Hi,

xqilla sound like a dead project from source forge. It do not use
cmake and for Windows it only compatible with older MSVC version.

Sound like a bad idea.

Yes, Rajce webservice plugin is the only code using QtXmlPatterns. If
i remove the dependency in cmake rules, compilation crying ike that :

So only 2 classes are used from QtXmlPatterns. The question is : why
this classes are used to talk with webservice ? Perhaps there is a
more simplified solution to drop this dependency ?
