try -lgpiod -lpthread -lgpiodcxx
Here is a cmake snippet that I just use by default on gpio stuff.
Your code is fine, just ran it here and it is just using gpiodcxx
Here is the complete cmake
So, at this point you might not have the libraries installed correctly.
Look for this
Here is a trail of bread crumbs if you want to try the cmake:
when you execute the cmake make sure you have .. after it.
