Raw Blame History

From 26c86195935f5365685bfefe046f0ac7e98fa231 Mon Sep 17 00:00:00 2001
From: Kimball Thurston <kdt3rd@gmail.com>
Date: Sat, 8 Sep 2018 18:09:01 +1200
Subject: [PATCH] fix standalone and combined cmake
This puts the version numbers into one file, and the settings and
variables for building into another, that is then replicated and
conditionally included when building a standalone package.
Signed-off-by: Kimball Thurston <kdt3rd@gmail.com>
