我如何安装库和cmake

Boost编译为：

bootstrap.bat
.\b2

和（因为我不知道区别；一个在boost / stage / lib下编译；第二个在boost / lib下编译）

bjam install --prefix=D:/Programme/Boost/boost_1_69_0 --with-system --with-date_time --with-random link=static runtime-link=shared threading=multi

我在path下的系统变量中添加了所需的路径。

environment variables

Path

尝试使用cmake进行构建时，出现以下错误：

  For compatibility, CMake is ignoring the variable.
This warning is for project developers.  Use -Wno-dev to suppress it.

  Could not find the following Boost libraries:

  No Boost libraries were found.  You may need to set BOOST_LIBRARYDIR to the
  directory containing Boost libraries or BOOST_ROOT to the location of
  Boost.

在我看来，除了Boost以外的所有东西都可以正常工作。我知道有几个用户遇到此问题，例如：

Cmake doesn't find Boost

CMake with Boost could not find static libraries

CMake with Boost library Windows 10 Library not found correctly

因此，我执行了建议的步骤：

SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "D:/Programme/Boost/boost_1_69_0")
SET(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} "D:/Programme/Boost/boost_1_69_0/lib")

FIND_PACKAGE(Boost)
IF (Boost_FOUND)
    INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIR})
    ADD_DEFINITIONS( "-DHAS_BOOST" )
ENDIF()

和

set(BOOST_LIBRARYDIR D:/Programme/Boost/boost_1_69_0/lib)

没有任何效果。我绝对不知道该做什么，因为几天来拼命地试图弄清楚该怎么做才能成功。请帮帮我。

Answer 1

根据您的评论，Boost的位置为D:/Programme/Boost/boost_1_69_0/stage/lib，但您将其设置为D:/Programme/Boost/boost_1_69_0/lib。

无论如何，如果您使用BOOST_ROOT将D:/Programme/Boost/boost_1_69_0设置为FIND_PACKAGE(Boost)（通常是在CMake UI中而不是在CMakeLists.txt文件中手动设置），则可以找到Boost。

这将依次设置您需要使用的所有Boost_*变量。

Answer 2

使用相同的命令来构建和安装Boost。

bjam install --prefix=D:/Programme/Boost/boost_1_69_0 --with-system --with-date_time --with-random link=static runtime-link=shared threading=multi

在Windows中，Boost在include下创建另一个子目录。应该是这样的。

D:/Programme/Boost/boost_1_69_0/include/boost-1_69

将D:/Programme/Boost/boost_1_69_0/include/boost-1_69中的所有文件移动到D:/Programme/Boost/boost_1_69_0/include/

（将内容上移至一个目录）

现在将CMake项目中的BOOST_ROOT设置为D:/Programme/Boost/boost_1_69_0。

现在应该可以工作。

找不到以下Boost库：boost_system
