CMakeFindDependencyMacro
-------------------------

.. command:: find_dependency

The ``find_dependency()`` macro wraps a :command:`find_package` call for
  a package dependency::

find_dependency(<dep> [...])

It is designed to be used in a
  :ref:`Package Configuration File <Config File Packages>`
  (``<PackageName>Config.cmake``).  ``find_dependency`` forwards the correct
  parameters for ``QUIET`` and ``REQUIRED`` which were passed to
  the original :command:`find_package` call.  Any additional arguments
  specified are forwarded to :command:`find_package`.

If the dependency could not be found it sets an informative diagnostic
  message and calls :command:`return` to end processing of the calling
  package configuration file and return to the :command:`find_package`
  command that loaded it.

.. note::

The call to :command:`return` makes this macro unsuitable to call
    from :ref:`Find Modules`.
