how do I get easyloggingpp to work on macosx?

Question

I am trying to use easyloggingpp (https://github.com/easylogging/easyloggingpp) on MacOSx with clang in clion. Just including the easyloggingc++.h file doesn't work, I get the following errors.

It seems like some symbols are missing, but really, there is only a header file for easyloggingpp, so I am not sure what's missing.

Undefined symbols for architecture x86_64:
  "el::base::utils::s_currentHost", referenced from:
      el::base::LogFormat::updateFormatSpec() in main.cpp.o
  "el::base::utils::s_currentUser", referenced from:

      ...
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

MWE:

#include "easylogging++.h"

int main()
{
     LOG(INFO)<<"Message";
}
