Thanks again to Erik for presenting the first official CarpetX tutorial.
You can find the recording here: https://lsu.zoom.us/rec/share/YcrCqkVkEZ5BjqZrXQa-vt7EOGyXFL8rD26-GASPOEhSYv...
Also, inside the cactusamrex repo, there are dockerfiles to create a working CarpetX image.
You can find the working image at this location on dockerhub: einsteintoolkit/cactus-amrex-jovyan
Invoking "build.sh" inside the image should check out (using GetComponents) and build Cactus with CarpetX.
