Which pentaho mondrian library to include in a Java application to have mapping MDX to SQL

I want to implement an application that provides support for MDX queries. For this purpose I would like to use one of libraries from pentaho mondrian (an open source OLTP server with the MDX interface) that transforms MDX queries into SQL of underlining database (based on a xml description), unfortunately I can not find any information which libraries I need to include -- and how to use them -- in my project to have MDX to SQL mapping working.

Does anybody have some experience in reusing mondrian components in her/his application?
