Integrating growl in c++ app

Isn't there a guide on how to integrate growl into a c++ application?
I've compiled the gntp-send source from github and I've got 

bin/
    gntp-send.exe
    gntp-send++.exe
lib/
    growl.dll
    growl++.dll
    libgrowl.dll
    libgrowl.exp
    libgrowl++.dll
    libgrowl++.exp
obj/
    gntp-send.obj
    gntp-send++.obj
    growl.obj
    growl++.obj
    md5.obj
    tcp.obj

I don't know which files I have to import to my project in order to use the c++ 
functions such as:

Growl *grow = new Growl( protocol , password , appname , notifications , 
notifications_count );
growl→Notify( notification1 , title , message );
growl→Notify( notification2 , title , message );

Also there is no information about what protocol, password, notifications and 
notifications_count are.

Could you please help me?
Thank you!
