New issue by b1scu1t on void-packages repository

https://github.com/void-linux/void-packages/issues/15426

Description:
### System

* xuname:  
  `Void 4.19.77_1 x86_64 GenuineIntel notuptodate rrrmFFFFF`

* package:  
  `ardour-5.12_3`

### Expected behavior
Installing the `ardour` package would include a .desktop file for application menus. (Given that it is a QT GUI).

### Actual behavior
The .desktop file isn't included or installed.

### Steps to reproduce the behavior
`sudo xbps-install -S ardour`
