不用。
Qt的3rdparty中已经包含了sqlite3的代码。
看一下这几个configure选项
-no-sql-<driver> ... Disable SQL <driver> entirely, by default none are
turned on.
-qt-sql-<driver> ... Enable a SQL <driver> in the Qt Library.
-plugin-sql-<driver> Enable SQL <driver> as a plugin to be linked to at run
time.
Available values for <driver>:
mysql
psql
oci
odbc
tds
db2
+ sqlite
sqlite2
ibase
(drivers marked with a '+' have been detected as
available on this system)
-system-sqlite ..... Use sqlite from the operating system.
-no-qt3support ..... Disables the Qt 3 support functionality.
