My regular recommendation is to never use the -qt-<libname> options. You as 
the app distributor should be aware of all the libraries you're shipping, for 
two very important reasons:

1) licensing. Most of those libraries are BSD-3-Clause, which means you need 
to list them and their copyright in your app's documentation. Qt can help you 
in this since there's a "qt_atribution.json" file next to each of the third-
party libraries, so you can simply collect them all and include the necessary 
attributions in your documentation.

2) security. You must be aware of the libraries you can track CVEs published 
against them and update your build within a reasonable timeframe of the fixes 
being published by the upstream developers. Qt will not do this for you.
