Bear in mind that nothing in GRASS actually uses BLAS or LAPACK at
present. More precisely, the gmath library provides additional
functions (see src/libes/gmath/la.c) if BLAS and LAPACK are present,
but nothing uses those functions.

GRASS' fft() function (src/libes/gmath/fft.c) uses the FFTW library.
