# -------------------------
#
# ::
#
# find_dependency(<dep> [<version>])
#
#
# ``find_dependency()`` wraps a :command:`find_package` call for a package
# dependency. It is designed to be used in a <package>Config.cmake file, and it
# forwards the correct parameters for EXACT, QUIET and REQUIRED which were
# passed to the original :command:`find_package` call. It also sets an
# informative diagnostic message if the dependency could not be found.
