Improve finding of BLAS libraries in macOS / Macports

Browse Source 
MacPorts' lapack is not guaranteed to produce libblas.dylib. For example if the +openblas variant is used, then lapack uses openblas.
This commit tries to find and use libopenblas.dylib if  libblas.dylib is not found.
Fixes usage of BLAS_ROOT
