Does the file api enumerate test cases? I thought there was a change that introduced that, but I couldn’t find anything in CMake’s gitlab, so I’m probably misremembering. The main reason I’m asking is that if it does, then the `DISCOVERY_MODE` option added to `gtest_discover_tests()` in CMake 3.18 would be a potential problem - test cases wouldn’t be known at CMake generation time.
