The installation of fwknop is handled by the perl script "install.pl" that
is bundled with the fwknop sources.  Just run:

./install.pl

This will result in a functioning fwknop installation on your Linux system.
If you run the installer as a non-root user, fwknop will be installed in your
home directory (specifically in ~/bin and a few perl modules in ~/lib).  In
this case fwknop can only be used as an authentication client against an
fwknop server on a different system.
