[C++]Unresolved external symbol

[PenguinGuy]

[Edit]
Apparently, I was using the wrong lib for x64 for SQLAPI.
Also, Detours 1.5 doesn't support x64, and you can't compile Detours 2.1 for x64 unless you have Detours Professional (wtf? it says it supports x64 lol).
[/Edit]

I'm trying to target my project to a x64 machine, changed the options and so forth.
However, even though I declare I'm using these libs, it keeps saying "External symbol" when compiling.

#pragma comment( lib, "SQLAPI.lib" )
#pragma comment( lib, "CDetour.lib" )

Am I missing something?
