I usually have a "bootloader" C program that creates a Lua state and
exposes some internals to it and lets it go nuts. A lot of my programs
however are a Lua script that loads a bunch of modules (some of which
are written in C); it's not infeasible that a game engine could be
done that way.

There is no best way, except whichever works best for you.
