Description:
I wrote my own MySQL plugin by vs2015 vc++, if I reference sql_embedded.lib, my program would have link error: 
1>sql_embedded.lib(sql_builtin.obj) : error LNK2001: unresolved external symbol _builtin_csv_plugin
1>sql_embedded.lib(sql_builtin.obj) : error LNK2001: unresolved external symbol _builtin_heap_plugin
1>sql_embedded.lib(sql_builtin.obj) : error LNK2001: unresolved external symbol _builtin_innobase_plugin
1>sql_embedded.lib(sql_builtin.obj) : error LNK2001: unresolved external symbol _builtin_myisammrg_plugin
1>sql_embedded.lib(sql_builtin.obj) : error LNK2001: unresolved external symbol _builtin_archive_plugin
1>sql_embedded.lib(sql_builtin.obj) : error LNK2001: unresolved external symbol _builtin_blackhole_plugin
1>sql_embedded.lib(sql_builtin.obj) : error LNK2001: unresolved external symbol _builtin_partition_plugin
1>sql_embedded.lib(sql_builtin.obj) : error LNK2001: unresolved external symbol _builtin_ngram_parser_plugin

How to repeat:
I have checked MySQL source code(sql_builtin.cc):

#ifdef _MSC_VER
extern "C"
#else
extern
#endif
builtin_plugin 
    builtin_csv_plugin,  builtin_heap_plugin,  builtin_innobase_plugin,  builtin_myisam_plugin,  builtin_myisammrg_plugin, 
#ifndef EMBEDDED_LIBRARY
   builtin_perfschema_plugin,
#endif
   builtin_archive_plugin,  builtin_blackhole_plugin,  builtin_partition_plugin,  builtin_ngram_parser_plugin, builtin_binlog_plugin, builtin_mysql_password_plugin;

since it is using extern, but I have searched all cpp,cc.hpp,h file, I didn't find where builtin_csv_plugin is defined.
So I was wondering how could I resolve this issue, thanks
