Linking on Debian: libblas instead of libcblas

[Chris00]

I use ndarray-linalg with the feature netlib-system. When compiling I get

  = note: /usr/bin/ld: cannot find -lcblas: No such file or directory
          collect2: error: ld returned 1 exit status

On Debian, the file /usr/share/doc/libblas-dev/README.if-you-look-for-libcblas.so.3 says

lapack (3.8.0-8) unstable; urgency=medium

• README if you look for libcblas.so

  Debian science team maintainers have merged the CBLAS ABI into
  the libblas.so shared object. Everything you need from libcblas.so
  can be found in libblas.so . Please link your program against it
  instead. See also

  This README file has an unusual name because we expect users to
  find it by this way:

  $ apt-file search libcblas
  /usr/share/doc/libblas-dev/README.if-you-look-for-libcblas.so
  /usr/lib/...

A simple workaround is to make symlinks libcblas → libblas but it would be better if this package appropriately configured the names of the library.
