什么是正确的方法链接Boost与CMake和Visual Studio在Windows中？ [英] Whats the proper way to link Boost with CMake and Visual Studio in Windows?

问题描述

我想为Visual Studio 2012生成一些我需要的Boost 1.58库（chrono，regex和thread），并将库链接到CMake。我有真正的问题为CMake和Visual Studio找到或链接的libs，这取决于我设置的配置。

我最后使用以下配置：

bjam.exe --link = static --threading multi --variant = debug阶段

生成静态库。

我应该如何生成库并用CMake搜索它们，以便Visual Studio正确链接它们？

我已经提出了一个解决方案， > Visual Studio搜索动态库，因此我们需要将Boost库编译为共享，多线程，调试和发布，以及运行时链接共享。在windows中使用bjam.exe所有命令都有前缀 - 除了链接，所以正确的方法来构建库是：

  bjam.exe link = shared --thread = multi --variant = debug --variant = release --with-chrono --with-regex --with-thread阶段
  
 
 
 
这将在文件夹Boost / stage / lib中生成libs和DLL，因此我们需要设置一个环境变量Boost_LIBRARY_DIR C：/ Boost / stage / 
 
 
 
 $ b 
有更多的选择可能来自：
 <$> c $ c> runtime-link = shared / static 
 toolet = msvc-11.0 
  
库将有这样的名称发布：
  boost_chrono-vc110-mt-1_58.lib 
 boost_chrono-vc110 -mt-1_58.dll 
  
并且用于调试：
  boost_chrono-vc110-mt-gd-1_58.lib 
 boost_chrono-vc110-mt-gd-1_58.dll 
  
 
 
 
为了使CMake正确链接它们，我们需要在CMakeLists.txt中编写以下内容：
  add_definitions（-DBOOST_ALL_DYN_LINK）//如果没有VS会给出重定义的链接错误
 set（Boost_USE_STATIC_LIBS OFF）
 set（Boost_USE_MULTITHREADED ON）
 set（Boost_USE_STATIC_RUNTIME OFF）
 find_package（Boost COMPONENTS thread chrono regex REQUIRED）
 
 INCLUDE_DIRECTORIES（$ {Boost_INCLUDE_DIRS}）
 
 TARGET_LINK_LIBRARIES（$ {PROJ_NAME} $ {Boost_LIBRARIES }）
  
 
I am trying to generate some Boost 1.58 libraries that I need (chrono, regex and thread) for Visual Studio 2012 and link the libraries with CMake. I have real problems for CMake and Visual Studio to find or link the libs, depending on the configuration I set.

I am finally using the following configuration:

bjam.exe --link=static --threading multi --variant=debug stage

But this doesn't seem to generate static libs.

How should I generate the libs and search them with CMake in order for Visual Studio to link them properly?
解决方案
I finally came up with the solution and I think it is detailed enough to become a generic answer.

Visual Studio searches for dynamic libraries so we need to compile Boost libraries as shared, multithreaded, debug and release,  and runtime-link shared. In windows using bjam.exe all commands have the prefix "--" except link, so the right way to build the libraries is:
bjam.exe link=shared --threading=multi --variant=debug --variant=release --with-chrono --with-regex --with-thread stage
This will generate the libs and DLLs in the folder Boost/stage/lib, so we need to set an environment variable Boost_LIBRARY_DIR C:/Boost/stage/lib, for example.

There are more options that may come in hand:
runtime-link = shared/static
toolset= msvc-11.0
The libraries will have a name like this for release: 
boost_chrono-vc110-mt-1_58.lib
boost_chrono-vc110-mt-1_58.dll
And for debug: 
boost_chrono-vc110-mt-gd-1_58.lib
boost_chrono-vc110-mt-gd-1_58.dll
In order for CMake to link them properly we need to write the following in the CMakeLists.txt:
    add_definitions( -DBOOST_ALL_DYN_LINK )  //If not VS will give linking errors of redefinitions
    set(Boost_USE_STATIC_LIBS OFF )
    set(Boost_USE_MULTITHREADED ON)
    set(Boost_USE_STATIC_RUNTIME OFF)
    find_package(Boost COMPONENTS thread chrono regex REQUIRED )

    INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})

    TARGET_LINK_LIBRARIES( ${PROJ_NAME} ${Boost_LIBRARIES} )
