背景

在windows上开发C++的应用经常使用到一些开源C++的库。下载源码编译安装，通常比较繁琐，效率低。希望找到一款类似linux系统的包管理工具，能方便快捷的下载安装所需的C++包。

介绍

vcpkg是一个开源的C++库包管理工具，由Microsoft开发和维护。它旨在简化C++开发人员在Windows、Linux和macOS等操作系统上使用第三方库的过程。通过vcpkg，您可以轻松地安装和管理各种C++库，而无需手动下载和配置。vcpkg提供了一个庞大的库目录，包括常用的开源库，如Boost、OpenCV、OpenGL以及各种C++工具库。您可以使用vcpkg进行库的安装、卸载和更新，并与您的C++项目无缝集成。它使得在C++开发中使用第三方库变得更加方便、快捷和可靠。

安装vcpkg

前提：

1. 确保网络畅通。

下载

Step1：以管理员权限打开powershell

Step2：创建一个vcpkg工作目录，并进入。

PS C:\> cd D:/
PS D:\>

Step3：下载vcpkg

PS D:\> git clone https://github.com/Microsoft/vcpkg.git

安装

Step1：进入vcpkg目录

PS D:\> cd vcpkg
PS D:\vcpkg>

Step2：执行批处理文件进行安装

PS D:\vcpkg> .\bootstrap-vcpkg.bat

Step3：更新

PS D:\vcpkg> ./vcpkg update
Using local portfile versions. To update the local portfiles, use `git pull`.
No packages need updating.

使用vcpkg

以使用vcpkg安装libssh2开源库为例。

1. vcpkg会自动下载安装libssh2编译所需的相关工具；
2. vcpkg自动下载编译libssh2开源库；

PS D:\vcpkg> ./vcpkg install libssh2
warning: In the September 2023 release, the default triplet for vcpkg libraries changed from x86-windows to the detected host triplet (x64-windows). For the old behavior, add --triplet x86-windows . To suppress this message, add --triplet x64-windows .
