I checked scipy detection code … it has a special case for blas=blas
and sets cblas=cblas then. When we set blas=cblas, this results in
blas=cblas and cblas=cblas, or something like that … and direct libblas
usage is broken.

So the hotfix is to request C api, but have it use libcblas implicitly.
This only works as long as we only have netlib with separate CBLAS lib.
For openblas variants, it does not matter.


Alrighty then,

Thomas
