- ctest_update
- ------------
- Perform the :ref:`CTest Update Step` as a :ref:`Dashboard Client`.
- ::
- ctest_update([SOURCE <source-dir>] [RETURN_VALUE <result-var>] [QUIET])
- Update the source tree from version control and record results in
- ``Update.xml`` for submission with the :command:`ctest_submit` command.
- The options are:
- ``SOURCE <source-dir>``
- Specify the source directory. If not given, the
- :variable:`CTEST_SOURCE_DIRECTORY` variable is used.
- ``RETURN_VALUE <result-var>``
- Store in the ``<result-var>`` variable the number of files
- updated or ``-1`` on error.
- ``QUIET``
- Tell CTest to suppress most non-error messages that it would
- have otherwise printed to the console. CTest will still report
- the new revision of the repository and any conflicting files
- that were found.
- The update always follows the version control branch currently checked
- out in the source directory. See the :ref:`CTest Update Step`
- documentation for more information.
