Those are down in Source/kwsys which is a directory shared by
projects other than just CMake.  We cannot touch the files there.
Instead you will need to re-factor things to go through a wrapper.
The first stage will just wrap up the KWSys regular expression API.
The second stage will replace the implementation with TRE.

That should be fine.
