How to include Net-SNMP to QT project

I'm trying to run this project: https://github.com/vanhsati/SNMP-Monitor Downloaded net-SNMP from: https://sourceforge.net/projects/net-snmp/files/latest/download I get a lot of errors when I try to build project. Example code from official net-SNMP wiki also includes only two ".h" files. How can I properly link the library to QT creator?
