Answering my own question:
LUA_COMPAT_MODULE seems to be a compiletime option for Lua, not wxlua.
One that my distribution does not use.
I get the same error when I set all the wxlua options to 5.1, and that
still contains luaL_register, according to documentation
(http://www.lua.org/manual/5.1/manual.html).

My guess is that cmake still uses whatever Lua version it can find on
the system. While I do have Lua 5.1 and 5.2 installed, the default Lua
version of my distribution is now 5.3. So, cmake probably uses that,
despite me specifying something else. I guess that counts as a bug in
the cmake script.

I could build it successfully using the Lua 5.1 that ships with wxLua.
(-DwxLua_LUA_LIBRARY_USE_BUILTIN=1)
I just hope that things will work out with that.

Regards,
Philipp
