The CMakeLists.txt includes external project setup, but on my machine, I don't see that it downloads anything. It creates a few empty directories though. Any help highly appreciated!

Hi @chrr. What are your underlying OS/architecture and CMake version?

Edit: I'm able to reproduce this issue with CMake <3.22. If your version is older than this, please upgrade and report back.

Thank you! OS is Ubuntu 20.04, with cmake 3.16.

Upgraded now to 3.26.4, and the problem vanished.
