Dependency detecting for mixed mode C++ dll's.

Hi,
I have built a managed C++ library that is a wrapper for some
straight C++ dll's. The path in my program is C# project -> C++ mixed
mode class library -> C++ DLL's, and it works just fine.

I'm now creating a setup project for this. When I add the primary
output of the C# project it corrected detects the C++ mixed mode class
library dependency. However, it doesn't detect the C++ DLL's as a
dependency: I have to add them to the setup project by hand. Is there
a way to automate this?

One reason this is a pain is I develop on several different
machines, and the C++ DLL's are located in different locations. The
..NET setup project, however, records absolute paths to all the dll's
(relative would be much better).

Thanks in advance for any suggestions.

Cheers,
Gordon.
