# Builds the CLI, the directory service and the SMP server that the app job runs as its test backend.
# Usage: scripts/ci/desktop-linux/build-backend.sh <output .tar.gz>
# They need the server-capable configuration (no client_library), as build.yml's Linux job builds the CLI.
# The SMP server, which resolves the test's SimpleX names, comes from a clone of the simplexmq commit that
# cabal.project pins: cabal builds only the libraries of a source-repository-package.
