| CTEST_CHANGE_ID | |
| --------------- | |
| .. versionadded:: 3.4 | |
| Specify the CTest ``ChangeId`` setting | |
| in a :manual:`ctest(1)` :ref:`Dashboard Client` script, | |
| or on the :program:`ctest` command line via the :ref:`-D <ctest-option-D-var>` option. | |
| This setting allows CTest to pass arbitrary information about this | |
| build up to CDash. One use of this feature is to allow CDash to | |
| post comments on your pull request if anything goes wrong with your build. |
