This CommandLineArguments is to do with passing in arguments to compiled executables. scons used to have an option to "build and run with these command line arguments to the test/executable" but I guess that would now be something to do with ctest if that can actually do it?

For this to be sorted we want to give advice on how to pass command line arguments to a test executable at the time you write ctest TestBlah....

Some stackoverflow here that looks very complicated! https://stackoverflow.com/questions/28812533/how-to-pass-command-line-arguments-in-ctest-at-runtime

Alternatively, we don't ever do this anymore as you can manually run the test executable and do it directly?
