if Scipy requires just a BLAS, liblapack-devel  should be enough for
the compilation.

libopenblas for compatibility reason provides only the shared library
but I am not packing the headers. It helps to run faster any BLAS
routine used by programs.

ATLAS takes too long to compile and it does NOT provides multiprocessor
libraries as OpenBlas. So no interest to package it for Cygwin from
my side.
