You can submit a feature request for LIST(FILTER) here:

I'm assuming you're asking this as a follow-up to the previous thread on
file globbing.  It is not recommended to construct the source list using
globbing.  When a source is added there is no change to CMakeLists.txt
files so cmake cannot automatically re-run on the next build.
