【Qt】 Qt 5.15 在线安装

一、Qt 发布公告（2020年5月28日）：

http://download.qt.io/official_releases/qt/5.15/5.15.0/OFFLINE_REAMDE.txt

Due to The Qt Company offering changes, open source offline installers are not available any more since Qt 5.15. Read more about offering changes in the https://www.qt.io/blog/qt-offering-changes-2020 blog.

If you need offline installers, please consider our new Qt for Small Business offering: https://www.qt.io/blog/available-now-qt-for-small-businesses。

大意是：从 Qt 5.15 开始，开源版本，无论是不是 LTS，不再提供编译后的独立安装包，只能在线安装。

如果确实需要离线安装包，则要购买 Qt for Small Business 产品。
