From b18b84df5eab9829ecbef644ef0af226becf881d Mon Sep 17 00:00:00 2001 From: Daniel Hahler Date: Mon, 30 Sep 2019 00:10:29 +0200 Subject: build: run git-describe for dev version during build (#11117) This avoids invoking CMake after a new commit, which might take 15s on some systems. Skipped on CMake < 3.2.0 (missing BYPRODUCTS support). Co-Authored-By: Justin M.
