+By default Ninja (package:devel/ninja[]) is used for the build. In some cases this does not work correctly. With the `noninja` argument, the build will use regular `make` for builds. This argument should only be used if a Ninja-based build does not work.
 
 With the `run` argument, a run dependency is registered in addition to a build dependency.
 
+With the `testing` argument, a test-target is added that uses CTest. When running tests the port will be re-configured for testing and re-built.
