It would be good if we can detect the version of the googletest and report an error if it's not 1.8.1. However, in https://github.com/google/googletest/archive/refs/tags/release-1.8.1.tar.gz, I couldn't find any file that contains the version information. The only file that contains some sort of version number doesn't have the right version:


./googlemock/configure.ac:        [1.8.0]


Maybe `make doctor` can print out some hints about 1.8.1 if it finds that the gtest build has failed?
