Ncnn: Could NOT find Protobuf (missing: Protobuf_INCLUDE_DIR)

cmake的时候显示如下：

请问是什么问题？？

apt-get install libprotobuf-dev protobuf-compiler

apt-get install libprotobuf-dev protobuf-compiler

But if I'm not root and I have successfully installed protobuf by hand. How can I solve this problem?

[zeakey]

I installed protobuf compiler through conda install.

In my case, adding -DProtobuf_INCLUDE_DIR=/data/home/kaiserzhao/anaconda3/envs/py36/include/google/protobuf
to the cmake command in build.sh solved the problem.
