I just built ITK-4.3.1 + VTK-5.10.0 + FLTK-1.1.10. Then I tried to
configure FLTK (which I built with cmake). For me there was no issue
with finding FLTK. I believe that is because the FindFLTK.cmake on
windows looks for FLTK in the recent cmake builds you have done that
are listed in a registry key. Anyways I did not have the above issue
however still I got the following fatal errors when configuring
ITKApps--4.3.0:

CMake Error at CMakeLists.txt:137 (INCLUDE):
  include called with wrong number of arguments.  Include only takes one
  file.


CMake Error: Error required internal CMake variable not set, cmake may
be not be built correctly.
Missing variable is:
FLTK_FLUID_EXECUTABLE

I am not exactly why this is happening since there is a fluid.exe.
Maybe the finder requires that I install FLUID for a configuration. I
did not do that. I will have to look at this later.
