[cmake-developers] Proposal to disable link depends inference.

[Matthew Hanna (BLOOMBERG/ 731 LEX)]

Yes, disabling the 'magic guessing' is the primary goal.  I just wanted
to test the waters before embarking on a patch.  Will continue the
conversation once I have a patch ready that solves our problem.

Thanks,
Matthew

IIUC you're not talking about disabling the entire dependency analysis
but instead just turning off the magic guessing of implicit dependencies
based on observed order.  Correct?

Before we bikeshed the name and form of the setting, can you post a patch
that just removes the logic outright so we can see exactly what you mean?

Thanks,
