Am I not already asking "on the list"?
So far I've tried this mailing list, the kDevelop forum and the kDevelop
IRC Chat (as described https://www.kdevelop.org/support). Where should I go
for support? Is this not the official support channel?

Are you saying this is a "bug"?

What do you mean "included via a compiler argument"?
The compiler arguments that I use (successfully) are:
../configure --with-lib-preference="local system" --with-ffmpeg="system"
--disable-dynamic-loading --with-mod-script-pipe --with-mod-nyq-bench
--enable-debug

Interesting. Is there any documentation about custom defines in kDevelop?
How did you know to add those custom defines?
Could other custom defines be required?
