Windows has one nice feature in PATH/CPATH handling. You can use
relative paths from the executable location using the exclamation mark
"!". Eg. LUA_CPATH="!/../lib/lua/?.dll". This is especially helpful
for self contained installations, standalone Lua applications etc.
LuaDist[1] extends this functionality to other OSes so it does not
need to install into the system and can be moved around as needed.
Additionally you can set your own defaults in the CMake based build we
provide[2].
