我已经安装了 DirectX，但它也不起作用。我找不到解决方案。 assimp 版本是 3.3.1。我也已经尝试用 Visual Studio 2017 编译它了。

【解决方案1】：

这个问题是由我们的旧模型查看器引起的。目前它希望在您的机器上安装旧的 DirectX9 SDK。要解决此问题，只需查找 DX-9.0a SDK（只需 google 即可）并将其安装在默认位置。

您也可以在禁用工具支持的情况下运行 cmake 脚本。那么DX-SDK就不需要了，问题就不会再出现了：

assimp_root_folder>cmake CMakeLists.txt -DASSIMP_BUILD_ASSIMP_TOOLS=OFF
