You might be able to achieve this by calling 
QDeclarativeEngine::addImportPath(). E.g. if your import statement is 
'import MyPlugin 1.0', you can try to include your qmldir file as 
qrc:/imports/MyPlugin/qmldir', and call 
engine->addImportPath("qrc:/imports") before loading the main file in 
the engine. Obviously the .qml files that make up the plugin should then 
be also available under qrc:/imports/MyPlugin . I haven't tried that 
myself, though.

Anyhow, may I ask why you want to put it in the resources in the first 
place? The idea of a QML plugin is that it contains stuff you want to 
share between apps, and compiling it into the resource system seems to 
somewhat contradict this.
