From af2092060cf7092f077a20e4b67214523bdb026a Mon Sep 17 00:00:00 2001 From: Zachary Turner Date: Tue, 24 Feb 2015 23:32:47 +0000 Subject: [PATCH] [CMake] Set policy CMP0051 to OLD globally. When you use generator expressions in a library sources list, and then later access the SOURCES property, the OLD behavior (CMake 3.0 and earlier) would not include these expressions in the SOURCES property. The NEW behavior (starting in CMake 3.1) is that they do include the generator expressions in the SOURCES property.
