That is not planned. Unfortunately the KDS package in CGAL is mostly 
unmaintained. We try to fix bugs, when there are, but important effort like 
porting the demo to Qt4 (or even Qt5) are not done, and will not.

You should install the Qt3 development packages of your Linux distribution 
(which one is it?), reconfigure and recompile CGAL libraries (to have 
libCGAL_Qt3), and then compile the KDS demo.
