Or generated by some other process, outside of this particular make
invocation, yes.

A common practice is to have a central repository of objects and/or
sources that are already built. This can greatly reduce build times.
These days this model is not as useful since disk space and system
speeds have increased so dramatically that the savings are often not
worth it, except in more unusual situations.
When this capability was added, back in the early 1990's, it was more
widely used.
