<div>I was trying to build petsc using MKL blas/lapack and had a small issue. I tried to point configure at the mkl directory with --with-blas-lapack-dir, but it found an installation of ATLAS already in /usr/local/lib and used that instead. </div>

<br>
Is there any way to force a specific flavor of BLAS in a flag passed to configure (I mean, so I don't have to modify BlasLapack.py, which is what I did). Or alternatively, is there a way to force the issue by using --with-blas-lapack-lib, --with-blas-lib? I wasn't able to figure out the correct incantation to include all of the stuff MKL needs to link against.</div>
