How to include a common dll repository that can be used by many of the projects in the multi project template based VSIX installer

Hi,

I am creating a new VSIX extension. Once installed, I will create few projects [class library & web application] I have to share some of the dll files between these projects. I have updated the project files to refer to the dlls by using ..\ in their references.

I am not able to find a way to add the dll files in a folder that is not a project using the vstemplate. Kindly guide me through the necessary steps.
