编译驱动插件参考如下：
Mac Qt 6.2.2 MySQL驱动_U3_Bono的博客-CSDN博客
我遇到的问题：执行$cmake --build . 时出现Failed
[1/1] Linking CXX shared module plugins/sqldrivers/libqsqlmysql.dylib
FAILED: plugins/sqldrivers/libqsqlmysql.dylib

Undefined symbols for architecture x86_64:
可以看到,Mac的m1款其架构师arm64，而不是X86_64,但是在build的时候显示在X86_64架构下，因此我前去寻找办法，经过一系列探索得到:
编辑～/build-sqldrivers/build-ninja文件
vim build-ninja修改build配置，把所有出现-arch x86_64的地方更改成 -arch arm64（记住是所有）
如下：

如果单独更改 Link the shared module plugins/sqldrivers/libqsqlmysql.dylib时的-arch arm64会出现：虽然在/Users/XXX/Qt/6.2.4/macos/plugins/sqldrivers编译出了mysql的插件libqsqlmysql.dylib，但是最后无法正确链接，出现Qt creater无法加载的情况！！！！
