Question

我正在尝试从源代码构建PCL，但是CMake无法找到某些库。但是，当我检查那里的图书馆。我知道这已经被问了很多，但是我只是从CMake开始，我已经在互联网上搜索了好几天，却找不到可行的解决方案。我觉得我缺少任何帮助将不胜感激的东西

所以我按照别人的建议在我的CMakeLists.txt中写了这个

cmake_minimum_required(VERSION 3.13)
set(Boost_ADDITIONAL_VERSIONS "1.67.0")
set(BOOST_ROOT "C:/local/boost_1_67_0/boost")

set(BOOST_INCLUDEDIR "C:/local/boost_1_67_0/")
set(BOOST_LIBRARYDIR "C:/local/boost_1_67_0/lib64-msvc-14.0")

set (Boost_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(Boost 1.67.0)

但是我仍然收到相同的错误：

     CMake Error at C:/Program Files/CMake/share/cmake-3.13/Modules/FindBoost.cmake:2100 (message):
  Unable to find the requested Boost libraries.

  Boost version: 1.67.0

  Boost include path: C:/local/boost_1_67_0

  Could not find the following static Boost libraries:

          boost_filesystem
          boost_thread
          boost_date_time
          boost_iostreams
          boost_system

  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):
  cmake/pcl_find_boost.cmake:36 (find_package)
  CMakeLists.txt:428 (include)

老实说，我会就目前可以尝试的事情提出建议。如果我可以提供我没有想到的任何其他有用信息，请随时发表评论或留言。谢谢

Answer 1

几个月前，我遇到了同样的问题。这解决了我的问题。

find_package(Boost 1.67.0 COMPONENTS system filesystem REQUIRED)
include_directories(${Boost_INCLUDE_DIRS})

Answer 2

像timko.mate建议的那样，find_package带有组件是正确的方法。

但是，您应该考虑使用基于目标的API：

target_link_libraries(your_exe PUBLIC Boost::system Boost::filesystem)

此外，要使CMake找到Boost，您应该调整前缀路径。通常是在项目中调用cmake时完成的：

cmake -DMAKE_PREFIX_PATH=c:/local/ ..

那样，您的cmake文件中不应包含任何硬编码路径。

CMake找不到Boost库文件tem，线程，date_time，iostreams，系统
