### **一、下载VS2019并安装** ###

1、下载地址：[https://visualstudio.microsoft.com/zh-hans/vs/][https_visualstudio.microsoft.com_zh-hans_vs]

2、下载后安装工作负载（安装以下三个即可）

3、如果发现忘记下载某一个工作负载，可以再安装完成之后在重新安装（VS导航栏的工具->获取工具和功能）

### 二、下载并安装cmake-3.16.5 ###

1、下载地址：[https://pan.baidu.com/s/19q6OcG-7KfNScNr4-dKj-A ][https_pan.baidu.com_s_19q6OcG-7KfNScNr4-dKj-A] 提取码：nxv1

2、下载后解压

3、添加环境变量（将解压后cmake-3.16.5-win64-x64文件夹点开进入bin将该路径添加至环境变量，笔者这边的路径为：D:\\software\\cmake-3.16.5-win64-x64\\bin）--如下图

### 三、下载并安装protobuf-3.4.0 ###

1、下载地址：[https://pan.baidu.com/s/1fRV1OpJsUXscUNlC4uvUMA][https_pan.baidu.com_s_1fRV1OpJsUXscUNlC4uvUMA]  提取码：bt4q

2、下载后解压

3、打开VS2019的X64命令行（注意不是cmd）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM2ODkwMzcw_size_16_color_FFFFFF_t_70 2][]

4、在VS2019的X64命令行下执行以下命令

注：<protobuf-root-dir> 为你刚刚解压的protobuf-3.4.0文件夹的根目录

> cd <protobuf-root-dir>
    > mkdir build-vs2019
    > cd build-vs2019
    > 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

5、成功后会产生build-vs2019文件夹以及该文件夹下的若干文件夹及文件

### 四、构建ncnn的library ###

1、ncnn下载地址：[https://github.com/Tencent/ncnn][https_github.com_Tencent_ncnn]  （官网）

2、git clone该项目，或者直接下载压缩包

3、打开VS2019的X64命令行（进入到ncnn根目录下）执行以下语句

注意：cmake -G...这条命令有三个<protobuf-root-dir>需要换成之前安装protobuf-3.4.0的根目录

> cd <ncnn-root-dir>
    > mkdir -p build-vs2019
    > cd build-vs2019
    > cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=%cd%/install -DProtobuf_INCLUDE_DIR=<protobuf-root-dir>/build-vs2019/install/include -DProtobuf_LIBRARIES=<protobuf-root-dir>/build-vs2019/install/lib/libprotobuf.lib -DProtobuf_PROTOC_EXECUTABLE=<protobuf-root-dir>/build-vs2019/install/bin/protoc.exe -DNCNN_VULKAN=OFF ..
    > nmake
    > nmake install

4、成功后会产生build-vs2019文件夹以及该文件夹下的若干文件夹及文件

### 五、下载并安装opencv ###

1、下载地址：[https://github.com/opencv/opencv/releases/tag/3.4.2][https_github.com_opencv_opencv_releases_tag_3.4.2]

下载.exe文件(如下图)

2、下载后解压

3、配置环境变量（跟cmake步骤一样，最后将“压缩包的解压路径\\opencv\\build\\x64\\vc15\\bin”添加进Path即可）
