It's a bug on master caused by the recent big refactor of
CMakeLists.txt... if you remove libcap-dev, and remove CMakeCache.txt in
your build dir and build again, it should work around it for now.
With some other cmake build options included as well, libcap gets linked
in OK. And if you don't have libcap-dev (the 18.04 CI did not have it
installed), there's no issue either, so it escaped notice until you
pointed it out.
