When it's just a matter of adding -L /usr/kde/svn/lib, then the correct way to 
proceed is adding a link_directories( /usr/kde/svn/lib/ ) command to 
CMakeLists.txt.
Ideally one should write FindSmokeQt.cmake, FindSmokeKDE.cmake, 
FindSmokeQtWebKit.cmake etc. and install them together with the smoke libs. 
You could then simply find_package (SmokeQt REQUIRED) and everything should be 
set up correctly. Without that, a hardcoded link_directories command as 
explained above should be sufficient.
