在Windows10中构建Win32版本Ffmpeg时显示错误，如何解决？

问题描述

我构建了一个Win32版本的ffmpeg，以便按照https://trac.ffmpeg.org/wiki/CompilationGuide/WinRT文档的要求在Windows10中获取.dll和.lib文件，我执行了命令

    ../../../configure \
--toolchain=msvc \
--disable-programs \
--disable-d3d11va \
--disable-dxva2 \
--arch=x86 \
--enable-shared \
--enable-cross-compile \
--target-os=win32 \
--extra-cflags="-MD -DWINAPI_FAMILY=WINAPI_FAMILY_APP -D_WIN32_WINNT=0x0A00" \
--extra-ldflags="-APPCONTAINER WindowsApp.lib" \
--prefix=../../../Build/Windows10/x86

一切正常，之后，我执行命令：

make

显示错误：
