更新

在评论添加context to reproduce问题后，我找到了原因。
原因是FETCHCONTENT_TRY_FIND_PACKAGE_MODE默认为OPT_IN，这意味着find_package被调用，因为FIND_PACKAGE_ARGS存在。这会找到声明：：headerstarget的系统Boost包。 有两种方法可以解决这个问题： 1.删除FIND_PACKAGE_ARGS，参考[docs](https://cmake.org/cmake/help/latest/module/FetchContent.html)： 此选项适用于FetchContent_MakeAvailable()命令可能首先尝试调用find_package()以满足的依赖关系的情况 1.在内容声明之前将FETCHCONTENT_TRY_FIND_PACKAGE_MODE设置为NEVER`：

SET(FETCHCONTENT_TRY_FIND_PACKAGE_MODE NEVER)
FetchContent_Declare(
    Boost
    URL https://github.com/boostorg/boost/releases/download/boost-1.83.0/boost-1.83.0.7z
    USES_TERMINAL_DOWNLOAD TRUE
    DOWNLOAD_NO_EXTRACT FALSE
    FIND_PACKAGE_ARGS COMPONENTS ${BOOST_INCLUDE_LIBRARIES}
)
FetchContent_MakeAvailable(Boost)

型
注意事项：

• 如果find_package在fetchcontent包填充之前找到Boost，则添加OVERRIDE_FIND_PACKAGE不会执行任何操作-例如，此操作失败：https://coliru.stacked-crooked.com/a/55451090f10cffa7
• FetchContents_Declare**点处FETCHCONTENT_TRY_FIND_PACKAGE_MODE**的值是重要的
