If I understand correctly, Project label get used to create sln files,
but otherwise aren't used for anything.  This means that actually what I
had wasn't wrong, as I would generate a Project.sln and a Project.vcproj
in my Project/ subdirectory - this sounds reasonable to me.

I've got that.  However, the .sln file doesn't appear to reference the
.vcproj files for objects specified in the target_link_libraries.  I
would expect these to get added too.

So, for your (modification of my) example above, the Project.sln file
will have a link to ProjectLib.vcproj, but it should also have a link to
Library.vcproj (in whatever directory it lives in) to be a complete
solution.  It doesn't appear from my experimentation that this works -
or otherwise something I'm doing is breaking it.

That I understand, however the sub-projects also want the linked
libraries added to their solutions.
Does that make sense, or am I smoking crack?
