| :command:`export(PACKAGE)` does not populate package registry by default. |
| |
| In CMake 3.14 and below the :command:`export(PACKAGE)` command populated the |
| user package registry by default and users needed to set the |
| :variable:`CMAKE_EXPORT_NO_PACKAGE_REGISTRY` to disable it, e.g. in automated |
| build and packaging environments. Since the user package registry is stored |
| outside the build tree, this side effect should not be enabled by default. |
| Therefore CMake 3.15 and above prefer that :command:`export(PACKAGE)` does |
| nothing unless an explicit :variable:`CMAKE_EXPORT_PACKAGE_REGISTRY` variable |
| is set to enable it. This policy provides compatibility with projects that |
| have not been updated. |
| |
| The ``OLD`` behavior for this policy is for :command:`export(PACKAGE)` command |
| to populate the user package registry unless |
| :variable:`CMAKE_EXPORT_NO_PACKAGE_REGISTRY` is enabled. |
| The ``NEW`` behavior is for :command:`export(PACKAGE)` command to do nothing |
| unless the :variable:`CMAKE_EXPORT_PACKAGE_REGISTRY` is enabled. |
