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.

* The ``DEPENDS`` option of :command:`add_custom_target` and
:command:`add_custom_command` commands for adding file-level
dependencies in custom rules.
* The :prop_sf:`OBJECT_DEPENDS` source file property to add
file-level dependencies to object files.
