add a test which checks that cmake can build the latest stable KDE4 (kdelibs) release

To enable this test, the option TEST_KDE4_STABLE_BRANCH must be switched on.
It can only be switched on if CMAKE_RUN_LONG_TESTS is ON.
Then the test will only be added if Qt >= 4.5 can be found, Perl can be
found and ZLIB can be found.
