It is worth noting that Qt uses a version script (i.e.
-Wl,--version-script,QtCore.version) which looks like this:

Qt_5_PRIVATE_API {
    qt_private_api_tag*;
    /* some more declarations here */
};
Qt_5 { *; };
Qt_5.0 {} Qt_5;
Qt_5.1 {} Qt_5.0;
Qt_5.2 {} Qt_5.1;
Qt_5.3 {} Qt_5.2;
Qt_5.4 {} Qt_5.3;
Qt_5.5 {} Qt_5.4;
Qt_5.6 {} Qt_5.5;
Qt_5.7 { qt_version_tag; } Qt_5.6
