背景：
当前的QT环境为5.14，qt6对3D等特效支持更好，于是打算升级到QT6。 第一次安装使用在线安装方式，无奈启动之后，界面中文显示乱码，调了半天没搞定。于是决定安装qt-creator12搭配使用qt6。
步骤
第一步： 下载 qt-unified-linux-x64-online.run
执行安装 ./qt-unified-linux-x64-online.run
之后到安装界面的时候，将QT creator 的勾选去掉，仅勾选Qt，一路“下一步”，等待安装完成。
第二步：
当前只是安装好了QT，打开QT creator，使用QT6的工程编译，依然会报错。需要配置编译套件kits

set(CMAKE_PREFIX_PATH "/home/topeet/qt-creator/qt6_install/6.8.0/gcc_64")编译通过。
编译套件的详细配置如下：
