== 实际案例：使用Conan管理Boost库 ==
以下是一个完整的示例，展示如何使用Conan和CMake集成Boost库。

=== 项目结构 ===
<pre>
my_project/
├── CMakeLists.txt
├── conanfile.txt
└── src/
    └── main.cpp
</pre>

=== conanfile.txt ===
<syntaxhighlight lang="ini">
[requires]
boost/1.81.0

[generators]
cmake
</syntaxhighlight>

=== CMakeLists.txt ===
<syntaxhighlight lang="cmake">
cmake_minimum_required(VERSION 3.15)
project(MyProject)

# 包含Conan生成的配置文件
include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
conan_basic_setup()

add_executable(my_app src/main.cpp)
target_link_libraries(my_app ${CONAN_LIBS})
</syntaxhighlight>

=== src/main.cpp ===
<syntaxhighlight lang="cpp">
#include <boost/algorithm/string.hpp>
#include <iostream>
#include <string>

int main() {
    std::string text = "Hello, Boost!";
    std::cout << "Original: " << text << std::endl;
    boost::to_upper(text);
    std::cout << "Uppercase: " << text << std::endl;
    return 0;
}
</syntaxhighlight>

=== 构建与运行 ===
<syntaxhighlight lang="bash">
mkdir build && cd build
conan install .. --build=missing
cmake ..
cmake --build .
./my_app
</syntaxhighlight>

=== 输出 ===
<pre>
Original: Hello, Boost!
Uppercase: HELLO, BOOST!
</pre>
