C++ Unresolved External Symbols Embedded Lua

I am trying to make a game with Visual C++ 2010 with an embedded Lua engine, but I keep running into persistent unresolved external symbol errors. I put copies of all the files in the 'include' folder in the project headers folder, and I tried setting the linker library path to the Lua lib folder, as well as setting the include path to the Lua include folder, but I still am getting errors stating that the usage of a couple of Lua core functions are unresolved. I already tried quite a few solutions posted around the internet and each of which resulted in the same errors.

Output:

1>Main.obj : error LNK2019: unresolved external symbol _lua_pcall referenced in function _main
1>Main.obj : error LNK2019: unresolved external symbol _luaL_loadfile referenced in function _main
1>Main.obj : error LNK2019: unresolved external symbol _luaL_newstate referenced in function _main

Main.cpp:

#include "stdafx.h"
#include "Bubble Wars.h"

extern "C" {
#include "lua.h"
#include "lualib.h"
#include "lauxlib.h"
#include "luaconf.h"
#include "lua.hpp"
}

int main()
{
    lua_State * L = lua_open();
    luaL_dofile(L,"C:/Users/Trevor/Documents/Visual Studio 2010/Projects/Bubble Wars/Bubble Wars/Main.lua");
    return 0;
}

Main.cpp is the only source file that contains any Lua references. Any reasons for the function references to be unresolved?

Next to setting the linker directory, you also need to provide the actual libraries to link against to your linker.
