Is there a way to use a system ghc with `isabelle ghc` and `isabelle ghci`? I want to avoid the 145MB download and extra installation of ghc if possible. Note in particular that setting ISABELLE_GHC now has a peculiar effect on `isabelle ghc`. Without the environment variable, the command complains: Cannot execute ghc: missing Isabelle GHC setup However, if ISABELLE_GHC is set in $ISABELLE_HOME/etc/settings, then the same command starts downloading ghc via stack... > isabelle ghc Preparing to install GHC (tinfo6) to an isolated location. This will not interfere with any system-level installation. Preparing to download ghc-tinfo6-8.4.4 ...^C Given the size of the download I find this unsatisfactory (145 MB is still big for mobile plans.)
