   I wanted to fix this but I'm not sure I'm familiar enough with how conda works yet. Here's what I found in case it helps:
   
   I first confirmed I get the same failure as above and then fixed it by installing zlib manually from conda after I create my env. So I guess that's a short-term fix. Since zlib isn't a new requirement, I wondered why it wasn't being installed when CI creates a new conda env from `cpp/dev.yml`. When I do a dry run against it (`conda env create -d -n foo -f cpp/dev.yml`), zlib isn't listed whereas it is listed if I do dry run on macOS. Is there a good way to find out how a particular dep (zlib) gets pulled in?
