Active Directory notifications - c++

Question

I have seen this example documented by microsoft, but cannot get it to work in visual studio 2012, under a console project.
https://msdn.microsoft.com/en-us/library/ms676877(v=vs.85).aspx
Is there something I am missing, ie. is a console application correct.
The Errors I get are:
Error 1 error LNK2019: unresolved external symbol __imp__ldap_openW referenced in function "int __cdecl GetChangeNotifications(wchar_t *)" (?GetChangeNotifications##YAHPA_W#Z) C:\projects\AD_Notifications\AD_Change_Notifications\AD_Change_Notifications\AD_Change_Notifications.obj AD_Change_Notifications
From what I have been reading its a linker error, which is kinda obvious, but it is all in 1 file, so I don't understand what I am suppose to be linking?

The best answer I found in java is quoted below from https://community.oracle.com/thread/1158217
