[Insight-users] FLTK link problems.

[Hans J. Johnson]

Hello,

I am trying to build the examples for ITK, and I am having a problem 
during the link phase with all programs that require FLTK.   If I 
manually edit the Makefiles and add "-lfltk -lfltk_forms.a -lfltk_gl.a" 
before the locations where "-lGL" appears, then the compilation will work.

To me it seems like the ${FLTK_LIBRARY} from CMakeLists.txt is not being 
filled or processed correctly.

During the configuration stage, I do not know what to put into the 
FLTK_LIBRARY option to make this work properly.

 FLTK_FLUID_EXE                  
/home/hjohnson/src/buildhome/athlon/DEBUG/bin/fluid
 FLTK_INCLUDE_PATH         /home/hjohnson/src/buildhome/athlon/DEBUG/include
 FLTK_LIBRARY                    
 /home/hjohnson/src/buildhome/athlon/DEBUG/lib
but this is wrong because FLTK_LIBRARY should be the full path to a 
single library file.

I have also tried

FLTK_LIBRARY                    
 /home/hjohnson/src/buildhome/athlon/DEBUG/lib/libfltk.a
but this results in unresolved symbols from libfltk_forms.a

FLTK_LIBRARY                    
 /home/hjohnson/src/buildhome/athlon/DEBUG/lib/libfltk.a 
  /home/hjohnson/src/buildhome/athlon/DEBUG/lib/libfltk_forms.a 
 /home/hjohnson/src/buildhome/athlon/DEBUG/lib/libfltk_gl.a
but this results in an error during the generation of the Makefile from 
within ccmake (something like "can not extract filename from 
 /home/hjohnson/src/buildhome/athlon/DEBUG/lib/libfltk_gl.aCMakeLists.txt")

Thanks in advance for your help.
