Tried to reproduce, works just fine here.

You're trying the kf5 build, right?

Do you have a valgrind trace or something?

BTW, the current master doesn't build
https://build.kde.org/job/knights%20master%20kf5-qt5/PLATFORM=Linux,compiler=gcc/24/console


BTW2, you have a valgrind warning just starting up

Just install into a prefix you want and set LD_LIBRARY_PATH to point there, 
these are some of the exports i have for using that prefix instead of the regular one, at this point i'm not sure all of thema
are needed, but they don't seem to hurt much

export KDEDIR=MY_INSTALL_PREFIX
export KDEDIRS=MY_INSTALL_PREFIX
export PATH=MY_INSTALL_PREFIX/bin:$PATH
export LD_LIBRARY_PATH=MY_INSTALL_PREFIX/lib:MY_INSTALL_PREFIX/lib/x86_64-linux-gnu/
export PKG_CONFIG_PATH=MY_INSTALL_PREFIX/lib/pkgconfig
export XDG_DATA_DIRS=MY_INSTALL_PREFIX/share:/usr/share
export QT_PLUGIN_PATH=MY_INSTALL_PREFIX/lib/kde4/plugins:MY_INSTALL_PREFIX/lib/x86_64-linux-gnu/plugins
export STRIGI_PLUGIN_PATH=MY_INSTALL_PREFIX/lib/strigi
alias cmake="cmake -DCMAKE_INSTALL_PREFIX=MY_INSTALL_PREFIX -DCMAKE_BUILD_TYPE=debug"

https://quickgit.kde.org/?p=scratch%2Fapol%2Fprefixsetup.git is supposed to have something like this but at this point i can't get quickgit
to work for me so i can't check
