Question

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？

我从网站上的link provided下载了Boost。
提取到/devenv/boost160（我重命名原始文件夹后，/devenv/boost160是根目录）
我从./bootstrap.sh运行了/devenv/boost160（一切正常;根据他们的official documentation，运行此参数不带参数，将输出转换为/usr/local）并且顺利进行。
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()

我运行了CLion的 Build 命令，我得到了以下输出，基本上说它无法找到boost_asio。

在我的配置中如何在项目中使用Boost 1.60.0？谢谢！

Boost.Asio是一个仅限标头的库。用于定位Boost组件的标准CMake函数（FindBoost.cmake）仅考虑具有预构建库的组件作为组件，假设仅包含标头的组件与其余Boost标头一起安装完成。所以你应该使用find_package(Boost 1.60.0 REQUIRED date_time)（date_time实际上有预建库，可以通过FindBoost.cmake找到它。）

我说可以增强FindBoost.cmake以隐藏仅限标头库与应用程序开发人员真正的预构建库之间的差异。但是现在它是后者的责任。

编辑关于system_category的错误：您还需要Boost.System库，因此find_package调用应该看起来像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似乎仍然使用它自己的system_category实现，而后者是standardized in C++11

CMake无法找到boost_asio
