Error trying to install Qxt for sending email

I need to use the QxtSMTP module to be able to send email through Qt. I downloaded the package from here. As per the instructions, I did .configure and make. During make install, it threw an error - (OS X, 10.10)

/Users/Cupidvogel/Desktop/mail/libqxt-master/src/core/qxtglobal.cpp:201: Undocumented parameter 'PUB' in QXT_P()
/Users/Cupidvogel/Desktop/mail/libqxt-master/src/core/qxtglobal.cpp:201: No such parameter 'QXT_DECLARE_PUBLIC' in QXT_P()

make: *** [adp_docs] Error 134

As a result of which I am unable to get the libraries installed. How do I fix this?

And secondly, I need the header files and libraries required to send email. I don't want to do it the README file suggests - by configuring Qxt and CONFIG variables. So which libraries do I need to link?
