| CMAKE_EXPORT_NO_PACKAGE_REGISTRY |
| -------------------------------- |
| |
| Disable the :command:`export(PACKAGE)` command when :policy:`CMP0090` |
| is not set to ``NEW``. |
| |
| In some cases, for example for packaging and for system wide |
| installations, it is not desirable to write the user package registry. |
| If the ``CMAKE_EXPORT_NO_PACKAGE_REGISTRY`` variable is enabled, |
| the :command:`export(PACKAGE)` command will do nothing. |
| |
| If :policy:`CMP0090` is set to ``NEW`` this variable does nothing, and the |
| :variable:`CMAKE_EXPORT_PACKAGE_REGISTRY` variable controls the behavior |
| instead. |
| |
