mysql.h use #include "my_stmt.h" instead of <my_stmt.h>

The standard include path is /usr/include/
I copied all include files into /usr/inlude/mysql/, and my source code like this:

#include <mysql/mysql.h>

int main()

{

    return 0;

}

But mysql.h is including my_stmt.h with <> which will lead to compile error because my_stmt.h is not in standard include path /usr/include. see the code here: https://github.com/MariaDB/mariadb-connector-c/blob/master/include/mysql.h#L367
Should we use #include "my_stmt.h" instead of <my_stmt.h>?
