Linking problems while compiling and linking DFT.cpp

I have a cpp file here:

#include "stdafx.h"
#include "ipp.h"
#include "tools.h"

// Calculate FFT and extend CCS representation to full signal
void myDFT_RToC_32f32fc(Ipp32f* pSrc, Ipp32fc*pDst, int len)
{
	IppsDFTSpec_R_32f *pDFTSpec;
	ippsDFTInitAlloc_R_32f( &pDFTSpec, len, IPP_FFT_DIV_INV_BY_N,
		ippAlgHintFast );
	ippsDFTFwd_RToCCS_32f(pSrc, (Ipp32f*)pDst, pDFTSpec, 0 );
	ippsConjCcs_32fc_I(pDst, len);
	ippsDFTFree_R_32f(pDFTSpec);
}

int main(int argc, char* argv[])
{
	int len;
	Ipp32f* pSrc;
	Ipp32fc* pDst;
	Ipp32f* pDstMag;

	for (len=4; len<= 8192; len*=2)
	{
		// Generate a Jaehne signal as source for FFT
		pSrc = ippsMalloc_32f(len);
		pDst = ippsMalloc_32fc(len);
		pDstMag = ippsMalloc_32f(len);
		ippsVectorJaehne_32f( pSrc, len, 1 );

		// Take DFT, calculate magnitude, and display
		myDFT_RToC_32f32fc(pSrc, pDst, len);
		ippsMagnitude_32fc(pDst, pDstMag, len);
		spView_32f( pDstMag,len,"DFT(Source)", 1 );

		ippsFree(pDst);
		ippsFree(pSrc);
		ippsFree(pDstMag);
	}

	return 0;
}

(I am using icl.exe in windows 7)

When it is tried to link the DFT.obj file with the command xilink DFT.obj,

the following errors are coming:

DFT.obj

DFT.obj : error LNK2019: unresolved external symbol _ippsFree@4 referenced in function _main

What could be the reason for this error message.

I which library _ippsMalloc_32f is defined?

How can I find which function is defined in which library?
