If something is using the export_library_dependencies file then there 
must be a project outside kdelibs involved.  Are you using the same 
version of CMake for both trees?

In CVS CMake I can do

   target_link_libraries(myexe general m)

and it links okay (no -lgeneral).  With CMake 2.4 the command produces 
-lgeneral.  It looks like you're using CMake CVS for the exporting 
project and CMake 2.4 for the importing project.

FYI, the change producing this was done over a year ago in CVS CMake:

revision 1.111
date: 2006-11-29 11:00:17 -0500;  author: martink;  state: Exp;  lines: 
+60 -94
ENH: updated handling of debug and optimized target link libraries
