Unresolved externals - Please help!

[poworoznyk]

I have 2 projects

p1:
GestureDLL.cpp

p2:
Main.h
Main.cpp

I am trying to call functions from p1 so that I can export them in the DLL from p2. I have added additional dependecies to the folder where Main.h lies, but am still recieving the error. Could someone please help!!
