[CMake] FLTKConfig.cmake on Microsoft Windows

[Julia Jacobson]

Thanks for your answer. The file FindFLTK.cmake exists within my CMake 
installation, but I still get an error message:
"CMake Error at C:/Program Files/CMake 
2.8/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:91 
(MESSAGE):
Could NOT find FLTK (missing: FLTK_LIBRARIES FLTK_FLUID_EXECUTABLE)"
This is probably due to the fact that I haven't indicated anywhere where 
to find my FLTK installation (i.e. C:\Program Files\fltk-1.1.10).
