Does UE compilation require Qt 5?

How to build UE 5.1 from source on linux detecting the right engine version

Run ./Setup.sh.

During this, I saw some errata (chronologically undermentioned):

1. This shouldn’t be X11 these days. Regardless, it could at least adhere to the DE’s anti-alias preferences.

2. Removing corrupt toolchain and redownloading

This probably isn’t of any importance, considering that UE remediated it.

3. /usr/bin/xdg-mime: line 885: qtpaths: command not found

Considering that dnf5 provides /usr/bin/qtpaths returns results:

qt5-qttools-5.15.17-1.fc42.x86_64 : Qt5 - QtTool components
Repo         : updates
Matched From :
Filename     : /usr/bin/qtpaths

…this is worrisome. It should have prompted me to install it. In fact, every time I register the installation:

…I see it again:

RokeJulianLockhart@Beedell:~/Documents/The_Unsanitised/Git_Repositories/Unreal_Engine/Engine/Binaries/Linux$ ./UnrealVersionSelector-Linux-Shipping
5.1.0-23329225+++UE5+Release-5.1 1008 0
Disabling core dumps.
/usr/bin/xdg-mime: line 885: qtpaths: command not found

KDE Plasma 6 utilises solely Qt 6, so I’d rather not have Qt 5 installed, if possible.
