Our Matter samples does not use this cmake file, so I do not think it is generally needed for Matter. You see they enable CONFIG_CHIP in prj.conf.

If you still want to set this MATTER_SDK_DIR we can try to make that work?
Just one thing first: I cannot find the CMakeLists.txt file you are referring to: https://github.com/nrfconnect/sdk-connectedhomeip/tree/master/config/nrfconnect/app.

I want to create a project in NCS2.8.0, while my cmake file as blow:

cmake_minimum_required(VERSION 3.13.1)

# Set Zephyr project
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(my_matter_project)

# Set Matter SDK path
set(MATTER_SDK_DIR /path/to/matter)

# Include Matter CMake file
include(${MATTER_SDK_DIR}/config/nrfconnect/app/CMakeLists.txt)

# Add source file
target_sources(app PRIVATE src/main.c)

But when I build this demo, it popup "undefined CONFIG_CHIP", so I think I have not add matter code to my project.

Could you give me some help? thx

Chuan

That is an unusual question. Maybe it helps for me to know the context. What are you trying to do that makes you need this path?
