        driver_osvr.dylib was installed to:
          #{opt_prefix}/lib/openvr/osvr/bin/osx32/driver_osvr.dylib

        You will want to symlink this driver to the SteamVR drivers location:
          mkdir -p "$HOME/Library/Application Support/Steam/steamapps/common/SteamVR/drivers/osvr/bin/osx32"
          ln -s "#{opt_prefix}/lib/openvr/osvr/bin/osx32/driver_osvr.dylib" "$HOME/Library/Application Support/Steam/SteamApps/common/SteamVR/drivers/osvr/bin/osx32"
        You may additionally want to modify steamvr.vrsettings to force-enable the osvr driver.
