[Insight-users] Compiling DicomImageViewer outside InsightApplications

[Luis Ibanez]

Hi Vries,

The DicomImageViewer, as well as many other applications in 
InsightApplications, use the FLTK for its GUI. They also share
a basic set of classes for image viewing, that are located
in the directory:

    InsightApplications/Auxiliary/FltkImageViewer

You will have to add this directory / library to your project
in order to be able to build the DicomImageViewer.

You could do so, by copying this directory under the one
of your application, and then including a command:

        ADD_DIRECTORIES(FltkImageViewer)

to your CMakeLists.txt file.



     Regards,


        Luis
