[vtkusers] FLTK and VTK on VC++

[Sean McInerney]

Hi Hassan,

A couple points:

1. Fl_Window should be included as <FL/Fl_Window.H>
2. I have never had the compile-time problem finding 'floor' using VS71
or BCB5.5 on Win32 or GCC on Linux and Solaris, so I think that the
include order for <math.h> may be a red herring.
3. You should be using CMake for your build process. Handcrafting
makefiles for a project using VTK is not recommended.

Have a look at either my or Charl Botha's VTK - FLTK projects.

Good Luck!

-Sean
