      <para>
        Even though this package can be built against
        <application>Qt5</application>, the instructions below don't
        cover such installation because the changes needed to the
        instructions below are too invasive. If you need
        <application>Qt5</application> version of the library, check
        the "KDE Frameworks 5" chapter for instructions.
