[Feature Request] add `-O2` or `-O3` optimize flag #756

Summary

Currently CMake files don't contain a -O2 or -O3 optimize flag (I am not sure which is better). Maybe we should add it when compiling for production.

By default the CMAKE_BUILD_TYPE is release, by default -O3 is included in CMAKE_BUILD_TYPE_RELEASE, see the link
