Hi and welcome to devnet,

It's described here in the Qt documentation.

And if you are using Qt Creator, you can also follow the documentation here.

Thanks for your reponse,

I added to pro file this:
INCLUDEPATH += /usr/local/include/openbabel-2.0
LIBS += -L /usr/local/lib/libopenbabel.dylib

Now I can include classes from this library but now I have other issues:

:-1: warning: -L path '/usr/local/lib/libopenbabel.dylib' is not a directory
:-1: error: symbol(s) not found for architecture x86_64
:-1: error: linker command failed with exit code 1 (use -v to see invocation)

I am not able to fix it anyway, what´s wrong?

Thank you very much!

As explained in the documentation, the -L parameter is to add folders the list of paths searched by the linker.

So to be correct:

LIBS += -L/usr/local/lib/ -lopenbabel
