These libraries are for using the ESP8266 itself as an Arduino-device, not for connecting an ESP8266 to another Arduino. You can't run ESP8266-specific code on an UNO. If you have an ESP8266 connected to your UNO and you want to use the UNO as the main-device and the ESP8266 just for WiFi then these libraries are not what you need.
