QT: positioning location hatası

Merhaba 

Raspberryde ubuntu qt creatordaki harita uygulamasını çalıştırmayı denediğim de "Project ERROR: Unknown module(s) in QT: positioning location" hatası ile karşılaşıyorum. 

Proje içerisindeki 

import QtLocation 5.6 üzerine geldiğim zaman

QML module not found ( QtLocation ) 

Import paths:
/opt/qtrpi/raspi/qt5pi/qml

For qmake projects, use the QML_IMPORT_PATH variable to add import paths
For Qbs projects, declare and set a qmlImportPaths property in your product to add import paths
For qmlproject projects, use the importPaths property to add import paths
For cmake projects, make sure QML_IMPORT_PATH variable is in CMakeCache.txt

import QtPositioning 5.5 üzerine geldiğim zamanda

QML module not found ( QtPositioning ). Import paths:/opt/qtrpi/raspi/qt5pi/qml For qmake projects, 
use the QML_IMPORT_PATH variable to add import paths. For Qbs projects, declare and set
a qmlImportPaths property in your product to add import paths. For qmlproject projects,
use the importPaths property to add import paths. For cmake projects, make sure QML_IMPORT_PATH variable
is in CMakeCache.txt

The QtPositioning global object provides useful functions for working with location-based types in QML

hatası ile karşılaşıyorum. 

Bunları nasıl çözebilirim.

Teşekkürler.
