# COMPONENTS can be some of the following:
# - MKL: to detect the FFTW from Intel MKL
# - ESSL: to detect the FFTW from IBM ESSL
# - THREADS: to detect the Threads version of FFTW
# - OMP: to detect the OpenMP version of FFTW
# - SIMPLE: to detect the FFTW simple precision fftw3f
# - DOUBLE: to detect the FFTW double precision fftw3 (default)
