Your complaint about the slow compilation times might be addressed partially by Modules, expected for C++20. VS 2015 Update 1 and Clang already have experimental support.

in my experience when testing the current modules implementation, PCHs are still a good deal faster; if you use CMake they are dead easy to set-up so you may as well use them today.

Modules help, but you're still trucked if you change an underlying header.
