Description

We have evidence (see Slack thread) that CVC5 is more successful than Z3 in dealing with some non-linear arithmetic problems arising in rules' side condition in kasmer and kontrol.

We have for a long time considered adding CVC5 as an alternative/companion solver to Z3.

We should start with the simplest possible implementation: use CVC5 instead of Z3, controlled by the --smt-solver command line option.

Research direction

The issue names no files or tests. Start by tracing the existing Z3 path behind the --smt-solver option and its handling of side conditions in kasmer and kontrol. Done means selecting cvc5 through that option uses it instead of Z3 for the relevant solver calls.
