VD including libraries

[Prudence via Digitalmars-d-ide]

I have two projects in a solution. One is a test project and the 
other is the main project with several modules in several 
sub-dirs included that I use as a "library".

In the test project, how do I include references to the library 
so I can test specific library features without disturbing the 
main project? I've tried messing with the properties and adding 
the corresponding paths but the test project never finds the 
modules. Of course, the exact same code works in the main project.

Does VD ignore the library files and library paths?

I'm simply going to make a junction and use that as the link, but 
I'd prefer not to.
