where has the adafruit_MCP23017 gone? adafruit_MCP23_ZERO_17

[StefanL38]

the actual version of the adafruit MCP23017-library has th ename
adafruit_MCP23X17.h

between the digits 23 and 7 there is a X

I want to use this library
https://github.com/maxgerhardt/rotary-encoder-over-mcp23017/tree/master

which requires the adafruit_MCP23017.h

between the digits 23 and 7 there is a 0 in words a zero

I tried to modify the Adafruit-MCP23017-Arduino-Library

to use adafruit_MCP23X17.h

but had no success. If gooogle for
github arduino "Adafruit_MCP23017.h"

I get several hits from google.
But if I want to look up the found links, I only get page not found error?
Hu ? what is wrong?

This is the reason why I am asking

The library was refactored a few years back - starting with the 2.0 release:
https://github.com/adafruit/Adafruit-MCP23017-Arduino-Library/releases/tag/2.0.0

That's when the file names where changed. This was a breaking change. So any code using this library (like the one you link) would need to be updated.

The Arduino Library Manager has the option to select a library version. You can try using that to select the 1.3.0 release which has the older file names being used by that rotary encoder library.
