Runs all (matching) performance-test programs

$ScriptPath [ ... flags/options ... ]

Flags/options:

    behaviour:

    --expand-width <expand-width>
        subjects each performance test program's output to expand with the
        given <expand-width>

    --gap-groups
        sets SIS_PERFTESTS_GROUPGAPS=1 so performance programs emit a blank
        line between scenario groups on a TTY, or a visible `\t----------`
        rule when stdout is not a TTY (e.g. CI)

    -l
    --list-only
        lists the target programs but does not execute them

    -M
    --no-make
        does not execute CMake and make before running tests


    standard flags:

    --help
        displays this help and terminates

EOF
