@ -589,6 +589,11 @@ Configuration settings to specify the version control tool include:
|
|||
* `CTest Script`_ variable: :variable:`CTEST_GIT_COMMAND`
|
||||
* :module:`CTest` module variable: ``GITCOMMAND``
|
||||
|
||||
The source tree is updated by ``git fetch`` followed by
|
||||
``git reset --hard`` to the ``FETCH_HEAD``. The result is the same
|
||||
as ``git pull`` except that any local moficiations are overwritten.
|
||||
Use ``GITUpdateCustom`` to specify a different approach.
|
||||
|
||||
``GITInitSubmodules``
|
||||
If set, CTest will update the repository's submodules before updating.
