oh, yes my bad, I had forgotten the make command in the updated list of commands at the bottom.
updated my post
I did finally succeed at building and running the example after realizing and fixing the version mismatch between the example and the paraview build.
So I don’t really have an issue any more, for now.
My only concern left is that it’s frustratingly hard to compile the example(s) without instructions on how to, and I only succeeded, because a colleague of mine came up with the -DCMAKE_PREFIX_PATH-option that I did not know of.
Instructions on how to compile and run the examples would be fantastic for people like me who have a code that they intend to extend with Catalyst.
