Merging KAuth into KDELibs

[John Tapsell]

I just 'fixed' a compile problem in cmake/modules/FindPolkitQt.cmake

I replaced:

        if ( NOT (POLKITQT_PREFIX STREQUAL CMAKE_INSTALL_PREFIX) )


with

        if ( NOT POLKITQT_PREFIX STREQUAL CMAKE_INSTALL_PREFIX )

I hope this was correct.  Please yell at me if not.
