From c52d731e5ef47a43f549d497883d39fccb2992a6 Mon Sep 17 00:00:00 2001
From: Thiago Macieira <thiago.macieira@intel.com>
Date: Tue, 11 Mar 2025 21:53:43 -0700
Subject: [PATCH] cbor.h: let tinycbor-export.h define CBOR_API

And make CBOR_PRIVATE_API fall back to it.

We also need to provide the file for the old Makefile build too.
