Hello,
yes you need to have LZO include and lib installed in your system AND you need 
to compile bacula (client, storage and director) in order to get LZO 
compression support.

There is a major compression speed improvement in LZO 2.05 and up on 64bits 
Intel system. Check that you have at least LZO 2.05.

There is no option in configure script like for GZIP compression. The configure 
script will auto-detect the lib. Please check that your compiler have access to 
lzo include files and lzo lib.

At the end of the configure script execution, you get detailed output with all 
options/ settings. Check that lzo support is on before compiling bacula.

Here is a part of the output with LZO option:
   Large file support:       yes
   Bacula conio support:     no -lreadline -ltinfo
   readline support:         yes 
   TCP Wrappers support:     yes -lwrap
   TLS support:              yes
   Encryption support:       yes
   ZLIB support:             yes
   LZO support:              yes
   enable-smartalloc:        yes
   enable-lockmgr:           no
   bat support:              yes
   enable-gnome:             no 
   enable-bwx-console:       no 
   enable-tray-monitor:      no
   client-only:              no
   build-dird:               yes
   build-stored:             yes
   Plugin support:           yes
   ACL support:              yes
   XATTR support:            yes
   Python support:           yes -lpthread -ldl -lutil -lm -lpython2.7 -lutil 
-lrt systemd support:          no 
   Batch insert enabled:     PostgreSQL MySQL SQLite3

Regards.
