From 91012d9af758a48c4c57fc940dfcc8a581fa46ac Mon Sep 17 00:00:00 2001 From: Dimitri Staessens Date: Wed, 14 Feb 2018 13:55:00 +0100 Subject: build: Allow out-of-tree build of tools This removes the dependencies for the tools on some ouroboros internal headers (endian.h and time_utils.h) so they can be built out-of-tree. The echo-app tool has been renamed oecho and the cbr tool has been renamed ocbr.
