CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY -------------------------------------- .. 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 :variable:`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. See also :ref:`Disabling the Package Registry`.
