Alternatively, you can set the environment variable LD_LIBRARY_PATH to point to the folder that contains libopenblas.so. Otherwise, linking at runtime will fail with a message like `cannot open shared object file: no such file or directory`
 
 If the library is multithreaded, please add `-lpthread`. If the library contains LAPACK functions, please add `-lgfortran` or other Fortran libs, although if you only make calls to LAPACKE routines, i.e. your code has `#include "lapacke.h"` and makes calls to methods like `LAPACKE_dgeqrf`, `-lgfortran` is not needed.
