因此，在安装VS 2022并下载和编译boost 1.82之后，我试图运行一个测试项目，一个应该编译跨平台的项目(VS 2022的新功能或者在以前的版本中也有??)。我创建了一个新的vc++项目和解决方案，从VS文件>新比;项目比;CMake项目。
然后将CMakeLists.txt文件修改为:
...
set (BOOST_ROOT "C:/boost/boost")
set (BOOST_INCLUDEDIR "C:/boost/boost/include")
set (BOOST_LIBRARYDIR "C:/boost/boost/stage/lib")
set (BOOST_MIN_VERSION "1.82.0")
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
set(Boost_DEBUG ON)
find_package(Boost ${BOOST_MIN_VERSION} COMPONENTS date_time REQUIRED)
if (NOT Boost_FOUND)
message(FATAL_ERROR "Fatal error: Boost (version >= ${BOOST_MIN_VERSION}) required.")
endif()
include_directories(${Boost_INCLUDE_DIRS})
link_directories(${Boost_LIBRARY_DIRS})
...
然后是Project>删除缓存并重新配置
问题是它无法找到boost库，我相信这是因为它无法找出编译器是什么:

这里_boost_COMPILER被检测为_boost_COMPILER = "" (guessed)。
你知道这里有什么问题吗?VS应该告诉CMake关于自己的权利，因为我从内部调用CMake ?

在浏览了整个日志之后，问题似乎不在您预期的地方。

find_package(Boost ${BOOST_MIN_VERSION} COMPONENTS date_time REQUIRED) #<---
...
日志底部是这么写的:
#Missing date_time... i.e. it can't find a REQUIRED component
1> [CMake] Could NOT find Boost (missing: date_time) (found suitable version "1.82.0",
1> [CMake] minimum required is "1.82.0")
为了正确调试这个问题，我建议检查这些变量输出的路径:
1> [...] _boost_LIBRARY_SEARCH_DIRS_RELEASE = "C:/boost/boost/stage/lib;C:/boost/boost/lib;C:/boost/boost/stage/lib;C:/boost/boost/lib;C:/boost/boost/../lib;C:/boost/boost/stage/lib;PATHS;C:/boost/lib;C:/boost;/sw/local/lib"
1> [...] _boost_LIBRARY_SEARCH_DIRS_DEBUG = "C:/boost/boost/stage/lib;C:/boost/boost/lib;C:/boost/boost/stage/lib;C:/boost/boost/lib;C:/boost/boost/../lib;C:/boost/boost/stage/lib;PATHS;C:/boost/lib;C:/boost;/sw/local/lib"
并仔细检查这些库是否存在于目录中(它们可能不会)
1> [...] Searching for DATE_TIME_LIBRARY_RELEASE: libboost_date_time-mt-1_82;libboost_date_time-mt;libboost_date_time-mt;libboost_date_time-mt;libboost_date_time
1> [...] Searching for DATE_TIME_LIBRARY_DEBUG: libboost_date_time-mt-d-1_82;libboost_date_time-mt-d;libboost_date_time-mt-d;libboost_date_time-mt;libboost_date_time
然后我会检查这些库是否存在于boost文件夹中。很可能它们不会，而且很可能是因为它们要么是不同组件的一部分，要么只是在您的boost安装中丢失了。
尝试包含整个boost，看看是否是这种情况:
find_package(Boost ${BOOST_MIN_VERSION})
希望有帮助!
编辑:我已经成功地复制了你的问题，这确实是由于未检测到的编译器最有可能。与构建boost时一样，它将编译器作为后缀(或中间名称)附加到库中。也就是说，如果你检查lib目录，你可以推断出正在使用哪个编译器，也许可以通过set(Boost_COMPILER "-vcXYZ")强制设置变量。
注意，libboost_date_time-mt-d-1_82是缺少编译器由于这个未设置的变量。它应该看起来像libboost_date_time-vc142-mt-d-1_82(如果使用vc142编译)
