Where are you looking? Where will I see these compiler arguments that you
refer to?

This:
https://docs.kde.org/trunk5/en/extragear-kdevelop/kdevelop/kdevelop.pdf
Yes, but there is no mention of "defines" as far as I can see. Are they
called something else in the handbook?

I don't see where it explains how to correctly set up include paths either.
Do I need to manually add every directory in the project?

Yes, I've seen where to add defines, but Audacity has hundreds of defines.
How did you know which defines needed to be added to kDevelop's
configuration?

Is there anyone in the kDevelop team that might be interested in, a) fixing
the crash bug, b) helping the Audacity team to document setting up kDevelop
for use with Audacity's code? Perhaps we can come to some arrangement that
gives mutual benefit.
