Unfortunately you ultimately need the relationship which you have for
cLuaState->lua_State to work back the other way for lua_State->cLuaState

Your choices really are:
     1. Alter lua_State to include a cLuaState*
     2. Create a static mapping somewhere from lua_State* to cLuaState*

unfortunately that's it. Now either you map it inside the cLuaState object,
or you'll have to map it elsewhere.

The only other option is to make all the functions which need the cLuaState
pointer use a userdata to pass that in as a closure value.

The last option is perhaps what you'll end up doing, but isn't the most
elegant due to a need to remember to do that for each function you register
