我使用QtNetwork 去访问https的网站时，就提示下面这些错误
QSslSocket: cannot call unresolved function SSLv23_client_method
QSslSocket: cannot call unresolved function SSL_CTX_new
QSslSocket: cannot call unresolved function SSL_library_init
QSslSocket: cannot call unresolved function ERR_get_error
QSslSocket: cannot call unresolved function ERR_get_error
但是我已经把libeay32.dll、ssleay32.dll放到system32文件夹里面了还是这样，以前我用Qt4.8.2都是可以的，现在怎么不可以了，而且现在装回4.8.2还是不行，有人知道这是为什么吗？
