I'm still facing this problem and now I have no idea how to solve it. 
kdewidgets is being linked like this:

/usr/bin/c++ -fPIC -O0 -g -W<snip_flags> -fno-exceptions -fno-check-new -fno-common \
-Wl,--fatal-warnings -Wl,--no-undefined -lc -shared -Wl,-soname,kdewidgets.so -o \
../lib/kdewidgets.so  <source_files> -L/usr/local/lib \
-L/home/thiago/obj/kde4/KDE/kdelibs/lib/. -L/home/thiago/obj/kde4/KDE/kdelibs/lib \
-L/home/thiago/obj/troll/qt-main/lib -L/lib -lkio -<lots_of_libs> \
-Wl,-rpath,/home/thiago/KDE4/lib

If I modify KDE4Macros.cmake and remove the INSTALL_RPATH "" part from 
KDE4_HANDLE_RPATH_FOR_LIBRARY, I get closer to my goal:

/usr/bin/c++ -fPIC -O0 -g -W<snip_flags> -fno-exceptions -fno-check-new -fno-common \
-Wl,--fatal-warnings -Wl,--no-undefined -lc -shared -Wl,-soname,kdewidgets.so -o \
../lib/kdewidgets.so  <source_files> -L/usr/local/lib \
-L/home/thiago/obj/kde4/KDE/kdelibs/lib/. -L/home/thiago/obj/kde4/KDE/kdelibs/lib \
-L/home/thiago/obj/troll/qt-main/lib -L/lib -lkio -<lots_of_libs> \
-Wl,-rpath,/home/thiago/KDE4/lib

Note that there's only one RPATH entry there. Why isn't Qt's libdir being 
added?

Any hints?
