        This package allows building with either GTK-3 or GTK-4, but not both
        in the same build. The GTK-4 version is needed for packages such as
        <xref linkend="epiphany"/>. Other packages, such as
        <xref linkend="balsa"/> or <xref linkend="evolution"/>, require the
        GTK-3 version. Both versions can be installed side by side on the
        same system. We give build instructions for both cases below, but
        the only difference is the setting of <command>-DUSE_GTK4</command>
