From dc20371f83ed81462c0b24eb750b76f7819df64a Mon Sep 17 00:00:00 2001 From: Oliver Giles Date: Thu, 5 Dec 2019 23:37:36 +0200 Subject: build: export vapi generation in vpp-dev Adds the higher-level vapi generation to cmake/api.cmake and exposes the necessary python scripts in vpp-dev, so that out-of-tree/downstream plugins can also leverage the more convenient API.
