> 以libssh2为例说明如何在命令行中使用vcpkg

# 准备 #

1、[win10安装cmake][win10_cmake]

3、[vcpkg：win和linux中安装vcpkg][vcpkg_win_linux_vcpkg]

2、安装libssh2

> vcpkg install libssh2:x64-windows

# 代码编写 #

## 准备 ##

1、创建目录`libssh2_test`。 我的完整目录是C:\\Users\\oceanstar\\source\\repos\\libssh2\_test

cmake\_test.h

#pragma once
    
    #include <iostream>

cmake\_test.cpp

#include <libssh2.h>
    #include <libssh2_sftp.h>
    #include <sys/types.h>
    #include <fcntl.h>
    #include <errno.h>
    #include <stdio.h>
    #include <ctype.h>
    
    
    int main(int argc, char* argv[])
    {
        
    
    
        if (!libssh2_version(LIBSSH2_VERSION_NUM)) {
        
            fprintf(stderr, "Runtime libssh2 version too old!");
            exit(1);
        }
        printf("libssh2 version: %s", libssh2_version(0));
        return 0;
    }

## 方法一 ##

CMakeLists.txt：

cmake_minimum_required (VERSION 3.8)
    
    project ("cmake_test")
    
    
    cmake_minimum_required (VERSION 3.8)
    
     
    # 将源代码添加到此项目的可执行文件。
    add_executable (cmake_test "cmake_test.cpp" "cmake_test.h")
    
    # TODO: 如有需要，请添加测试并安装目标。
    find_package(Libssh2 CONFIG REQUIRED)
    target_link_libraries(cmake_test PRIVATE Libssh2::libssh2)

打开PowerShell（注意一定要是PowerShell，Cmd没有用），进入C:/Users/oceanstar/source/repos/libssh2\_test/build，执行如下命令：`cmake .. -DCMAKE_TOOLCHAIN_FILE=C:/Users/oceanstar/vcpkg/win/vcpkg/scripts/buildsystems/vcpkg.cmake`

成功。

## 方法二 ##

CMakeLists.txt：（这里需要注意的是，设置CMAKE\_TOOLCHAIN\_FILE要在project()命令之前）

cmake_minimum_required (VERSION 3.8)
    
    SET(CMAKE_TOOLCHAIN_FILE "C:/Users/oceanstar/vcpkg/win/vcpkg/scripts/buildsystems/vcpkg.cmake")
    project ("cmake_test")
    
    
    cmake_minimum_required (VERSION 3.8)
    
     
    # 将源代码添加到此项目的可执行文件。
    add_executable (cmake_test "cmake_test.cpp" "cmake_test.h")
    
    # TODO: 如有需要，请添加测试并安装目标。
    find_package(Libssh2 CONFIG REQUIRED)
    target_link_libraries(cmake_test PRIVATE Libssh2::libssh2)

打开PowerShell（注意一定要是PowerShell，Cmd没有用），进入C:/Users/oceanstar/source/repos/libssh2\_test/build，执行如下命令：`cmake ..`
