Brad King a1eb03569d file: Change REMOVE to ignore empty names
Previously code like

    file(REMOVE_RECURSE "${accidentally_missing_variable}")

treated the empty string as a relative path with respect to the
current directory and removed its contents.  Change this behavior
to ignore the empty string with a warning instead.

Normally such behavior changes are done with a policy, but in this case
such code is likely a real bug in project code that can delete data.

Fixes: #19274
