{-| This test tries to compile the Helper against every supported version of the
Cabal library. Since we compile the Helper at runtime, on the user's machine,
it is very important to make sure this will not fail to compile.
This test only covers using v2-build to install the requested Cabal library
version because it has the best build product caching (keeps CI times
down). We could also use stack since it has a global package cache but we
don't support that because stack always comes with the right Cabal library
version available for a given resolver anyways.
