CMake is unable to find boost_asio

我正在尝试在我的新C++项目中安装和使用 Boost 1.60.0。（我使用 Ubuntu、CLion 和 CMake 进行开发和构建）。

我做了什么？

  1. 我从网站上提供的链接下载了 Boost。
  2. 提取到/devenv/boost160（/devenv/boost160是根，重命名原始文件夹后）
  3. 我从/devenv/boost160运行了./bootstrap.sh（一切顺利;根据他们的官方文档，在没有参数的情况下运行它，将输出带入/usr/local），并且进展顺利。
  4. 我创建了一个CLion项目，并将以下内容添加到CMakeLists.txt。
set(BOOST_ROOT /usr/local/include/boost)
set(BOOST_LIBRARYDIR /usr/local/lib)
set(Boost_USE_MULTITHREAD ON)
set(Boost_USE_STATIC_LIBS ON)
set(Boost_DEBUG ON)
find_package(Boost 1.60.0 REQUIRED COMPONENTS asio date_time)
IF (Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIR})
endif()
  1. 我运行了 CLion 的构建命令，得到了以下输出，基本上是说它找不到boost_asio。

如何在给定配置的情况下在项目中使用 Boost 1.60.0？谢谢！

Boost.Asio 是一个仅标头库。用于查找 Boost 组件的标准 CMake 函数 （FindBoost.cmake） 仅将具有预构建库的组件视为组件，假设仅标头组件与其余 Boost 标头一起完成安装。所以你应该使用find_package(Boost 1.60.0 REQUIRED date_time)（date_time实际上有预先构建的库，可以通过FindBoost.cmake找到）。

我想说的是，可以增强FindBoost.cmake，以隐藏仅标头库与应用程序开发人员的真实预构建库之间的差异。但现在这是后者的责任。

编辑 关于system_category的错误：您还需要 Boost.System 库，因此find_package调用应如下所示find_package(Boost 1.60.0 REQUIRED date_time system)，然后在 target_link_libraries 中使用Boost_SYSTEM_LIBRARY。不幸的是，Boost似乎仍然使用自己的system_category实现，而后者在C++11中被标准化
