LNK2019 - Visual Studio 2013 - 尽管定义了所有符号，但仍然出错答案

【问题标题】：LNK2019 - visual studio 2013 - error despite having defined all symbolsLNK2019 - Visual Studio 2013 - 尽管定义了所有符号，但仍然出错
【发布时间】：2014-09-23 23:48:40
【问题描述】：

我在 Visual Studio 2013 中有一个 Win32 控制台应用程序项目。我已将该项目设置为使用 OpenCV 2.4.9。我也在使用 PGRFlyCapture SDK (http://ww2.ptgrey.com/sdk/flycap)，所以我已经为这个 sdk 配置了 include、bin、lib 的路径。

我创建了一个头文件，以及一个用于定义头文件中声明的所有函数原型的 .cpp 文件。尽管如此，我还是收到了 LNK2019 unresolved external symbol 错误。

我需要帮助摆脱这些 LNK2019 错误。
想要一个指向 PGRFlyCapture SDK 的链接，因为我没有找到它，可能是我在 Visual Studio 中错误地使用项目配置了 SDK。

发布错误列表以供参考。

【问题讨论】：

与Vfw32.lib 的链接 - 这应该可以处理大部分问题。无法帮助FlyCapture2::CameraBase 一个。
我可以在这方面获得更多帮助吗？ Vfw32.lib 在哪里找到？
它带有 Windows SDK，它应该是 Visual Studio 安装的一部分。只需在 Project > Properties > Linker > Input > Additional Dependencies 下提及它。
谢谢！我做了一点挖掘，发现我的系统上没有安装 WindowsSDK。安装它并将 Vfw32.lib 链接到我的项目。除FlyCapture2::CameraBase 外的所有错误均已解决。
@IgorTandetnik，如果您将其作为答案发布，我会接受您的解决方案作为答案。
