Bundle OpenBLAS and replace reference BLAS and LAPACK
BLAS library is crucial for optimizing MUMPS performance. OpenBLAS is widely used and I've been using it to compile MUMPS for many years. Lately it includes LAPACK in its source distribution, thus making redundant downloading and compiling separate sources. OpenBLAS is also released as binaries and can be downloaded and installed without need for compilation and seems like an appropriate addition/enhancement to the project. Before having a go at it, is there any particular reason for not bundling OpenBLAS? Costas
