Missing Library Capacitive Sensor Library ?

If if I read my error message correctly, I am missing CapatitiveSensor library but this is supposed to be part of the Arduino Starter Kid? Do I need to got get this from somewhere else or how to I locate it on my own system?

Error Message

Arduino: 1.6.6 (Windows 7), Board: “Arduino/Genuino Uno”

#include <CapacitiveSensor.h>
CapacitiveSensor capSensor = CapacitiveSensor(4,2);

int threshold = 1000;
const int ledPin = 12;

void setup(){
  Serial.begin(9600);
  pinMode(lidPin, OUTPUT);
}

void loop(){
  long sensorValue=capSensor.capacitiveSensor(30);
  Serial.println(sensorValue);
  if(sensorValue > threshold){
    digitalWrite(ledPin,HIGH);
  }
  else{
    digitalWrite(ledPin,LOW);
  }
  delay (10);
}

I don't see it in my pre-installed libraries.

Google says look here.
