build.py broken in r24.11

[prm-james-hill]

Description

This works:

git clone [email protected]:triton-inference-server/server.git
git checkout r24.10
python3 build.py

But after doing git checkout r24.11 or git checkout r24.12 and rerunning build.py I get the following error:

Triton Information
r24.11 is the first version I see this behavior in.

To Reproduce
See above description. I also tried with various tag and backend options but it didn't impact it. (EDIT: After enabling 90% of options it appears to work. I don't know which option is providing this header or fixing the include, though.) I'm on Ubuntu 24.04.

Expected behavior
Build script to finish without error.
