我正在使用CMake gui将assimp导入Xcode中的openGL项目中。我正在按照此处的说明进行操作：How to import assimp to my my Xcode project?
但是，我的Assimp.xcodeproj无法生成。
这是Xcode中的错误消息：
Invalid operands to binary expression ('float (*)(const char *, const char *)' and 'nullptr_t')
（D3MFImporter.cpp行230）
这是我在CMake gui中得到的警告：

我不确定为什么会有语法错误，因为我确信很多人使用assimp都没有问题。任何帮助将不胜感激！
