我试图用MSVC 2019编译器构建MYSQL驱动程序，但没有成功。我已经检查了所有不同的指令，包括Qt Docs，但都是徒劳的。我以前为MinGW构建过驱动程序，没有遇到麻烦，而且我机器上所有用MinGW作为编译器的项目都连接到MYSQL数据库。现在这个新项目要求我使用用MSVC编译的DLL，特别是要求我使用MSVC 32位。以下是控制台的输出

Qt is now configured for building. Just run 'nmake'.
Once everything is built, you must run 'nmake install'.
Qt will be installed into 'C:\Qt\5.15.2\msvc2019'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

我还在配置文件中发现了一些错误：
项目错误：已加载msvc-version.conf，但未设置QMAKE_MSC_VER。
