我正在尝试使用包含webkit的Visual Studio 2013 SP5将Qt 4.8.6构建为x64静态库，但是在运行nmake几分钟后我收到此错误：

当我没有显式配置qt来构建webkit时，这个问题不存在，即使它是默认选项，也不会以其他方式构建。 这也是我使用的配置：
configure -opensource -release -static -webkit -platform win32-msvc2013
我理解我的问题可能类似于this one，但由于Qt 4.8.6支持Visual Studio 2013，我认为这个问题有不同的原因。此外，我已经尝试移动所有必需的包，甚至重新安装VS，以确保我使用的PATH不包含任何空格或不“太长”。我搜索了很多指南和帖子但似乎没有任何帮助我。 有什么东西可能会丢失吗？
