|
:command:`ExternalProject_Add` with ``GIT_SUBMODULES ""`` initializes no
|
|
submodules. The policy also applies to :command:`FetchContent_Declare`,
|
|
which uses the same download and update features as
|
|
:command:`ExternalProject_Add`.
|
|
|
|
The commands provide a ``GIT_SUBMODULES`` option which controls what submodules
|
|
to initialize and update. Starting with CMake 3.16, explicitly setting
|
|
``GIT_SUBMODULES`` to an empty string means no submodules will be initialized
|
|
or updated.
|
|
|
|
This policy provides compatibility for projects that have not been updated
|
|
to expect the new behavior.
|
|
|
|
The ``OLD`` behavior for this policy is for ``GIT_SUBMODULES`` when set to
|
|
an empty string to initialize and update all git submodules.
|
|
The ``NEW`` behavior for this policy is for ``GIT_SUBMODULES`` when set to
|
|
an empty string to initialize and update no git submodules.
|
|
|
|
This policy was introduced in CMake version 3.16. Use the
|
|
:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
|
|
Unlike most policies, CMake version |release| does *not* warn
|
|
when this policy is not set and simply uses ``OLD`` behavior.
