Ah, I see. So the problem is really that the library detection code
hasn't been written.
Hmm, having a look at the code, it seems that it should be fairly
simple to fix (but I'm not completely sure I understand the
interdependencies between setup.py, generate.py and addons.py, so I
don't dare creating a patch).
If the whole lapack section of addons was restructured like
set things up for using that path
use builtin blas_atlas
I think it would have the same functionality as now but without need
for the -use_lapack option.
OTOH I may be oversimplifying things, I have no idea how these
numerical libraries would normally be installed on Linux or other
unixen, let alone on Windows.
