Is there a way to set `output-dir` from the command line? I tried with `-M output-dir=...` but it doesn't seem to work.

The reason I'm asking is that I have a book in two languages, with both languages sharing the same source files (so they can share non-text elements). For example a source can look like this:

```
[Some text]{lang=fr}
[Some text]{lang=de}
$some shared math equation$
...
```

For rendering, a Makefile runs quarto once with `-M lang=fr` and once with `-M lang=de`. A Lua filter is used to keep only the text for the selected language. To keep things cleanly separated it would be nice to have each run working in a different directory (e.g. `_book/fr` and `_book/de`).
