使用CMake引入Boost UUID模块时遇Boost::assert依赖缺失问题求助

Boost的uuid模块依赖多个基础header-only模块（如assert、config、core等），这些模块不会自动作为uuid仓库的子模块引入，可通过以下两种方式解决：

方法1：手动添加Git子模块 #

1. 在项目根目录执行命令，将uuid依赖的模块添加为子模块：

git submodule add https://github.com/boostorg/assert third-party/assert
git submodule add https://github.com/boostorg/config third-party/config
git submodule add https://github.com/boostorg/core third-party/core
git submodule add https://github.com/boostorg/predef third-party/predef
git submodule add https://github.com/boostorg/throw_exception third-party/throw_exception

（注：建议所有模块使用同一Boost版本标签，比如boost-1.84.0，替换命令中的默认分支）

2. 修改项目的CMakeLists.txt，先添加依赖模块，再添加uuid模块：

# 先引入所有依赖的Boost基础模块
add_subdirectory(third-party/assert)
add_subdirectory(third-party/config)
add_subdirectory(third-party/core)
add_subdirectory(third-party/predef)
add_subdirectory(third-party/throw_exception)

# 再引入uuid模块
add_subdirectory(third-party/uuid)

# 链接到你的项目目标
target_link_libraries(your_project_target PRIVATE Boost::uuid)

方法2：用CMake FetchContent自动拉取依赖 #

无需手动管理子模块，CMake会自动下载并配置所有依赖：

include(FetchContent)

# 定义需要拉取的Boost模块，指定仓库和版本标签
FetchContent_Declare(
  boost_assert
  GIT_REPOSITORY https://github.com/boostorg/assert
  GIT_TAG boost-1.84.0 # 替换为你需要的Boost版本
)

FetchContent_Declare(
  boost_config
  GIT_REPOSITORY https://github.com/boostorg/config
  GIT_TAG boost-1.84.0
)

FetchContent_Declare(
  boost_core
  GIT_REPOSITORY https://github.com/boostorg/core
  GIT_TAG boost-1.84.0
)

FetchContent_Declare(
  boost_predef
  GIT_REPOSITORY https://github.com/boostorg/predef
  GIT_TAG boost-1.84.0
)

FetchContent_Declare(
  boost_throw_exception
  GIT_REPOSITORY https://github.com/boostorg/throw_exception
  GIT_TAG boost-1.84.0
)

FetchContent_Declare(
  boost_uuid
  GIT_REPOSITORY https://github.com/boostorg/uuid
  GIT_TAG boost-1.84.0
)

# 自动下载、配置并构建所有依赖
FetchContent_MakeAvailable(boost_assert boost_config boost_core boost_predef boost_throw_exception boost_uuid)

# 链接到你的项目目标
target_link_libraries(your_project_target PRIVATE Boost::uuid)

两种方法都能让CMake找到Boost::assert等依赖目标，无需安装完整Boost库。
