Crosswalk seems dead

Could somebody please tell me in more or less practical words how to run XWalkCoreLib or how to link apps that need a webview to it?
The version is 23 and the device an alcatel 4013 D kitkat 4.4.2 ARM, rooted and running APK editor and toolbox.
It’s seen XWalkCoreLib works since the app ‘‘embedding API XWalk’’, from the same developer, browse web pages thanks to such link, but XWalkCoreLib opens not.
There’s no system webview in the device.
