It looks to me like CONFIGURE_FILE is a no-op when the target file

CONFIGURE_FILE ran.

I'm basing me belief by looking running some experiments and looking
at timestamps.

But this isn't mentioned in the online docs for CONFIGURE_FILE.

Does anyone know if it works the way I describe?

That's correct - otherwise all your sources (which includes the config file) would get recompiled after each cmake run.
