CMAKE_EXPORT_NO_PACKAGE_REGISTRY -------------------------------- Disable the :command:`export(PACKAGE)` command. In some cases, for example for packaging and for system wide installations, it is not desirable to write the user package registry. If the :variable:`CMAKE_EXPORT_NO_PACKAGE_REGISTRY` variable is enabled, the :command:`export(PACKAGE)` command will do nothing. See also :ref:`Disabling the Package Registry`.
