Hi,
Select any ADC pin, do the required configurations. Connect the LDR and read the value from the ADC register.
LDR is a Light Dependent Resistor, so its value of Resistance change with the light that the LDR receive.
The more light the less resistance.
You must get a network of resistances for example in serial to convert the variation of resistance in a variation of voltage.

As AJISH ALFRED have said before connect it at an Analog Input of the PIC and read the analogic value
