.. code-block:: cmake
ctest_run_script([NEW_PROCESS] script_file_name script_file_name1
script_file_name2 ... [RETURN_VALUE var])
Runs a script or scripts much like if it was run from :option:`ctest -S`.
If ``NEW_PROCESS`` is specified then each script will be run in a separate
process. If ``RETURN_VALUE`` is specified the return value of the last script
run will be put into ``var``.
