Does GammaRay use KDE ?
Ah, I see, e.g. kjobtracker.
So it uses FindKDE4Internal.cmake, then LIB_INSTALL_DIR should not be set like 
this, because it leads to such bad RPATHs, as you see it.

So either LIB_INSTALL_DIR should be set absolute, or unset() before 
find_package(KDE4).

To make it work for you, set it to 
set(LIB_INSTALL_DIR "${CMAKE_INSTALL_PREFIX}/lib${LIB_SUFFIX}")
