If Catala is compiled without Z3, trying to run it with the backend `Proof` will yield: ``` [ERROR] This instance of Catala was compiled without Z3 support. ``` and return 124 Note that this doesn't change the `make depends`, opam file or CI to account for it, it just enables it at the build-system level. There are also no hooks at this moment to have Catala self-document the options whith which it was compiled (e.g. in the `--help` screen). But that could be added in a more general way later, it's probably not really needed yet.
