From 8b0d3f1ea4e0079f2efe4ba70e700af7eeebf989 Mon Sep 17 00:00:00 2001 From: Greg Bedwell Date: Wed, 11 Mar 2015 14:26:29 +0000 Subject: [PATCH] [CMake] Don't pass in MSVC warning flags as definitions NFC currently but required as a prerequisite for using the Microsoft resource compiler in conjunction with CMake's ninja generator, which knows how to filter flags appropriately, but not definitions.
