According to the referenced mail a QT_HAS_FEATURE() macro ought to be the replacement?

(that being said I think I like this better as the presented change would also work with qt4)


phonon/CMakeLists.txt (line 15)
<https://git.reviewboard.kde.org/r/129256/#comment67319>

    Please keep the if ordered as it was to reduce the diff and make this easier to read at a glance without the double negation.
    
    if (phonon_no_dbus || !qtdbus_found)
       // disable
    else
       // enable
