伙计们，我在这里遇到了一些小问题。基本上，我试图用CMake来构建这个美好的库https://github.com/socketio/socket.io-client-cpp。使用boost库构建socket.io C++
首先，我根据需要安装了boost，并将其设置为opt/local/include/boost和opt/local/lib。但问题是CMake无法找到所需的增强库。 Configure后CMake的给我的日志：
not define build type, set to release
CMake Error at /Applications/CMake.app/Contents/share/cmake-3.6/Modules/FindBoost.cmake:1753 (message):
Unable to find the requested Boost libraries.
Boost version: 1.59.0
Boost include path: /opt/local/include
Could not find the following static Boost libraries:
boost_date_time
boost_random
Some (but not all) of the required Boost libraries were found. You may
need to install these additional Boost libraries. Alternatively, set
BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT
to the location of Boost.
Call Stack (most recent call first):
CMakeLists.txt:23 (find_package)
有一次，我遇到这个问题，我试图在手中设置BOOST_LIBRARYDIR，但也不能工作。
这里的CMake的文件与库中去，我不成功试图编译：

我在这里感谢所有帮助，伙计们！还有一个观察：如果我没有错，它试图找到boost_random当在include文件夹中它有名字random。也许这就是问题所在？
看起来你的增强安装是不完整的（'无法找到以下静态Boost库：'）。 – nightuser
确保已经静态构建Boost库（默认情况下可以禁用它）。 – nightuser
