java - Android Studio CMake 错误：构建命令失败 fasttext

Question

我正在尝试使用 NDK 在 Android 中使用本机代码（C++）。当我尝试制作项目时，我遇到了构建失败。c++ 代码取自https://github.com/facebookresearch/fastText/tree/master/src。它被添加到以下位置 C:\Users\xxx\AndroidStudioProjects\blah\app\src\main\cpp。

我的 CMake 文件的内容：

cmake_minimum_required(VERSION 2.8.9)
