As alternative you can use cmake build system.

Usage

From C++

PhoneFetcher::PhoneFetcher(QObject *parent) :
    Vreen::Client(parent)
{
    auto auth = new Vreen::OAuthConnection(3220807, this);
    auth->setConnectionOption(Vreen::Connection::ShowAuthDialog, true);
    auth->setConnectionOption(Vreen::Connection::KeepAuthData, true);
    setConnection(auth);

    connect(this, &PhoneFetcher::onlineStateChanged, this, &PhoneFetcher::onOnlineChanged);
    connect(roster(), &Vreen::Roster::syncFinished, this, &PhoneFetcher::onSynced);
}

void PhoneFetcher::fetch()
{
    connectToHost();
}

void PhoneFetcher::onOnlineChanged(bool online)
{
    if (online) {
        auto fields = {
            QStringLiteral("first_name"),
            QStringLiteral("last_name"),
            QStringLiteral("contacts")
        };
        roster()->sync(fields);
    }
}

void PhoneFetcher::onSynced(bool success)
{
    if (success) {
        qDebug() << tr("-- %1 contacts recieved").arg(roster()->buddies().count());
        for (const auto &buddy : roster()->buddies()) {
            qDebug() << tr("name: %1, home: %2, mobile: %3").arg(buddy->name())
                        .arg(buddy->homePhone().isEmpty() ? tr("unknown") : buddy->homePhone())
                        .arg(buddy->mobilePhone().isEmpty() ? tr("unknown") : buddy->mobilePhone());
        }
    }
    qApp->quit();

TODO

• Use system browser to receive auth token instead webkit page
• Use more modern C++ features for simplify api
• Add cmake support
• Add qmake project file for Android
