Yeah I've looked for it but it doesn't exist (at least free). I've asked the multpl.com guy if he has access to the data to put on his site but he doesn't. Only place I've found is the idea farm, which isn't expensive at all for what you get.
But honestly though, you can just buy the GVAL etf if you are wanting to use CAPE as a global strategy. Or, you can just look at the holdings of GVAL to see what countries are the cheapest if you want to use that as a basis for an individual stock strategy.
