How can third module which written in C++ used in Blueprint

Hi,I hava a problem.I write a c++ module in vs2015IDE, just like this link [c++] Mysql database error - C++ - Epic Developer Community Forums
Everything is ok,and build suscessfully.
MyQuestion is how it can be used in blueprint. just let the MySQLTest class in the link of website be seen in blueprint?
When I compile the code in the ue4 editor, it alway tell me ‘mysql.h’ no such file!

Hey,I‘m using it as plugin, solved it!

I meet that problem too. Have you solved it?
