-# On RHEL and SUSE, we link R against the internal shared BLAS to make the
-# R binaries more portable and allow users to switch BLAS implementations without
-# having to recompile R. We default to OpenBLAS, but users may prefer other implementations.
-# 
-# Binary packages built against the shared BLAS are also more portable and may be used
-# with the default R distributed by RHEL/SUSE, or other R installations using
-# shared BLAS and configured with a different BLAS (such as Microsoft R Open with MKL).
-# This is especially important for Posit Package Manager's binary packages.
-#
-# However, EPEL 9's R now links externally against FlexiBLAS, which provides a
-# native BLAS switching mechanism for Fedora/RHEL. Starting with R 4.3.0, we also
-# link to external FlexiBLAS for compatibility.

-#
-# On Ubuntu/Debian, we link R against the external BLAS instead (--with-blas/--with-lapack),
-# as those distributions use the alternatives system to swap BLAS libraries at runtime.
-# The default R distributions on Ubuntu/Debian use the external BLAS, so we do as well
-# for portability.
