Description

#3008 added the buildWithBenchmarks function to default.nix, but only enabled it for cardano-sl-wallet-new. This enables it for all packages with benchmark sections in their cabal file.

Expecting this to fail CI first time because the cardano-sl benchmark should be broken.

LGTM in principle but I wonder if enabling benchmarks will cause CI to take a prohibitively long time (it's already ridiculously long).

Is it possible to just build the benchmarks but not run them?

[ruhatch]

This is supposed to not run them apparently (default behaviour from nixpkgs)

@avieth Just to confirm, this is supposed to build but not run benchmarks.
