DuneDoc
-------

Documentation helper commands used by dune-common.

This module provides the top-level ``doc`` target together with helper commands
used to build and install generated documentation files.

.. cmake:command:: dune_add_latex_document

  Wrapper around ``add_latex_document()`` for compatibility reasons.

  .. code-block:: cmake

    dune_add_latex_document(<args...>)


.. cmake:command:: create_doc_install

  Create a target for building and installing a generated documentation file.

  .. code-block:: cmake

    create_doc_install(<filename> <targetdir> <dependency>)

  ``filename``
    The name of the file to be installed.

  ``targetdir``
    The directory into which the file is installed.

  ``dependency``
    The target that creates the file before installation.

  This helper is needed because dependencies cannot be attached directly to the
  install target. See the related CMake issue
  ``https://gitlab.kitware.com/cmake/cmake/issues/8438`` and the DUNE issue
  ``https://gitlab.dune-project.org/core/dune-common/issues/36``.
