编译成功！QT/6.7.2/Creator编译Windows64 MySQL驱动
找了很多编译博文，都错误。最后找到了正确编译办法：
https://zhuanlan.zhihu.com/p/567883165
- 直接下载编译好的源码及dll文件
https://download.csdn.net/download/quantum7/89760587
- 安装VS Virsual Studio 2022 Community
D:\Program Files\Microsoft Visual Studio\2022\Community
要有VC++/cmake等。
- 安装MySQL
C:\Program Files\MySQL\MySQL Server 8.0
- 安装QT
D:\Qt
要选中三项：
MSVC_2019 64-bit
MinGW 11.2.0 64 bit
Sources
- 配置路径
根据自己的安装来设置，也可以设置到系统路径中。
