Headers and symlinks for what recipe?  This one?

Redundant, you can remove.

Redundant, remove.

Better to fix your makefile so it doesn't override LDFLAGS
assignments: your makefile is what is broken here.

That's the default, you can remove this.

You're not installing the headers or library symlinks, which is why
they're not in the SDK.

I suggest you move from raw makefiles to a build utility such as
autotools, cmake, or meson.
