包括DLL中的OpenVDB;将错误与Visual Studio 2015联系起来

我正在尝试编译，在Visual Studio 2015中，我正在制作的DLL，它可以用作OpenVDB的某些功能的C兼容包装器，使其在现有的C项目中可用。但是，当我构建时，我会收到以下链接器错误：

OpenVDB及其所有依赖项都在Include文件夹中，其目录已添加到附加目录中，这是我当前链接器选项下其他依赖项的列表：

• blosc.lib
• cppunit.lib
• glew32.lib
• glfw3.lib
• 一半
• iex-2_2.lib
• iexmath-2_2.lib
• ilmimf-2_2.lib

我似乎找不到有关视觉工作室中使用OpenVDB编译的任何信息，这些信息涵盖了这种错误，并且对我可能会忘记的东西感到非常困惑。
