Description

I'm trying to build WebEngine on macOS 10.14 or 10.15 with XCode 11.3.1 or XCode 11.5, but so far, all attempts have failed with the same error:

 Maybe you forgot to setup the environment?

I've build and installed Qt 5.15.0 from the same terminal with the same settings (repeatedly), together with many other software packages. Only qtwebengine shows (reproducible) this error.
