Well, it's optional.

If you want XSLT support, you need libxslt, which in turn needs libxml2.

If you don't want XSLT support, then that's fine and we'll fall back to using
Qt's built-in XML parser.

But as it stands today, Qt's support for XSLT is not up to the task and there 
haven't been any efforts in the recent years to significantly close the gap 
between libxslt and QtXmlPatterns in terms of completeless of XSLT support.
