 On BSD you should probably use GNU make right now. The Makefiles are simple enough however.
-Clang should also be supported, pass CC=clang and CXX=clang++ if you want to use it.

 On NT you'll probably have a build command-line likes this:
 `CC=x86_64-w64-mingw32-gcc CXX=x86_64-w64-mingw32-g++ PKG_CONFIG_PATH=/usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig make -j 4`
 Not all works yet, but stay tuned.
 
+It'll compile everything into a subdirectory 'build'. At the end it'll copy files from ./resources into it too.

+In the Nuclide SDK, build_engine.sh will call make with the appropriate flags for Linux/BSD automatically and
