+will be brought up-to-date whenever the target being declared is), and adds its
+usage requirements to the build properties of the target being declared. The
+dependency is not used in any other way. The primary use case is when you want
+the usage requirements (such as `#include` paths) of some library to be
+applied, but do not want to link to it.
