+Disabling the Package Registry
+------------------------------
+
+In some cases using the Package Registries is not desirable. CMake
+allows to disable them using the following variables:
+
+ * :variable:`CMAKE_EXPORT_NO_PACKAGE_REGISTRY` disables the
+ :command:`export(PACKAGE)` command.
+ * :variable:`CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY` disables the
+ User Package Registry in all the :command:`find_package` calls.
+ * :variable:`CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY` disables
+ the System Package Registry in all the :command:`find_package` calls.
