Put it in the optional packages list. Then check explicitly that it was
found in the sp2m configure method.

  Thanks,

I think I like the former option better. For those more familiar with BuildSystem than I am, I think I can do this by putting the following in setupDependencies() in mkl_sparse_sp2m.py:

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
