Description:
### Is this a new report?

Yes

### System Info

Void 6.6.11_1 x86_64-musl GenuineIntel uptodate rrnFFF

### Package(s) Affected

contour-0.4.1.6292_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

https://github.com/contour-terminal/contour/issues/1397

### Expected behaviour

Open a window with the contour terminal

### Actual behaviour

The program does not open and when launched from a terminal issues:
```
Warning: QQmlApplicationEngine failed to load component ((null):0, (null))
Warning: qrc:/contour/ui/main.qml:30:5: Type Terminal unavailable (qrc:/contour/ui/main.qml:30, (null))
Warning: qrc:/contour/ui/Terminal.qml:8:1: module "Qt5Compat.GraphicalEffects" is not installed (qrc:/contour/ui/Terminal.qml:8, (null))
```
and then hangs

### Steps to reproduce

1. install contour
2. try to launch contour
3. watch it hang/crash
4. mitigate by installing the 'qt6-qt5compat' package
5. launch contour in working order and without error messages
6. Profit ???
