DuneModuleDependencies
----------------------
Macros to extract dependencies between Dune modules by inspecting the
``dune.module`` files.
.. cmake:command:: dune_create_dependency_tree
.. code-block:: cmake
dune_create_dependency_tree()
Create a tree of dune module dependencies by inspecting the ``dune.module``
files recursively.
.. cmake:command:: dune_process_dependency_macros
.. code-block:: cmake
dune_process_dependency_macros()
Include the corresponding ``Dune<module>Macros.cmake`` file of all
dependencies if this file exists.
