CMake无法找到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.我从网站提供的链接下载了Boost。
2.解压到/devenv/boost160 ( /devenv/boost160是根目录，在我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, 运行此命令而不带参数，将输出到/usr/local)。
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()
我运行了CLion的Build命令，但却得到了如下输出，基本上是说它无法找到boost_asio。

在我的配置中，如何使用Boost 1.60.0？谢谢！

Boost.Asio 是一个仅包含头文件的库。标准的 CMake 函数用于定位 Boost 组件（FindBoost.cmake）只考虑预构建库作为组件，假设头文件组件已经与其余的 Boost 头文件一起安装完成。所以你应该使用 find_package(Boost 1.60.0 REQUIRED date_time) （date_time 实际上有预构建库，并且可以通过 FindBoost.cmake 定位）。

我认为 FindBoost.cmake 可以增强来隐藏应用程序开发人员在头文件库和真实的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：你还需要 Boost.System 库，因此 find_package 调用应该像这样： 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 似乎仍在使用自己的 system_category 实现，而后者已经在 C++11 中得到了标准化。

谢谢您的快速回复。我尝试了这个方法，但仍然出现错误：https://dpaste.de/TyWV - Victor
好的，你真是个天才！谢谢！ - Victor
