如何处理“ Cmake错误:无法找到请求的Boost库”?

我正在尝试在Windows10环境中构建此项目https://github.com/DLuensch/StereoVision-ADCensus。事实证明,我需要建立openCV,boost,libConfig,PCL,OpenMP,Qt 4.8X。我真的不知道所有这些库是什么,但是,我只是按照提供的说明进行操作。 当我尝试使用cmake ..命令构建项目时,CMake引发错误“无法找到请求的Boost库”,如下所示

我对CMake或BOOST不太熟悉。实际上,直到昨天我才认识他们。因此我无法清楚地找出问题所在。

首先,我搜索了BOOST路径中的文件,是的,没有名为“ boost_filesystem”或“ boost_system”的文件。我怀疑我的增强版是否不匹配。 然后,我查看了“ CMakeLists.txt”文件。我发现

这样的语句
# Under Windows the system variable "BOOST_ROOT" must be set to the location of the root directory of Boost.
if(WIN32)
  set(Boost_USE_STATIC_LIBS ON)
  set(Boost_USE_STATIC ON)
endif(WIN32)
SET(Boost_ADDITIONAL_VERSIONS "1.47" "1.47.0")
set(Boost_NO_BOOST_CMAKE ON)
find_package(Boost 1.40.0 COMPONENTS filesystem system REQUIRED)
set(BOOST_FOUND ${Boost_FOUND})
set(BOOST_INCLUDE_DIRS "${Boost_INCLUDE_DIR}")
set(BOOST_LIBRARY_DIRS "${Boost_LIBRARY_DIRS}")
set(BOOST_LIBRARIES ${Boost_LIBRARIES})
INCLUDE_DIRECTORIES(${BOOST_INCLUDE_DIRS})
SET(LIBS ${LIBS} ${Boost_FILESYSTEM_LIBRARY} ${Boost_SYSTEM_LIBRARY} ${Boost_DATE_TIME_LIBRARY})

这是否意味着我应该使用BOOST 1.47.0(我现在下载了1.70.0)? 并且,“ set(Boost_NO_BOOST_CMAKE ON)”是否意味着我甚至可以在没有CMake的情况下构建该项目?因为我认为CMake的关闭进度失败是因为不是缺少BOOST,而是因为PCL(我还没有尝试处理)。 如果我可以跳过有关BOOST问题的处理,那么我想,因为我有点着急。还是我必须解决这个问题?希望获得帮助。在此先感谢:)

cmake的一个问题是,它找不到增强库文件boost_filesystemboost_system来链接到已安装的boost的版本。

cmake需要将BOOST_LIBRARYDIR设置为存储库文件的目录,就像将BOOST_ROOT设置为安装boost的目录一样。

在安装boost时,默认情况下未构建boost库文件,请参见:boost: prepare to use a library binary。您可以自己构建库,如here所述。但是,从here下载并安装相关的二进制文件会更容易。

注意:CMakeLists.txt文件行:

find_package(Boost 1.40.0 COMPONENTS filesystem system REQUIRED)

需要最低版本 boost 1.40.0。除非发生了某些改变而导致向后兼容的问题,否则您应该对Boost 1.70感到满意。
CMakeLists.txt文件中引用的1.40和1.47版本是非常旧...
