Bug#738617: /usr/lib/x86_64-linux-gnu/qt5/bin/lupdate: lupdate would need qmldevtools to collect translation strings from qml files

[Pauli <suokkos@gmail.com>]

Package: qttools5-dev-tools
Version: 5.2.0-9
Severity: minor
File: /usr/lib/x86_64-linux-gnu/qt5/bin/lupdate

Dear Maintainer,

lupdate has conditional support to collect strings from qml files. To
enable qml support qttools build would need access to qmldevtools module.
If I understand qt module system correctly that would mean build
dependency to qtdeclarative5-private-dev.

The optional dependency is in 
src/linguist/lupdate/lupdate.pro

test.pro:
TARGET = test

QT += quick

lupdate_only {
SOURCES += test.qml
}

TRANSLATIONS = en.ts

OTHER_FILES = test.qml


test.qml:

import QtQuick 2.0

Rectangle {
	width: 400
	height: 400

	Text {
		text: qsTr("Translated text")
	}
}


result:
$ lupdate test.pro 
lupdate warning: Some files have been ignored due to missing qml/javascript support
Updating 'en.ts'...
    Found 0 source text(s) (0 new and 0 already existing)

Thanks,
Pauli
