2 years ago ncnn 源码下有 tools/darknet 目录， tools/darknet 目录下有 CMakeLists.txt , 因此如果使用了没有修改过的原版 ncnn 源码工程的话， cmake 执行 add_subdirectory(darknet）不应该报错。
注意， ncnn 并不是把 darknet 整个工程包含进来， https://github.com/Tencent/ncnn/tree/master/tools/darknet 这里是提供了模型转换的代码，即：从头写的、和原版 darknet 没有关系。
可考虑检查编译报错时的 ncnn 工程目录， 和github上原版的是否有差别，例如不小心手动删除了 darknet 目录、别人共享来的 ncnn 工程等。

darknet的目录不在ncnn的原始项目代码目录里吗？
下面是tools/CMakeLists.txt相关的代码 add_subdirectory(caffe) add_subdirectory(mxnet) add_subdirectory(onnx) add_subdirectory(darknet)
