google-test subdirectory fails to build (-Werror)

In attempting Task 2/14, compilation fails when checking the answer as google-test fails to build due to -Werror=maybe-uninitialized:

This is due to google-test < 1.11.0 failing to cleanly build with GCC >= 11. See https://github.com/google/googletest/issues/3219

This could be fixed by passing -Wno-error to cmake, patching the subdirectory with the closing commit on the issue linked above, or updating the google-test version.

Manually updating cmake/googletest-download.cmake to add release-1.11.0 fixes this issue for me.
