New issue by Jjp137 on void-packages repository

https://github.com/void-linux/void-packages/issues/47787

Description:
### Is this a new report?

Yes

### System Info

Void 6.1.67_1 x86_64 GenuineIntel uptodate FFFFFF

### Package(s) Affected

gzdoom-4.11.3_1

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

_No response_

### Expected behaviour

GZDoom should display the correct version number (4.11.3 as of this writing) where appropriate, including during startup and within the in-game console.

### Actual behaviour

First few lines of output:
```
$ gzdoom -iwad doom.wad
GZDoom <unknown version> -  - SDL version
Compiled on Nov 18 2023

OS: Void Linux, Linux 6.1.67_1 on x86_64
GZDoom version <unknown version>
```

In-game, `<unknown version>` is shown on the bottom-right corner of the console.

### Steps to reproduce

Run GZDoom from the command line in order to see the terminal output, which is always printed even without an IWAD present.

If an IWAD can be found on your system, after GZDoom starts, open the console (default: ~) and observe that the bottom-right corner says `<unknown version>`.
