我遇到了奇怪的conan问题。我的conanfile.txt读为：
[requires]
boost/1.71.0@conan/stable
[generators]
cmake
从构建目录运行conan install ..时，我收到以下消息：
boost/1.71.0@conan/stable: WARN: Lib folder doesn't exist, can't collect libraries: /root/.conan/data/boost/1.71.0/conan/stable/package/f419497daccab81a781a793e5fffd7f228cf234e/lib
boost/1.71.0@conan/stable: LIBRARIES: []
boost/1.71.0@conan/stable: Package folder: /root/.conan/data/boost/1.71.0/conan/stable/package/f419497daccab81a781a793e5fffd7f228cf234e
cd进入柯南软件包安装目录，没有库（如消息所警告）。头文件不完整，只有3-4个目录。多次这样做会产生相同的结果。我在做什么错了？
