compat.openblas
#includeOpenBLAS — optimized BLAS, built from source (BLAS-only, no Fortran/LAPACK)

Curated in .xpkgindex/interfaces.json.
mcpp add compat.openblas@0.3.33
Usage
From this repository's own test project — built and run by CI, not written for the website.
// On Windows the cfg-gated openblas dep + HAVE_OPENBLAS are active: cblas_dgemm
// asserting [19 22; 43 50]. Elsewhere a no-op (openblas is Windows-only).

#include <cblas.h>
