Please try again with the upcoming nightly builds. For Cristian they make things
work better: Initial project tree setup went down from 140s to 2s for his
project. I hope you will see similar results.

In master I want to move the whole project tree creation into a thread.
Unfortunately the preparation took too long to get this into 4.3 :-/

That is still on my Todo list, sorry.

It probably is: I do not see that issue with my projects. But Cristian has
reported the same issue, so you are not alone:-)

That _should_ be safe with server mode (and ignored in the tealeaf reader).

No. The Project is basically just a kind of tag that gets assigned to the
CMakeLists.txt files that contain PROJECT.

That might be what is causing the multiple Source directories. I'll need to look
into that.

You are welcome.
