1CMAKE_EXPORT_PACKAGE_REGISTRY
2-----------------------------
3
4.. versionadded:: 3.15
5
6Enables the :command:`export(PACKAGE)` command when :policy:`CMP0090`
7is set to ``NEW``.
8
9The :command:`export(PACKAGE)` command does nothing by default.  In some cases
10it is desirable to write to the user package registry, so the
11``CMAKE_EXPORT_PACKAGE_REGISTRY`` variable may be set to enable it.
12
13If :policy:`CMP0090` is *not* set to ``NEW`` this variable does nothing, and
14the :variable:`CMAKE_EXPORT_NO_PACKAGE_REGISTRY` variable controls the behavior
15instead.
