From a4d17b34f354557838e05d2cb47200e8dcaaf59b Mon Sep 17 00:00:00 2001 From: Bill Roberts Date: Tue, 9 Jan 2024 13:10:05 -0600 Subject: [PATCH] pkg-config: add initial pkg-config files Add three package config files for mbedtls, mbedcrypto and mbedx509. Also update various project variables so the generated PC files have the required data needed without hardcoding it everywhere. This will help distros package the project following existing conventsions between a normal and -devel package that includes the headers and .pc files for pkg-config aware consumers.
