How do I merge multiproject docs? Is that currently possible? We're using 1.4.30.
If not, is there a workaround? In older versions of dokka it was possible to add external files to the classpath, but It is not clear to me how I could do that in the newer dokka rewrite. Especially if I still want the modules from the composite project to appear as modules in the merged dokka documentation?

It would already help if it was possible to just add the sources of the secondary project to the dokka classpath of the parent project.
