the error i am getting is
undefined reference to `ashAckTimer'
FYI : kept header file in source "abc.c" file

Kindly let me know the reason
using espidf v5.4.1 with zigbee SDK4.4.6
Attached a image of projet where getting error

Kindly let me know the reasons

From what you show I'm pretty sure there are more errors and/or warnings put out by the build process, which are relevant.

As a start, change to in the CMakeLists.txt.

Yes, I already have written that as you suggested
