I expect you may run into other issues since velox seems to believe you're on an m1 mac, but is trying to build Folly as x86_64, but I'll put up a diff that should resolve at least this specific error.

Including TargetConditionals.h in folly-config.h should resolve this.

This is still showing up on my Mac M1 as of 9/28/22. I'll try to see if the TargetConditionals.h are included in folly-config.h but I simply followed the instructions from https://github.com/facebookincubator/velox and run into this issue.
