cmake compiled the code perfectly, not sure what to do next

I am working on a raspberry pi trying to get an LCD to work with an
MCP I/O expander.
After cloning and
compiling the software
the files below are left. The logs are here.

With Python I end up with a py file I can edit and play with. not

sure what to do here.
Thank you.

I suggest asking for assistance on the repository you linked. CMake has done its job here; documentation in the specific project would be the next place to look/ask.
