How to use pdfsig from poppler-utils

I would like to use pdfsig from poppler-utils in my ubuntu 16.04, at first I installed poppler utils from apt but pdfsig was not part of that package. When I looked man pages for 'pdfinfo' in the SEE ALSO section, according to http://manpages.ubuntu.com/manpages/artful/man1/pdfinfo.1.html it should appear pdfsig(1), but in my ubuntu 16.04 there were just a few ones and pdfsig was missing. I looked for the sources to compile, from https://poppler.freedesktop.org/ I downloaded and compiled poppler-0.65.0.tar.xz. Now when I see the manpages for pdfinfo I can see pdfsig(1) in the SEE ALSO section. But when I try to run pdfsig in command line, nothing happens and a message saying pdfsig: command not found appears. Also if I try to look man pages for pdfsig like man pdfsig or man 1 pdfsig, a message saying No manual entry pdfsig or No manual entry for pdfsig in section 1 appears. Am I missing something? please if someone knows how to use pdfsig I would really appreciate help. Thanks in advance.
