[Insight-users] How to set CMakeList.txt for indicating the header files?

[Luis Ibanez]

Hi Hon,

Please try adding a lines with the INCLUDE_DIRECTORIES
specifying the directory where you put the files from
FltkImageViewer.  You actually will have to add in this
command both the SOURCE and BINARY directories of the
FltkImageViewer library.  It should look something like


INCLUDE_DIRECTORIES(
   /home/wong/src/FltkImageViewer
   /home/wong/bin/FltkImageViewer
)

The reason for including the binary directory is that
FLTK uses "fluid" for generating C++ code from .fl files.
The C++ files are writen in the binary directory. Henceforth,
the binary directory where you built the FltkImageViewer library
will also contain some fluid-generated C++ header files.


Regards,


   Luis
