Weird error trying to build Libre Office from source

[rubisetcie]

Hello dear Libre Office developers, I hope you are doing alright.

I am used to build Libre Office from sources, but I am encountering a
problem for the first time, and I am struggling to find more infos in the
docs, since they're pretty old...

The error message is the following:
ERROR: Node '/Drivers/Installed' does not exist in schema!

Would there be a way to bypass the schema validation? Or, would you help me
figuring out why it's invalid?

Thank you very much in advance!
