Currently used build:
premake 5.0.0-alpha10

There are 3 supported build toolchains:
- Visual C++ on Windows x64 and x86
- GCC or Clang on Linux x64
- Clang or GCC on FreeBSD x64

@TODO: prevent UNICODE and _UNICODE from being #define'd with premake
@TODO: enable Minimal Rebuild from premake (instead of adding /Gm)
