Centreon Engine directory /usr/sbin because we used in cmake -DWITH_PREFIX_BIN=/usr/sbin
Centreon Engine Stats binary /usr/sbin/centenginestats
Centreon Engine var lib directory /var/lib64/centreon-engine because we used in cmake -DWITH_RW_DIR=/var/lib64/centreon-engine/rw
Centreon Engine Connector path /usr/lib64/centreon-connector because we used in cmake -DWITH_PREFIX_BINARY=/usr/lib64/centreon-connector
