I've been using FetchContent a lot recently, and it works pretty well. It would be good to provide an example of how it works for those learning. Also, it should include some of the content from the Integrating with find_package section of the manual.
There are a few cases that could be covered:
Dependency has no dependencies
Override dependency's find_package calls
Defer to find_package calls when available
Order multiple dependencies correctly
Set CMake options for a dependency, e.g. enabling specific components
