Are there any guidelines how to use MKL on the one hand and use an
"external" FFTW3 on the other hand?
I found in src/pw/fft/fftw3_lib.F following line, which gives me the
impression it's maybe not that simple to decouple MKL and MKL's FFT.
#if defined (__INTEL_COMPILER) && defined (__MKL) && defined (__FFTW3)
