Linker issue calling the D3DX10CreateEffectFromFile() method

Having issues trying to retrieve a effect file for directX. If I do not include the D3DX10CreateEffectFromFile() method, the application compiles correctly. If I do include it. I get the following error

1>GXDX.obj : error LNK2019: unresolved external symbol _D3DX10CreateEffectFromFileW@48 referenced in function "public: virtual void __thiscall GXDX::StartUp(struct HWND__ * *,int,int)" (?StartUp@GXDX@@UAEXPAPAUHWND__@@HH@Z)
1>C:\Users\numerical25\Desktop\Intro ToDirectX\GODFILES\GXRenderManager\GXRenderManager\Debug\GXRenderManager.exe : fatal error LNK1120: 1 unresolved externals

My first thought was maybe it is not linking the directx library correctly. But I find that to be off cause I am including the lib files and I am using other methods with no problem. below is my code.

header file

#ifndef GXDX_
#define GXDX_

#include "GXRenderer.h"
#include <d3d10.h>
#include <d3dx10.h>

below is the implementation

void GXDX::StartUp(HWND* mainWindow,int w, int h)

    width = w;
    height = h;
    this->m_mainWindow = mainWindow;

    //Get size of window

    if(FAILED(hr))
        throw GXVideoException(L"Problems retrieving directX device");

    hr = gm_swapChain->GetBuffer(0,__uuidof(ID3D10Texture2D), (LPVOID*)&backBufferSurface);

    if(FAILED(hr))

    hr = gm_dxDevice->CreateRenderTargetView(backBufferSurface, NULL,&gm_renderTargetView); 
    backBufferSurface->Release();

    if(FAILED(hr))
        throw GXVideoException(L"Failure to create Render Target View");
    

    //In the future, you might want to change this to something that allows multiple views
    //Like for an editor
    gm_dxDevice->OMSetRenderTargets(1, &gm_renderTargetView, NULL);

    UINT rectangle_width = rectangle.right - rectangle.left;

    };

        "fx_4_0",D3D10_SHADER_DEBUG,0,gm_dxDevice,NULL,NULL, &gm_shader,NULL,NULL);// Error here and dont know why

Gotta love linker errors. I mostly use DX9 at the moment, but I recall DX11 ditching effects (but still having them available). However, DX10 should still have them. Peeking through d3dx10async.h showed that the CompileEffectFromFile is still in there (June 2010 sdk), however. I noticed that the D3DX10CompileEffectFromFile is listed as deprecated in MSDN, with D3DX10CompileFromFile being its replacement. Double check your library links and try giving the D3DX10CompileFromFile function a shot (although theoretically if the CompileEffect func is still fully there and libraries are linked correctly it should work).

I guess the issue was that I didnt have the lib paths supplied in the additional lib directories under general in the solutions options area. I should of known that but it threw me off because any other method I called before this issue, worked fine.
