-DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DMYSQL_UNIX_ADDR=/u04/my3306/run/mysql.sock \
-DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci -DCMAKE_C_FLAGS_RELWITHDEBINFO="-O2 -g" \
-DCMAKE_CXX_FLAGS_RELWITHDEBINFO="-O2 -g" \

And end of CMakeError.log as follows, and it seems like I had miss event.h file.

Can anyone knows how to fix this problem ?
