我在构建 SOCI 库时遇到了困难。
相关软件：
- 增强版 1.73.0
- CMake 版本 3.16
- MSVC 编译器版本 19.26.28805.0
- MySQL 5.7 版
- SOCI 版本 4.0.0
相关路径：
- 升压路径是
E:\cpp\Lib\boost\boost_1_73_0。 - CMake 的路径是
E:\Apps\CMake\share\cmake-3.16. - MySQL 服务器的路径是
C:\Program Files\MySQL\MySQL Server 5.7\. - MSVC 的路径是
C:\Apps\32\Microsoft\Visual Studio\2019\Community\VC\Tools\MSVC\14.26.28801\bin\Hostx64\x64.
建立 SOCI 的命令是cmake -DCMAKE_BUILD_TYPE=Debut -DSOCI_CXX11=ON -DSOCI_SHARED=ON -DWITH_BOOST=ON -DWITH_MYSQL=ON ..
这是修改后的Boost.cmake文件，位于%SOCI%\cmake\dependencies\. 评论开始##解释变化。

这是相关的输出。此处提供完整输出。

执行msbuild.exe SOCI.sln产生输出可用here。
谁能告诉我为什么 SOCI 不能正确构建？date_time为什么当它肯定存在时却找不到该组件？
