Disable an Embree4 build warning

When included, the Embree4 rtcore_common.h header causes a compile-time
warning due to an enumerator value that exceeds the range of an int.
Note that this warning is silently disabled if this header is in a
directory defined by the '-isystem' option in gcc. And this is what
CMake does when the pkgconfig file uses the -I option rather than
-isystem. This is why this warning was not visible when using CMake.
