Build error clear.

There is another link error when use libmariadb in poco.

In the file Poco/Data/MySQL/MySQL.h ,Line 57, poco link libmysql Automatically, On VS2017 will compile an error —— libmysql.lib not found，it seems need a patch when poco use libmariadb
//
// Automatically link Data library.
//
#if defined(_MSC_VER) && !defined(POCO_NO_AUTOMATIC_LIBS)
#if !defined(MySQL_EXPORTS)
#pragma comment(lib, "PocoDataMySQL" POCO_LIB_SUFFIX)
#endif
#pragma comment(lib, "libmysql")
#endif

Yes,I did poll. The error was happened on using poco library in my program. vcpkg auto link PocoData,PocoDataMySQL ,and poco will auto link libmysql.lib, not libmariadb.lib.
In file poco source code — poco/data/mysql/mysql.h

@yuntong613 Most dependencies are hard code in it's source files. Will fix today.

Windows and Linux would build well, and be easy to use.
