CMake pains - cannot get it to correctly find a C++ Library?

My Initial Question was here

https://stackoverflow.com/questions/55998144/when-i-build-and-compile-my-c-project-it-is-not-finding-the-correct-c-librar 

but it seems to have died

https://github.com/Some-T/MobileSimSetup/tree/master/CLion

My up to date project is here

It seems to be finding the directories ok on my system for the libraries, but its still causing errors upon compilation it is not working.

I can't work out within the scope of CLion or other C++ related (GCC) thing I am doing incorrectly in order to solve why this will not work.

The error output I am getting when trying to compile is here:

How do I fix this all? What is going wrong exactly? It is a bit challenging to pin down exactly what. I think my cmake files are correct?
