# Elk requires BLAS/LAPACK and fast Fourier transform (FFT) libraries.

# We recommend using optimised, mutithreaded BLAS/LAPACK libaries such as those
# provided by the Intel Math Kernel Library (MKL), OpenBLAS or BLIS.

# Elk can use either the Fastest Fourier Transform in the West (FFTW) or the
# MKL FFT. Both single and double precision versions of the FFT are needed.
