UIPEthernet.h No such file or directory

I want to develop mqtt client with Arduino uno and ENC28J60. Goal is receiving messages from broker via mqtt to control LED connected with Arduino.

I am following the instruction given in this site https://www.instructables.com/A-Simple-MQTT-PubSub-Node-With-Arduino-UNO-and-ENC/?amp_page=true

i uploaded the sketch as it is but i am getting error

UIPEthernet.h No such file or directory

I need to import this library. To use this library I open the library manager in arduino ide but i don't find there

I also look for the board manager but I can't find it.

my first try, how to fix this error please help me

you have to install the library.
but please use the EthernetENC library for a new project

Please provide the link to download library ?

of course I will use new but I just want to give it try given in sketch

the Library manager in Arduino IDE
