Library paths include wrong \

When building for iOS a Cardboard app, the Library paths get all mixed up which makes the building in XCode a step more complex because we need to remind every time that we need to change the \ to / in the library paths.

"Library\Plugins/IOS" something similar to this happens and then needs to be changed to "Library/Plugins/IOS"

I'm using the Cardboard SDK so I'm not sure how that is affecting the build process, but the error I get is a lib not being found.
