Create actions for automatic build for windows, linux & mac

but i don't know how to create a good package for mac. A zip with the exe is enough?

restrict cmake MAP_IMPORTED_CONFIG_RELWITHDEBINFO to windows only.
missing #include <numeric> & <boost/log/trivial.hpp> & "libslic3r/PrintConfig.hpp" in some files for macos to compile
