decoupling the include folder from the lib folder is ok :)

typically this problem in the configure script I've found in other
packages are "resolved" putting a list of paths to check; e.g.:
for d in /usr/local/include/lua5.1 /usr/local/include ... ; do
# check if $d is a valid folder
done

Typically, if the includes are in e.g. xxx/include/lua5.1, then the
relative library should be in xxx/lib, i.e. if headers are installed in
a certain prefix, then the library should be in that same prefix.

this is in particular what I do not understand: why creating a
LUA_LIB_DIR and then set it to our local lib folder, which is not going
to ever contain the lua library if USE_SYSTEM_LUA=1?
If we allow for an option called --with-lua-prefix then we must respect
the prefix given by the user using it as base for both the include and
the lib search folders.
Anyway if the current code works, there's no need to further loose time
on it ;)
