@Johnnynator  did you try with a `qt.conf` file? See [https://doc.qt.io/qt-5/qt-conf.html](https://doc.qt.io/qt-5/qt-conf.html):

> The qt.conf file can be used to override the hard-coded paths that are compiled into the Qt library. These paths are accessible using the QLibraryInfo class. Without qt.conf, the functions in QLibraryInfo return these hard-coded paths; otherwise they return the paths as specified in qt.conf.

There was an issue in the old repository which sadly is gone now. I tried with this `qt.conf`:
```
[Paths]
Sysroot=
Prefix=/usr
ArchData=/usr/lib/qt5
Data=/usr/share/qt5
Documentation=/usr/share/doc/qt5
Headers=/usr/include/qt5
Libraries=/usr/lib
LibraryExecutables=/usr/lib/qt5/libexec
Binaries=/usr/lib/qt5/bin
Tests=/usr/tests
Plugins=/usr/lib/qt5/plugins
Imports=/usr/lib/qt5/imports
Qml2Imports=/usr/lib/qt5/qml
Translations=/usr/share/qt5/translations
Settings=/etc/xdg
Examples=/usr/share/qt5/examples
HostPrefix=/usr
HostData=/usr/lib/qt5
HostBinaries=/usr/lib/qt5/bin
HostLibraries=/usr/lib
Spec=linux-g++
TargetSpec=linux-g++
```
and think there also had to be made some modifications to `qconfig.pri` and `qmodule.pri`. But something didn’t work out and due to a lack of resources I didn’t pursue it any further.
