C++ “WinMainCRTStartup”和其他一些函数的多重定义

在我将带有库和编译器的文件夹复制到笔记本电脑并设置项目后，我出现以下错误：

C:\PCL\3rdParty\VTK\bin\vtkEncodeString-6.0.exe: In function `WinMainCRTStartup':
/home/ruben/mingw-w64/src/mingw-w64/mingw-w64-crt/crt/crtexe.c:154: multiple definition of `WinMainCRTStartup'

C:\PCL\3rdParty\VTK\bin\vtkEncodeString-6.0.exe:crtexe.c:(.CRT+0x8): multiple definition of `mingw_pcppinit'

我花了几个小时寻找解决办法，但没有成功

有人能指出我做错了什么吗？谢谢
