$ ./configure
$ make all
# make install

This will install check_rhev3 to /usr/local/nagios/libexec and the PNP template
to /usr/local/pnp4nagios/share/templates.

To change these paths use the following options:
--prefix=<path_to_nagios_plugins>
--with-pnp-dir=<path_to_pnp_share_folder>

If you don't use PNP you can disable installing the PNP template with:
--disable-pnp-template

To change the user and group ownership of these files use:
--with-nagios-user=<user>
--with-nagios-group=<group>
