Apparently Gtest does not set its own version, which leaves it defunct

What happens when trying to use it:

GOOGLETEST_ROOT: /opt/local/src

Looks like GOOGLETEST_VERSION is set to nothing.

buildbots show successful builds on all systems, so you better tell us more about exactly what you’re trying to build on now….

It builds successfully, no issues. But does not work when you try to use it for another port.

Over a dozen ports depend on port:gtest so presumably it worked when that was added to those ports. Can you give an example of one of them that fails this way now?

I think I fixed this issue. However, since you haven't specified the project in which you're encountering this issue, would you be able to test my patch yourself? See ​https://github.com/macports/macports-ports/pull/18739.
