[mrtg] MRTG and SNMPv3

Need some help.  Configuring MRTG for the first time.  Have MRTG (v2.17.4) installed on a Windows 2012 Server with ActivePerl (v5.20.2) and Net-SNMP (v5.5.0).  I used cfgmaker for a base config file and added all my routers.  I am able to capture data from all but the ones that require SNMPv3.

I am running the following command:
E:\mrtg-2.17.4\bin>perl cfgmaker --global "WorkDir: e:\mrtg" --output mrtg.cfg --enablesnmpv3 --username=AdminUser --authpassword=authpassword --authproto=sha --privpassword=privpassword --privprotocol=aes --snmp-options=:::::3 --contextengineid=0 AdminUser at xxx.xxx.xxx.xxx

I get the following error:
WARNING: SNMP V3 libraries not found, SNMP V3 disabled. Falling back to V2c. reverting to snmpV2c for router AdminUser at xxx.xxx.xxx.xxx:::::3<mailto:AdminUser at xxx.xxx.xxx.xxxd:::::3>

I tested this on a Linux server (RHEL7) as well and get the same error.
