 LAPACKE Backend

 Currently three LAPACKE implementations are supported and tested:
 
 - [OpenBLAS](https://github.com/cmr/openblas-src)
+  - needs `gfortran` (or other Fortran compiler)
 - [Netlib](https://github.com/cmr/netlib-src)

 - [Intel MKL](https://github.com/termoshtt/rust-intel-mkl) (non-free license, see the linked page)

 There are two ways to link LAPACKE backend:
