It uses CMake 3.16 built-in utilities to speed up build time: * Unity builds * Precompiled headers The feature is controlled via `ENABLE_FASTER_BUILD` CMake option (disabled by default). The option avaialble only on CMake >= 3.16. The feature is enabled per-target via `ie_faster_build` function. Some observations: * Don't have actual numbers for compile time, but subjectively can see speed up locally with VS 2019. * Unity builds gives much more effect, but has some restriction on source files, so are not used everywhere.
