OK, per
http://public.kitware.com/Bug/view.php?id=11751#c25029

So, some options to consider:

1.  we/kde could add a helper macro something along the lines of:

macro(kde4_append_install_rpath dir)
  list(FIND CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES "${dir}" _isSystem)
  if("${_isSystem}" LESS 0)
    list(APPEND CMAKE_INSTALL_RPATH "${path}")
  endif()
endmacro() 

and replace every common use of
set(CMAKE_INSTALL_RPATH "${LIB_INSTALL_DIR}")
with
kde4_append_install_rpath("${LIB_INSTALL_DIR}")


2.  copy-n-paste the aforementioned code all over (similiar to what's 
already in FindKDEInternal)


3.  wait for cmake to handle this better natively
