTK.cmake
supplied by CMake.
