DuneStreams
===========

Configuration helpers for the DUNE debug streams.

.. cmake:command:: dune_set_minimal_debug_level

  Initialize the cache variables controlling the built-in DUNE debug streams.

  .. code-block:: cmake

    dune_set_minimal_debug_level()

  The command maps the textual cache value in
  :cmake:variable:`MINIMAL_DEBUG_LEVEL` to the numeric preprocessor value
  ``DUNE_MINIMAL_DEBUG_LEVEL`` used by the C++ debug stream implementation.

.. cmake:variable:: MINIMAL_DEBUG_LEVEL

  Minimal enabled DUNE debug stream level. Streams below this level collapse
  to no-ops when output is requested.

  Supported values are ``vverb``, ``verb``, ``info``, ``warn``, and
  ``grave``. The default is ``warn``.
