Alexander Neundorf b143c335fd make it more robust wrt. #9621 ...

although #9621 did not happen anymore with cmake 2.8.0, probably because
GET_PROPERTY(... GLOBAL ...) now makes the result variable empty instead of
simply not touching it, using FUNCTION() instead of MACRO() makes sure that
the _EnabledFeatures variables is always empty before the GET_PROPERTY()
call (and does not still have the old value from the previous call)
