[Insight-users] fltk link errors : Please use CMake

[Luis Ibanez]

Hi Bing,


        Please use CMake !



The linking problems you are facing
are the result of poor configuration.

The real solution is to use CMake for
configuring your project. It will require
only 10 lines of CMake commands to get
this done correctly.

There are more fun things to do in life
than tweaking libraries in the Visual
Studio GUI.  Using CMake will allow you
to get time for those other fun things.

You can start from the CMakeLists.txt
file attached to my previous email.
Simply remove the VTK and ITK sections.



Regards


    Luis
