im also facing the same error :(

By not providing "Findncnn.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "ncnn", but CMake did not find one.

请问你解决了吗

这个可以跑 https://github.com/hdu-CXSJ/GarbageClassification

可以试试修改ncnn-android-yolov5-master\app\src\main\jni中的CMakeLists.txt文件 删掉下图文件中的中蓝色部分
