You can execute other bits of Lua code from the C api too... so you
_could_ just include a small constant string in your C program,
containing Lua "init" code that does all the module loading and other
setup you want, and run that code snippet before loading the main
script:
static const char init_lua_code[] = "...some lua code...";
luaL_loadstring (L, init_lua_code);
// optionally push arguments the lua code uses
lua_call (L, 0/*number of args*/, 0);
Alternatively, it's easy to just call the Lua require function:
lua_getglobal (L, "require"); // function
lua_pushstring (L, "mymodulename"); // arg 0
lua_call (L, 1, 1); // call require; returns 1 val
// If it's a 5.1/5.2-style module, it will return the module table, so
// store that in a global variable:
lua_setglobal (L, "mymodulevar"); // maybe same name as above
