MinGW-W64编译MatLab包装DLL遇WinMain未定义及mt命令缺失问题

我尝试将MatLab脚本生成DLL，并制作适配LabView调用的包装DLL，过程中遇到两个编译错误：

• MatLab脚本生成DLL的过程顺利，得到了.dll、.h、.lib、.def等文件；
• 编写包装DLL代码后，使用以下mbuild命令编译：

mbuild -v A0007121_3LIV_W.c A0007121_3LIV.lib LINKFLAGS="$LINKFLAGS /DLL /DEF:A0007121_3LIV_W.def" LDEXT=".dll" CMDLINE250="mt -outputresource:$EXE';'2 -manifest $MANIFEST"

编译时MinGW-W64报错：undefined reference to WinMain；

• 在包装C代码中添加空main函数后，WinMain错误解决，但出现新错误：'mt' is not recognized as an internal or external command, operable program or batch file.

使用环境：MatLab 2019b、MinGW-W64 6.3.0
