gtest test targets fail with "Unknown test selection: 'gtest'" on jdk15-17

[Thomas Stüfe]

Hi Abigail,

at some point (it may have been JDK 15, I am not sure atm) we stopped
including the google test framework in our repo and instead require the
builder to provide it externally. See configure option "--with-gtest". Must
point to a copy of the googletest framework (
https://github.com/google/googletest).

HTH, Cheers, Thomas
