Unable to build: Dependency "OpenBLAS" not found

I have been trying to build Orion on my Fedora 41 system with Python 3.11 without success:

> git clone <repository_url>
> cd orion
> python3.11 -m venv .
> source bin/activate
(v3.11.11/orion) > pip install -r requirements.txt
...
      ../scipy/meson.build:169:9: ERROR: Dependency "OpenBLAS" not found, tried pkgconfig and cmake

Can you instead use this Dockerfile https://github.com/cloud-bulldozer/orion/blob/main/Dockerfile ?
