[petsc-users] [petsc-dev] mkl-cpardiso configuration

[Satish Balay]

If one specifies '--with-mkl=/foo/bar --download-f-blas-lapack' or
just '--with-mlk=/foo/bar' where configure picks up /usr/lib/libblas.a
etc - then things will break.

So somehow these two options should work together - and perhaps the
way they can do is within blaslapack.py [and not a separate mkl.py]

I've been trying to modify my mkl.py file to achieve this, however your configuration system is a little bit complex, so if you code give some guidelines to achieve this or files to look how to do it would be great.
