Cannot run without qt3 library 'libqt-mt.so.3'

[kellcodes]

I have compiled xxdiff from git on Almalinux 8.5 with all qt5 modules installed (there is no qt3 package provided natively). I am able to build xxdiff, however I am not able to run the package as I receive an error

error while loading shared libraries: libqt-mt.so.3: cannot open shared object file: No such file or directory

The aforementioned library is provided with qt3, however does not appear to be packaged with qt5. Despite the absence of this library, xxdiff compiles with no errors.

Operating system: AlmaLinux 8.5
QT version: 5.15.2

I have additionally modified the xxdiff.pro source file to remove 'thread' from the CONFIG line, however this has not helped.
