-# Windows MQTT库安装指南
-
-## 方法1: 使用vcpkg (推荐)
-
-### 1. 安装vcpkg
-```cmd
-git clone https://github.com/Microsoft/vcpkg.git
-cd vcpkg
-.\bootstrap-vcpkg.bat
-```
-
-### 2. 安装MQTT库
-```cmd
-.\vcpkg install paho-mqtt:x64-windows
-.\vcpkg install paho-mqttpp3:x64-windows
-.\vcpkg install nlohmann-json:x64-windows
-```
-
-### 3. 集成到CMake
-```cmd
-.\vcpkg integrate install
-```
-
-### 4. 修改CMake命令
-在构建时添加vcpkg工具链：
-```cmd
-mkdir build
-cd build
-cmake .. -DCMAKE_TOOLCHAIN_FILE=[vcpkg根目录]/scripts/buildsystems/vcpkg.cmake
-cmake --build .
-```
-
-## 方法2: 手动编译
-
-### 1. 编译Paho MQTT C库
-```cmd
-git clone https://github.com/eclipse/paho.mqtt.c.git
-cd paho.mqtt.c
-mkdir build
-cd build
-cmake .. -DPAHO_BUILD_STATIC=TRUE -DPAHO_BUILD_SHARED=FALSE
-cmake --build . --config Release
-cmake --install . --prefix C:/mqtt/c
-```
-
-### 2. 编译Paho MQTT C++库
-```cmd
-git clone https://github.com/eclipse/paho.mqtt.cpp.git
-cd paho.mqtt.cpp
-mkdir build
-cd build
-cmake .. -DPAHO_MQTT_C_PATH=C:/mqtt/c -DPAHO_BUILD_STATIC=TRUE
-cmake --build . --config Release
-cmake --install . --prefix C:/mqtt/cpp
-```
-
-### 3. 修改CMakeLists.txt
-添加库路径：
-```cmake
-set(CMAKE_PREFIX_PATH "C:/mqtt/cpp;C:/mqtt/c")
-find_package(PahoMqttCpp REQUIRED)
-```
-
-## 验证安装
-
-运行以下命令验证：
-```cmd
-cd build
-cmake ..
-```
-
-如果没有错误，说明MQTT库已正确配置。
-
-## 使用示例
-
-在您的代码中导入MQTT：
-```cpp
-#include <mqtt/async_client.h>
-#include "mqtt.hpp"
-
-// 创建MQTT客户端
-auto mqttClient = std::make_unique<custom::MqttClient>("localhost", 1883, "test_client");
-mqttClient->connect();
-mqttClient->subscribe("test/topic");
-```
