windows下安装失败

请问我在windows下 使用 MinGW 来构建时
执行 cp make/mingw64.mk config.mk 提示：cp: cannot stat 'make/mingw64.mk': No such file or directory。是什么原因，是前面有缺失的步骤吗？ 请指教，多谢了 。

Start by checking whether make/mingw64.mk exists in the repository and compare the documented MinGW command with the available build files. Reproduce the reported cp failure on Windows/MinGW if possible; done means identifying the missing step or correcting the installation guidance.
