[CMake] Support OpenBLAS in FindBLAS module

[Jean-Christophe Fillion-Robin]

Hi Xianyi,

By updating FindBlas.cmake, did you mean that the module should try to find
OpenBlas if it could not find any other implementation ? Or do you want to
provide an easy for developer to import the OpenBlas library in their
project ?

Either way, as described by Eike, the first step would be to update your
project so that it can create a OpenBlasConfig.cmake. See [1] for some
documentation

With such a file, it would then be possible for developer to do something
like:

           find_package(OpenBlas)

.. and have the CMake targets available in the current scope.

Let us know if you have any questions,
Jc
