I don't know if you've happened to see this particular question in the FAQ, but in case you haven't:

Q. How do I link against system libraries like SDL, boost, etc.?

A. System libraries that are included with emscripten - libc, libc++ (C++ STL) and SDL - are automatically included when you compile (and just the necessary parts of them). You don't even need -lSDL, unlike other compilers (but -lSDL won't hurt either).

Other libraries not included with emscripten, like boost, you would need to compile yourself and link with your program, just as if they were a module in your project. For example, see how BananaBread links in libz. (Note that in the specific case of boost, if you only need the boost headers, you don't need to compile anything.)

Another option for libraries not included is to implement them as a JS library, like emscripten does for libc (minus malloc) and SDL (but not libc++ or malloc). See --js-library in emcc.
