How to specify path to SQLite in PDO driver?

On a Centos6 SQLite 3.6 was installed by default. But I need one more version of SQLite 3.8 for PHP. So I just downloaded 3.8 sources and compile it without make install. Now default version is 3.6 but I can launch 3.8 running it from directory where it was compiled. how can I specify for PDO to use not default version of SQLite, but use custom version compiled in user/local?
