The LFLAGS simply specifies the path of the libraries

The IPPLIBS specifies which specific libraries to link according to the CPU 
architecture being used.

That is not the issue here. I have the correct path and I am linking the 
generic dll stub lib that covers all architectures (ippcore and ippi).

The problem appears to be with __stdcall and __cdecl conventions.

The linker is complaining about a missing function called 
`ippiDCT8x8Fwd_16s_C1I at 4'. I think it should be looking 
for '_ippiDCT8x8Fwd_16s_C1I at 4'

Is that not right?
