Bug 285503: x11-themes/qt5-style-plugins reinstall needed after qt5 upgrade
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=285503



--- Description ---
Every upgrade of Qt5 ports/packages breaks ALL Qt5 applications if
x11-themes/qt5-style-plugins port/package is installed. They are failed to
start with the following errors (Qt versions can be different):

Cannot mix incompatible Qt library (5.15.14) with this library (5.15.16)

The error origin is Qt5 plugin
/usr/local/lib/qt5/plugins/styles/libqgtk2style.so installed by the
port/package x11-themes/qt5-style-plugins. It seems that this package was
rebuilt using the current version of Qt library, but the package version was
not updated.

The problem is solved for me after reinstall of the package
x11-themes/qt5-style-plugins (the version of the package is the same as
before).

This problem is really confusing, notably for an 'average' user. Many
applications don't start after package upgrade - it looks very very bad.
