Hi Ruturaj,
you are right. However, if you are using CMake you shouldn't modify your
compiler's include/link libraries within your compiler's environment; CMake
does it for you.
Thus, concerning the errors you are getting, in CMake's terms, you would
interpret that you are not including FLTK as a library in your CMakeLists.
If the error persisted even after you manually added the FLTK folder, then
the file fltkImageViewer.h is not within that folder.
But anyway, try not to alter the project's properties within your compiler;
you can do that through your CMakeLists.
Make sure also that you include it in your target link libraries' list.
If errors persist, sharing your CMakeLists may be useful.
HTH,
JON HAITZ
