Travis doesn't work for multi-node tests

[CamStan]

Currently, the way tests are set up for some of the components, adding a test requires the number of nodes be dictated:

ADD_TEST(NAME shuffile_test COMMAND ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} 6 -N3 -m block ./shuffile_test)
                                                                         ^^^

This causes the tests to fail as -N is not recognized.

This is currently an issue with:

• shuffile
• redset

Thank you, Cameron. Do you know the solution for that? Greg

I do not. I don't think there was a CMake envar for it. The tests will still be run by GitLab, so might not be a big deal. Just wanted to make note of it somewhere since I'd already forgotten about shuffile until I saw the same thing in redset.
