Thanks for the tips.

I did have an issue with the RUNPATH.

Now I have:

    Cannot load library /opt/Qt/5.13.2/gcc_64/plugins/platforms/libqxcb.so:
(/opt/Qt/5.13.2/gcc_64/plugins/platforms/libqxcb.so: undefined symbol:
_ZTI26QPlatformIntegrationPlugin, version Qt_5)
    QLibraryPrivate::loadPlugin failed on
"/opt/Qt/5.13.2/gcc_64/plugins/platforms/libqxcb.so" : "Cannot load library
/opt/Qt/5.13.2/gcc_64/plugins/platforms/libqxcb.so:
(/opt/Qt/5.13.2/gcc_64/plugins/platforms/libqxcb.so: undefined symbol:
_ZTI26QPlatformIntegrationPlugin, version Qt_5)"
    qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even
though it was found.

ldd has no missing libraries, but reports:

undefined symbol: _ZTI26QPlatformIntegrationPlugin, version Qt_5
 (./libqxcb.so)
undefined symbol:
