Synchronization of .cmake files

[keceli]

We had an action to sync .cmake files with DeveloperTools across different NWChemEx repos, but after abandoning DeveloperTools, we don't have a similar action in .github repo. Should we add back the sync action here or is there a way to use these files from this repo? If no to both, is there a better way than manually updating such common files across different repos?

We're no longer synching files like this. The action which did it was pretty fragile and was more or less a work around for a real solution.

We have a couple of CMake modules which show up in each repo. It's probably best to put those in some repo, CMakeTools, or something, and then pull them into the builds via FetchContent. CMakeTools could eventually be a central place for storing the versions of our dependencies too.
