Qt should report error if trying to send POST request using QNetworkAccessManager to https endpoints without OpenSSL support

Even if SSL is enabled when configuring Qt for compilation in Linux, it is not guaranteed that SSL support is enabled in Qt, if for example libssl-dev package on Ubuntu/Debian is missing while compiling Qt. Now it is impossible to discover this issue when using QNetworkAccessManager. For example:

QNetworkAccessManager *networkManager = new QNetworkAccessManager(this);
QNetworkRequest networkRequest;
networkRequest.setUrl( QUrl("https://api.twitter.com/oauth/authorize") );
networkRequest.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");

...
...
connect(networkManager, SIGNAL(finished(QNetworkReply *)),
this, SLOT(onRequestReplyReceived(QNetworkReply*) ));
QNetworkReply *reply = networkManager->post(networkRequest, QByteArray("Some body"));

signal "finished()" is never emitted and reply->error() gives NoError. Also Wireshark shows that the packets are never submitted through the ethernet controller, so QNetworkAccessManager cannot tell me that everything is fine.
