In combination with the +interface version identifiers from /include/openvr.h which are baked +into applications at the time they are built, the OpenVR API client +binding library captures and conveys to the SteamVR runtime the version +of the OpenVR API interface behavior that the application expects. + +Applications carry with them a private/local copy of the client binding +library when they ship, and they should install it locally to their +application. Applications should not install the client binding library +globally or attempt to link to a globally installed client binding library. +Doing so negates at least part of the ability for the client binding library +to accurately reflect the version of the OpenVR API that the application +was built against, and so hinders compatibility support in the face of +API changes. + +Most applications should simply link to and redistribute with their application +the pre-built client binding library found in the /bin directory of this +repository.
