LAPACK sneakily added a massive update in the 3.12.1 "bugfix" release. This made LAPACKE get build with requirement on _64 suffixed ilp64 symbols.

Flexiblas doesn't support these at all, so, which means LAPACKE from this flexiblas is completely useless; linking to flexiblas isn't sufficient.

This is currently breaking testing in my LAPACK++ PR #24135 because of these unresolved symbols, rendering -llapacke linking broken.
