umpy``) searches for BLAS and
       LAPACK dynamic link libraries at build time as influenced by
       environment variables NPY_BLAS_LIBS, NPY_CBLAS_LIBS, and
       NPY_LAPACK_LIBS; or NPY_BLAS_ORDER and NPY_LAPACK_ORDER;
       or the optional file ``~/.numpy-site.cfg``.
       NumPy remembers those locations and expects to load the same
       libraries at run-time.
       In NumPy 1.21+ on macOS, 'accelerate' (Apple's Accelerate BLAS
       library) is in the default build-time search order after
       'openblas'.
