add_dependencies
|
|
|
|
|
----------------
|
|
|
|
|
|
|
|
|
|
Add a dependency between top-level targets.
|
|
|
|
|
|
|
|
|
|
.. code-block:: cmake
|
|
|
|
|
|
|
|
|
|
add_dependencies(<target> [<target-dependency>]...)
|
|
|
|
|
|
|
|
|
|
Makes a top-level ``<target>`` depend on other top-level targets to
|
|
|
|
|
ensure that they build before ``<target>`` does. A top-level target
|
|
|
|
|
is one created by one of the :command:`add_executable`,
|
|
|
|
|
:command:`add_library`, or :command:`add_custom_target` commands
|
|
|
|
|
(but not targets generated by CMake like ``install``).
|
|
|
|
|
|
|
|
|
|
Dependencies added to an :ref:`imported target <Imported Targets>`
|
|
|
|
|
or an :ref:`interface library <Interface Libraries>` are followed
|
|
|
|
|
transitively in its place since the target itself does not build.
|
|
|
|
|
|
|
|
|
|
.. versionadded:: 3.3
|
|
|
|
|
Allow adding dependencies to interface libraries.
|
|
|
|
|
|
|
|
|
|
.. versionadded:: 3.8
|
|
|
|
|
Dependencies will populate the :prop_tgt:`MANUALLY_ADDED_DEPENDENCIES`
|
|
|
|
|
property of ``<target>``.
|
|
|
|
|
|
|
|
|
|
.. versionchanged:: 3.9
|
|
|
|
|
The :ref:`Ninja Generators` use weaker ordering than
|
|
|
|
|
other generators in order to improve available concurrency.
|
|
|
|
|
They only guarantee that the dependencies' custom commands are
|
|
|
|
|
finished before sources in ``<target>`` start compiling; this
|
|
|
|
|
ensures generated sources are available.
