+  Instead of loading the outside project's cache file and manually accessing
+  variables, a more robust and convenient approach is to use the
+  :command:`export` command in the outside project, when available.  This allows
+  the project to provide its targets, configuration, or features in a
+  structured and maintainable way, making integration simpler and less
