QT使用 windeployqt.exe打包后打开exe提示缺少dll

在windows10 下的debug模式下打包的 X64  exe

本机可以正常打开，但是放到windows7 X64电脑上就不行了

Remember to call vcvarsall.bat to complete environment setup!

没有报错，本机也可以运行

在网上找到解决办法了 需要把vs相关环境设置下，然后在qt命令行中执行下这个 vcvarsall.bat
call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Auxiliary\Build\vcvarsall.bat" x64
我的是64位的，大家的看情况选择适合自己的
