Martin Šach 21116995d7 Refactor CMake and improve #includes.
* 1. Remove all global include_directories.
* 2. Move 3d party dependencies from src to budled deps if possible.
* Unify and enforce one way of including headers:
    e.g. #include "libslic3r/GCode.hpp" vs #include "GCode.hpp"
    (always use the "libslic3r/GCode.hpp" option).
* Make all dependencies (also header only) a cmake target.
