vs2015 ncnn

1、vs2015编译器编译protobuf   （VS2015 x64本机工具命令）

下载源码：https://github.com/google/protobuf/archive/v3.4.0.zip
进入protobuf-3.4.0 文件夹

mkdir build-vs2015
cd build-vs2015
cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=%cd%/install -Dprotobuf_BUILD_TESTS=OFF -Dprotobuf_MSVC_STATIC_RUNTIME=OFF ../cmake
nmake
nmake install

protobuf-3.4.0\build-vs2015\install 目录下，会生成include bin lib文件夹

2、ncnn

下载源码

https://github.com/Tencent/ncnn/releases

cd build-vs2015

cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=%cd%/install   -DProtobuf_INCLUDE_DIR=E:/NCNNWin/protobuf-3.4.0/build-vs2015/install/include
-DProtobuf_LIBRARIES=E:/NCNNWin/protobuf-3.4.0/build-vs2015/install/lib/libprotobuf.lib  -DProtobuf_PROTOC_EXECUTABLE=E:/NCNNWin/protobuf-3.4.0/build-vs2015/install/bin/protoc.exe ..

nmake

nmake install

在ncnn-20180830\build-vs2015\install 文件夹下生成include和lib文件夹
