Platform information (please complete the following information):

• OS: Debian 12.4
• Qt version 5.15.8
• gcc 12.2.0
• Version from git

Additional context

Maybe i was missing a deb package to install. But which one ?

I was researching the other day and it seems that qtlocation5-private-dev is not built for Debian for some reason. At least it's also not available on Ubuntu. Not sure how to solve the issue in a simple way.

If there are only headers in this package - could manually be copied from qt-source to the destination ?

In this case the question is what files are required.
