问题
I am pretty new to Linux and I am having problems integrating an external software into my program. When I am following the instructions on integrating a couple of lines that includes Jansson (Add G4Sipm to your CMakeLists.txt in this document enter link description here) I get errors which I suspect is the problem of integration itself since it does separately build on its own. The errors I get are after command build -j2. Here is a part of the terminal output:

I tried adding #include <jansson_config.h> instead of #include "jansson_config.h" however errors still persisted. I tried contacting the project lead however it seems they have all moved on from the project. Any help and suggestions would be greatly appreciated, thank you!
Edit 1: for clarification, I am using the latest version of Jansson
