build configuration
Hi, I would like to know what is the configuration you use in compiling numpy. I have several blas libraries (openblas, mkl and the system blas) I am able to build numpy against any with site.cfg but I am not able switch the backend on the fly with update-
However the python3-numby package from Ubuntu can switch on the fly! I am wondering how you do that. (if I don't use a site.cfg then numpy would be compiled against the system blas aka the slow one)
I tried install with pip install --no-binary numpy numpy in ~/.local. tried the same version as in the repo (1.21.5, Ubuntu 22.04)
Thanks.
