> Currently the default {{test}} target runs serially while {{unittest}} arbitrarily uses 4 threads. On many systems that's suboptimal. The environment variable {{CTEST_PARALLEL_LEVEL}} can be set to run tests in parallel, and we should probably have a good default for it (like the hardware concurrency)
