The only package really relevant for user is libopenblas_dynamic
$ cygcheck -l libopenblas_dynamic
/usr/bin/cygblas-0.dll
the library is before the reference one in the path
$ cygcheck -l liblapack0|grep blas
/usr/lib/lapack/cygblas-0.dll
and used instead of.
Could this be done with alternatives instead and could we get rid of
/usr/lib/lapack and the need to have it in $PATH in the process, please?
unfortunately alternatives is not effective with dll's.
Windows ignores cygwin links.
My predecessor that was playing with ATLAS had the same issue
and used "/usr/lib/lapack" and PATH to solve the problem of multiple
alternative dll's with the same name.
