It looks like this section is checking for the availability of a bunch
of different components. Do you have all of these listed things
installed correctly? Can you verify that outside of CMake?
SET(FLTK_FOUND 1)
FOREACH(var FLTK_FLUID_EXECUTABLE FLTK_INCLUDE_DIR
FLTK_BASE_LIBRARY FLTK_GL_LIBRARY
FLTK_FORMS_LIBRARY FLTK_IMAGES_LIBRARY)
IF(NOT ${var})
SET(FLTK_FOUND 0)
ENDIF(NOT ${var})
ENDFOREACH(var)

Yep, you're expected to have statements like #include <Fl/Fl.H> in your code.
I found the following comment when Googling around about the issue:
http://cartwheel.idyll.org/browser/trunk/FRII/CMakeLists.txt
So CMake's FindFLTK only looks for FL/Fl.h and FLTK decided that
they like .H better, so it couldn't find FLTK. I replaced the
check with a simpler search for the header file.
My current solution doesn't provide a good way of allowing the user
to specify the location of FLTK.
