I'm getting this error while trying to build Oregon Core:

LINK : fatal error LNK1104: cannot open file '..\shared\Debug\shared.lib'
LINK : fatal error LNK1104: cannot open file '..\..\collision\Debug\collision.lib'

Is it normal that I can't find shared.lib and collision.lib? There are no such files on my PC actually. I can't make a path to them if they don't exist. Does anyone have any idea why I'm missing them?
