VS2008 and VS2010 Adding addons

Hi,
I am new in OF and am using both VS2008 and VS2010 and When I am creating my own application using the emptyExample project everything is working fine, but when I want to use extra Addons like ofxbox2x for example or shared source code by other developers I can’t compile it correctly with considering that I solved the dependencies problem like error:“cannot open directory” but then I faced Linking errors like

1>------ Build started: Project: emptyExample, Configuration: Debug Win32 ------

So plz would you help showing the whole steps to create this kind of projects without errors from A to Z.
