Utility functions used by multiple files.
.. cmake:command:: dune_module_to_uppercase
Convert a module name into an uppercase string.
.. code-block:: cmake
dune_module_to_uppercase(<upper> <module>)
Convert a module name given by ``<module>`` parameter into an uppercase
string stored in the output variable ``<upper>`` where all dashes ``-``
are replaced by underscores ``_``.
Example: ``dune-common -> DUNE_COMMON``
.. cmake:command:: dune_module_to_macro
Convert a module name into a capitalized string.
.. code-block:: cmake
dune_module_to_macro(<macroname> <module>)
Convert a module name given by ``<module>`` into a string stored in the
output variable ``<macroname>`` where all dashes ``-`` are removed and the
first letter and all letters following a dash are capitalized.
Example: ``dune-grid-howto -> DuneGridHowto``
.. cmake:command:: dune_deprecate_variable
Writes a deprecation message on a variable read access. This is intended to be
called by ``variable_watch(....)``.
