[Insight-users] Re: FltkImageViewer Problem

[Luis Ibanez]

Hi Andy,

You are missing to include the configuration
for FLTK. Please add the following lines to
your CMakeLists.txt file:


    FIND_PACKAGE(FLTK)
    IF(FLTK_FOUND)
      INCLUDE_DIRECTORIES(${FLTK_INCLUDE_DIR})
    ENDIF(FLTK_FOUND)

then rerun CMake and provide the locations
of all 6 FLTK components.

Please look at the FAQ for details

Regards,



    Luis
