cmake policy CMP0043 on COMPILE_DEFINITIONS_<Config> properties

From bruen...@google.com on November 02, 2014 14:12:47

cmake 3.0.2 (maybe earlier too?) complains:

CMake Warning (dev) in ext/drgui/CMakeLists.txt: Policy CMP0043 is not set: Ignore COMPILE_DEFINITIONS_ properties. Run "cmake --help-policy CMP0043" for policy details. Use the cmake_policy command to set the policy and suppress this warning. This warning is for project developers. Use -Wno-dev to suppress it.
