在使用Boost时，我遇到了一个问题，因为修改FindBoost.cmake正在搜索的编译器版本。默认情况下，它会搜索vc 140工具集，但我尝试在Visual Studio 2019和Visual Studio 2022中使用vc 142或vc 143工具集。
这是我的CMakeList.txt，我试图在其中为findboost设置正确的提示。不管我做什么，_boost_COMPILER仍然是vc 140。

set(BOOST_ROOT "D:/Bladesense/boost_1_82_0")

set(Boost_DEBUG ON)
set(Boost_COMPILER "-vc143")
set(BOOST_COMPILER  "-vc143")
set(_boost_COMPILER "-vc143")
message(STATUS "BOOST_COMPILER ${BOOST_COMPILER}")
message(STATUS "MSVC_TOOLSET_VERSION ${MSVC_TOOLSET_VERSION}")

find_package(Boost 1.82 REQUIRED COMPONENTS serialization filesystem system)

这是FindBoost调试输出（最后一行的relevant _boost_COMPILER）：

我不明白为什么_boost_COMPILER仍然是-vc 140。当我安装使用vc 140工具集编译的boost时，CmakeCache.txt正确生成：

然而，在构建过程中我得到了一个链接器错误。

我不明白为什么它试图链接libboost_filesystem-vc 142-mt-gd-x64-1_82.lib。libboost_filesystem-vc 140-mt-gd-x64-1_82.lib存在于目录中，并在CMakeCache.txt中指向。巧合的是，vc 142对应于我当前的msvc工具集版本。当我使用boost版本1.69或更低版本时，我得到了与libboost_filesystem-vc 141-mt-gd-x64-1_69.lib相同的链接器错误。
该问题在Boost版本1.55、1.69和1.82中仍然存在，使用自编译和预编译库。
作为解决这个问题的方法，我尝试使用vcpkg，它可以工作。但是，我需要vcpkg中没有的boost 1.55版本。
