在 Windows 10 上构建 Vivek 的虚拟相机时出现链接器错误？

问题描述

我正在尝试在 Windows 10 上构建 Vivek's Virtual Camera。
为此，我需要 Win7Samples/multimedia/directshow/baseclasses

我已下载 baseclasses 并使用 Visual Studio 2019 构建它。
现在我准备构建虚拟相机过滤器。我遵循了一些必要的步骤

git clone https://github.com/roman380/tmhare.mvps.org-vcam
cd tmhare.mvps.org-vcam\Filters
然后我尝试在 Visual Studio 2019 中打开 Filters.dsp，它要求我执行 one-way upgrade
在C:\Users\alokm\tmp\Windows-classic-samples\Samples\Win7Samples\multimedia\directshow\baseclasses
中添加了Additional Include Directories
将 C:\Users\alokm\tmp\Windows-classic-samples\Samples\Win7Samples\multimedia\directshow\baseclasses\Debug 添加到 Addition Library Directories
完成所有这些步骤后，我尝试通过点击 Build >> Build Solution
但是我收到了很多链接器错误。
