CMake when FetchContent rabbitmq - c++

Question

I am trying to integrate rabbitmq into one of the modules of my solution in order to switch from mailslots to rabbitmq. The problem is that during the fectcontent, the module "breaks" the links of the other modules. The errors generated are "unresolved external symbols".
