Closed issue by xyzz on void-packages repository

https://github.com/void-linux/void-packages/issues/32497

Description:
### System

* xuname:  
  Void 5.12.19_1 x86_64 AuthenticAMD uptodate hold rrrrmdFFFFFFFF
* package:  
  *affected package(s) including the version*: LibreCAD-2.1.3_3

### Expected behavior

LibreCAD has several default plugins documented in https://librecad.readthedocs.io/en/latest/ref/menu.html#plugins - these should be accessible via the "Plugins" menu. To confirm this, I've installed LibreCAD 2.1.3 on windows using their official installer and the following plugins are present:

### Actual behavior

After installing LibreCAD from Void Linux repos, the "Plugins" menu is empty (this is after trying to click on the menu):
