参照readme->PC端调试->编译ncnn 失败

[chenrenxue]

参照readme,在PC端进行编译。步骤如下： 1.下载源码并更新子模块 2.编译protobuf 通过

3. 编译ncnn cd ../3rdparty/src/ncnn mkdir build cd build cmake .. -G "Visual Studio 16 2019" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=%cd%/install -DProtobuf_INCLUDE_DIR=E:\hawk-skys\mtcnn_ncnn\mtcnn_ncnn\3rdparty\include -DProtobuf_LIBRARIES=E:\hawk-skys\mtcnn_ncnn\mtcnn_ncnn\3rdparty\lib\libprotobuf.lib -DProtobuf_PROTOC_EXECUTABLE=E:\hawk-skys\mtcnn_ncnn\mtcnn_ncnn\3rdparty\bin\protoc.exe
