Right now, just do make. This will compile jit.cpp, a series of functions
that can be accessed from Lisp and act as Hylas' backend, then compile the basic console frontend.
make system will symlink the folder where Hylas resides to your quicklisp/local-projects folder, so Hylas can be Quickloaded as a library.
make gui builds the (Experimental, not production ready) Syntagma IDE.
