Zabbix Proxy

HOWTO
Building zabbix-proxy on ubuntu
On Ubuntu-22.04 i had:
./configure --enable-agent --enable-proxy --with-sqlite3 --with-openipmi --with-net-snmp --with-gnutls --with-libcurl
requiring:
apt-get install gcc make libsqlite3-dev zlib1g-dev libevent-dev libpcre3-dev libsnmp-dev libopenipmi-dev libgnutls28-dev libcurl4-gnutls-dev
Zabbix proxy was compiled without VMware support
apt install libxml2-dev
and
--with-libxml2
configure: error: LIBXML2 library not found
apt install pkg-config
