CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY
--------------------------------------

.. versionadded:: 3.1

.. deprecated:: 3.16

  Use the :variable:`CMAKE_FIND_USE_PACKAGE_REGISTRY` variable instead.

By default this variable is not set. If neither
:variable:`CMAKE_FIND_USE_PACKAGE_REGISTRY` nor
``CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY`` is set, then
:command:`find_package()` will use the :ref:`User Package Registry`
unless the ``NO_CMAKE_PACKAGE_REGISTRY`` option is provided.

``CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY`` is ignored if
:variable:`CMAKE_FIND_USE_PACKAGE_REGISTRY` is set.

In some cases, for example to locate only system wide installations, it
is not desirable to use the :ref:`User Package Registry` when searching
for packages. If the ``CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY``
variable is ``TRUE``, all the :command:`find_package` commands will skip
the :ref:`User Package Registry` as if they were called with the
``NO_CMAKE_PACKAGE_REGISTRY`` argument.
