We are just setting up a Build Controller at work for our projects. Our projects depend on the DLLs from another application that is installed on the end-user's machine. I don't want to install that application on the build server unless I have to. To that end, I have tried placing the DLLs that I need into the custom assemblies folder, but MSBuild is unable to locate them from there.

Can I use the custom assemblies folder for any DLLs that my project needs, or is it only for DLLs that the build process needs? (i.e. NUnit, StyleCop)
