AW: [Insight-users] Which Fltk?!!!???

[Luis Ibanez]

Hi Zein,

These link errors inidicate that the project
is not providing the right path to FLTK
libraries.

e.g. Fl_Gl_Window is a basic class in
      fltk.lib

The problem could be that in your project,
the CMakeLists.txt file is not including
the module "FindFLTK.cmake"

or, that when you run CMake, you are not
providing the right path to the libraries.

or, that your CMakeList does not put the
FLTK_LIBRARIES in the link dependencies of
your executable.

Could you please post your CMakeLists.txt file ?

You may also want to verify the CMakeCache.txt
and look for the FLTK variables. Double check
that they are pointing to the right libraries.

If you wish, please post the FLTK-related
lines of your CMakeCache.txt file. That
could help us to see if something is not
being correctly defined.


   Thanks


     Luis
