如何處理“ Cmake錯誤：無法找到請求的Boost庫”？

Question

我正在嘗試在Windows10環境中構建此項目https://github.com/DLuensch/StereoVision-ADCensus 。 事實證明，我需要建立openCV，boost，libConfig，PCL，OpenMP，Qt 4.8X。 我真的不知道所有這些庫是什么，但是，我只是按照提供的說明進行操作。 當我嘗試使用cmake ..命令構建項目時，CMake引發錯誤“無法找到請求的Boost庫”，如下所示

我對CMake或BOOST不太熟悉。 實際上，直到昨天我才認識他們。 因此，我無法清楚地找出問題所在。

首先，我搜索了BOOST路徑中的文件，是的，沒有名為“ boost_filesystem”或“ boost_system”的文件。 我懷疑我的增強版是否不匹配。 然后，我查看了“ CMakeLists.txt”文件。 我發現這樣的聲明

# 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})

這是否意味着我應該使用BOOST 1.47.0（我現在下載了1.70.0）？ 並且，“ set（Boost_NO_BOOST_CMAKE ON）”是否意味着我甚至可以在沒有CMake的情況下構建該項目？ 因為我認為CMake的關閉進度失敗是因為不是缺少BOOST，而是因為PCL（我還沒有嘗試處理）。 如果我可以跳過有關BOOST問題的處理，那么我想，因為我有點着急。 還是我必須解決這個問題？ 希望獲得幫助。 提前致謝 ：）

cmake只是存在一個問題，即找不到升壓庫文件boost_filesystem和boost_system與您已安裝的boost版本鏈接。

cmake需要將BOOST_LIBRARYDIR設置為存儲庫文件的目錄，就像將BOOST_ROOT設置為安裝boost的目錄一樣。

安裝boost時，默認情況下不構建boost庫文件，請參見： boost：准備使用庫二進制文件 。 你可以建立自己的圖書館，描述在這里 。 但是，從此處下載並安裝相關的二進制文件更加容易。

注意： CMakeLists.txt文件行：

find_package(Boost 1.40.0 COMPONENTS filesystem system REQUIRED)

需要最低 boost版本1.40.0。 您應該對Boost版本1.70沒問題，除非發生了一些更改，從而破壞了向后兼容性。
CMakeLists.txt文件中引用的1.40和1.47版本非常舊...
