include error by using an external project

[mmueller]

Hello together,

currently I'm trying to include the lwm2m-protocol to the esp32-wroom.
So I'm trying among others to include an external project / library in the CMakeLists.txt of my esp32-project.
But cmake can`t find the includes imy "main.c".
I get the error messages `fatal error: lwm2m/connect.h: No such file or directory`;
Or `fatal error: ../../network_common.h: No such file or directory`.
If I get the first error message, then cmake can't find the include from my "main.c".
If I get the second error message, then cmake can't find the include from lwm2m/connect.h.

The external project that I am currently trying to include is wakaamaNode.
Here you can see the link to the external project: https://github.com/smartheim/wakaamaNode.git

I'm working on Ubuntu with with the VSCode-IDE. But the build process i do with idf.py v4.4.6 in the terminal.

Does anyone has an idea how I could include the src.cmake file or the src-directory so that cmake finds the includes?
I would be so gratefull if someone could help me. I currently do not know what I am doing wrong.

In the following I have tried to give an insight into my current project.
