set -std=gnu++11 globally for C++ only 

Add -std=gnu+11 to CMAKE_CXX_COMPILE_OBJECT in the main CMakeLists.txt
to force the option for all C++ sources.

The right way to do this is to use a generator expression with
ADD_COMPILE_OPTIONS, but this is only available in cmake 3.3 and we must
maintain 2.8.12 compatibility to support Ubuntu 14.

This fixes the mac build (clang.)
