ls -la /usr/lib64/libcblas.so
lrwxrwxrwx 1 root root 26  2 jun 13:44 /usr/lib64/libcblas.so ->
blas/reference/libcblas.so

ls -la /usr/lib64/libblas.so
lrwxrwxrwx 1 root root 25  2 jun 13:43 /usr/lib64/libblas.so ->
blas/reference/libblas.so

ls -la /usr/lib64/liblapack.so
lrwxrwxrwx 1 root root 29  2 jun 13:47 /usr/lib64/liblapack.so ->
lapack/reference/liblapack.so
