【问题描述】：
我在一个引擎中实现了 assimp 5.0.1，我无法链接它，我想这是因为包含它的方式，但我不知道我做错了什么。
我在 Windows 中，使用 Visual Studio 2019 (C++)，我采取的步骤是使用 cmake 作为文档中的状态构建 assimp，并将文件夹“code/”、“contrib/”和“include/”复制到该项目位于“Assimp”文件夹中。有了这个，我制作了一个 premake 文件来在引擎的项目中构建它（我使用 premake5 作为生成器）。
问题是我收到 5 个链接器错误。我假设我没有在预制中包含一些需要的文件。链接器错误是下一个：
包含包含导致链接器错误的函数的文件会带来更多的链接器问题，我无法通过不断添加或包含文件来解决这些问题，因此我不知道该怎么做。
在预制文件（复制如下）中，例如，如果我注释一些定义，如“ASSIMP_BUILD_NO_IFC_IMPORTER”，它将触发更多链接器错误（在这种情况下为 IFC 函数），这就是为什么我猜有一些错误的包含或某物。有谁知道它可能是错的吗？会不会很有帮助，因为我真的迷路了，我已经用了一周了。
我正在使用的预制文件是下一个：
