Overall LGTM. I have few questions I want to get clarity on.

In other words, when compiling for the host, we will let the compiler decide the best options?

In other words, when cross-compiling, we will have to specify certain CMake vars explicitly?

Does it mean that benchmarks are always compiled for the host?
