[Insight-users] legacy code in ITK applications and FLTK version

[Julien Jomier]

Hi Ruben,

It is strongly recommended to use an installed (make install) version of 
FLTK, since FLTK installation creates symbolic links to the right 
headers. An other option is to use CMake to configure FLTK (CMake 
actually creates the symbolic links to the binary directory).

Also, as you mention, ITK applications are not compiling with FLTK 2.0.

I'm adding these comments on the Wiki.
Thanks,

Julien
