Manifest使用示例3 - 安装并使用本地私有库

使用示例

 本示例包括两部分，第一，构建本地的私有库，第二，使用本地私有库

一、构建本地私有库

构建本地私有库的相关文件， 示例为testport。文件结构：
E:/
|--Manifest/
|----my-ports/
|------testport/
|--------vcpkg.json
|--------portfile.cmake
|--------Source.zip

 vcpkg.json 文件：

{
    "name": "testport",
    "version": "0.0.1",
    "description": "Test manifest mode",
    "dependencies": [
        {
            "name": "vcpkg-cmake",
            "host": true
        },
        {
            "name": "vcpkg-cmake-config",
            "host": true
        }
    ]
}

portfile.cmake 文件：

#设置源码包路径
set(ARCHIVE "${CMAKE_CURRENT_LIST_DIR}/Source.zip")

#解压源码包, SOURCE_PATH的默认值为本场景使用的vcpkg下的buildtrees，本示例中SOURCE_PATH的绝对路径为： E:\Manifest\vcpkg\buildtrees\testport\src
vcpkg_extract_source_archive_ex(
OUT_SOURCE_PATH SOURCE_PATH
ARCHIVE "${ARCHIVE}"
)

#使用CMake配置源文件
vcpkg_cmake_configure(
SOURCE_PATH "${SOURCE_PATH}"
)

#使用CMake安装源文件
vcpkg_cmake_install()

#修复库的config文件的路径
vcpkg_cmake_config_fixup(CONFIG_PATH share/${PORT})

#删除debug目录下的头文件，vcpkg默认直接调用release目录下的头文件
file(REMOVE_RECURSE "${CURRENT_PACKAGES_DIR}/debug/include")

#安装license文件
file(INSTALL "${SOURCE_PATH}/LICENSE" DESTINATION "${CURRENT_PACKAGES_DIR}/share/${PORT}" RENAME copyright)

 

二、使用本地私有库

 在工程目录下创建文件 vcpkg.json, CMakeLists.txt 与 test.cpp 并写入对应代码，同时创建目录BUILD_DIR, 本示例的BUILD_DIR为E:\Manifest\testbuild

文件结构：

E:/
|--Manifest
|----vcpkg.json
|----CMakeLists.txt
|----test.cpp
|----testbuild/

vcpkg.json

{
    "name": "test",
    "version-string": "0.0.1",
    "dependencies": [
        "testport"
    ]
}

CMakeLists.txt

cmake_minimum_required (VERSION 3.8)

project(test)

# Add source to this project's executable.
add_executable (test "test.cpp")

find_package(testport CONFIG REQUIRED)
target_link_libraries(test PRIVATE testport::testport)

test.cpp

#include <iostream>
#include <testport.h>

using namespace std;

int main()
{
    cout << addition(10,5) << endl;
    cout << subtraction(10,5) << endl;
    cout << multiplication(10,5) << endl;
    cout << division(10,5) << endl;

    return 0;
}

 

在CMake工程中使用该库

1. 在testbuild目录中打开cmd窗口，使用CMake命令行编译

"C:\Program Files\CMake\bin\cmake.exe" "E:\Manifest" -G "Visual Studio 17 2022" -A x64 -DCMAKE_CONFIGURATION_TYPES:STRING="Debug" -DCMAKE_TOOLCHAIN_FILE:STRING="E:\Manifest\vcpkg\scripts\buildsystems\vcpkg.cmake" -DVCPKG_OVERLAY_PORTS="E:\Manifest\my-ports"

输出：

2. 构建CMake工程， 生成可执行文件test.exe

"C:\Program Files\CMake\bin\cmake.exe" --build .

输出：

Microsoft (R) Build Engine version 17.3.0-preview-22226-03+b6fc583d4 for .NET Framework
Copyright (C) Microsoft Corporation. All rights reserved.

Checking Build System
Building Custom Rule E:/Manifest/CMakeLists.txt

3. 运行test.exe

输出：

50
2

 

 在MSBuild工程中使用该库

1. 在vcpkg目录中打开powershell并执行命令 .\vcpkg.exe integrate install

2. 用VS打开项目，更改以下项目属性

  • 在项目 — 属性（"Properties"）— 配置属性（"Configuration Properties"）— vcpkg中将 "Use Vcpkg Manifest" 设置为 "Yes" 以启用manifest模式。
  • 在项目 — 属性 — vcpkg中将 User Vcpkg 设为 true，将--overlay-ports="<overlay_abs_prefix>\\my-ports"添加进Additional Options中。


注意：本文档示例testport的安装文件目录为： E:\Manifest\vcpkg_installed\x64-windows。
