# Note that this test builds a special results.<pid> directory in
# which to run the tests, where <pid> is the process id number of
# the bash shell instance.  The reason for doing this is so that
# it works correctly under Github actions. By empirical
# observation, it appears that the various workflow matrix
# elements are not running in isolation when using cmake.  Rather
# they appear to be running simultaneously while sharing the build
# directory for cmake.  By running the tests in a separate
# results.<pid> I can guarantee that isolation is preserved.
