> {{verify-release-candidate.bat}} uses the following command to run the C++ tests:
> {code}
> ctest -VV
> {code}
> This has two problems:
> * output is verbose even for successful tests, making it difficult to find errors in the log
> * tests are run serially even on a many-core machine
> I would suggest instead something like:
> {code}
> ctest -jN --output-on-failure
> {code}
> (where N is the available number of hardware threads / CPU cores)
