| 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`. |
