+# Due to the interaction between BLAS and LAPACK, we need to choose implementations consistent with
+# each other.
+#
+# First, if we are on Apple, we use the Accelerate framework.
+#
+# Then, we prefer to use openblas and lapack-reference for blas and lapack, respectively, but
+# sometimes are unable.
+#
+# If we are on Windows and arm or uwp, that we use gfortran as our fortran compiler creates an issue
+# because there is no available libgfortran. This means ew can't use lapack-reference at all.
+#
+# If we are on Windows and static, there is a linking problem caused by static gfortran in the same
+# link as openblas, so we have to use the blas implementation from lapack-reference.
+#
+# That results in roughly the following decision tree:
+#
+# no_libgfortran = (uwp || (windows && arm))
+# can_link_mixed_static_libgfortran = !windows || !static
+#
+# if (no_libgfortran) {
+#    return {

+#         "lapack": "lapack-reference[blas]"

+#
+# Scoping this to just the 'can use openblas' question, we get:
