Installing Smooch on macOS: Missing C libraries

What is the current behavior?

When running stack build on macOS, the build exits with the error message:

* Missing C libraries: icuuc, icui18n, icudata

What is the expected behavior?

We expect that stack build should build Smooch without error.

Which browser / OS are affected by this issue? (An isolated way to reproduce the bug)

OS: macOS

This looks like a macOS and Mac OS X specific issue when trying to build a Haskell app for the first time (see here, for a similar issue with a Haskell app).

stack install text-icu --extra-lib-dirs=/usr/local/opt/icu4c/lib --extra-include-dirs=/usr/local/opt/icu4c/include resolves this. It would be helpful to include this as part of the installation instructions in the sections re: stack build command (and probably with an explanation of why this happens and what this command does that fixes the build process), maybe even think about adding a troubleshooting section in the contributing doc?

@aklap Oh interesting! I don't think I've seen those before -- but it might be that it's just been a long time since I first started using Haskell on Mac. I agree this would be really helpful information to have in the documentation.
