CMAKE_EXPORT_PACKAGE_REGISTRY ----------------------------- Enables the :command:`export(PACKAGE)` command when :policy:`CMP0090` is set to ``NEW``. The :command:`export(PACKAGE)` command does nothing by default. In some cases it is desirable to write to the user package registry, so the ``CMAKE_EXPORT_PACKAGE_REGISTRY`` variable may be set to enable it. If :policy:`CMP0090` is *not* set to ``NEW`` this variable does nothing, and the :variable:`CMAKE_EXPORT_NO_PACKAGE_REGISTRY` variable controls the behavior instead. See also :ref:`Disabling the Package Registry`.
