一、将QT6的4个目录回到系统搜索路径中：
二、开始安装：
1.编译代码
D:\Qt\Packages\qtmqtt-6.5.0>D:\Qt\6.5.0\mingw_64\bin\qt-configure-module.bat .
D:\Qt\Packages\qtmqtt-6.5.0>cmake --build .2.安装控件
D:\Qt\Packages\qtmqtt-6.5.0>cmake --install . --verbose3.安装过程如下：
D:\Qt\Packages\qtmqtt-6.5.0>D:\Qt\6.5.0\mingw_64\bin\qt-configure-module.bat .
'D:\Qt\6.5.0\mingw_64\bin\\qt-cmake-private.bat' '.'
