Tim Wojtulewicz d62e966234 Fix macOS Big Sur builds on Cirrus ... - Upgrade the Big Sur VM to use the Xcode 12.5 version. This has a newer version of brew installed on it that fixes an issue with an EOL package host that finally shut down for good recently. - Use 'brew upgrade' for openssl and cmake, since those are both present on the base VM. This prevents 'brew install' from printing an error if the package exists but is out of date.		2021-06-09 09:11:37 -07:00
