Building Coap Client project

Question

Hi, I have just started evaluating nRF52840 using the dongle and Development Kit. I have successfully tested the Openthread network using CLI project. Now I want to try out Soap client and server projects. But when I try to build Soap client, I get 
 d:\Projects
rf\coap_client\src\coap_client_utils.c:8:10: fatal error: coap_server_client_interface.h: No such file or directory 8 | #include <coap_server_client_interface.h> | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. 
 
 I am using SDK 2.0.0. 
 
 What is going wrong here? 
 
 Cheers,

I think I can answer for this myself, in case someone else comes this way. 
 Initially I looked at how the include file paths are specified in the nRF Connect SDK toolchain. I found this is managed through Cmake and specified in target_include_directories (...) 
 So when I looked at the Cmake.txt in the Coap client, I saw 
 target_include_directories (app PUBLIC ../coap_server/interface) 
 This gives the answer that we need Coap server in the same folder level as Coap client. 
 So I created Coap Server project in the same location as my Coap client project and the problem was solved.
