Including libraries in c++ form

Including libraries in c++ form

I have been making console applications in c++ forever. Now i want to
switch over to making forms. So I was just wondering how I would include
other libaries. For example I wanted to make a program that had a function
involving time, in a console app i would put #include .... I want to know
what is the equivlance of this in a form. By the way, im using visual c++
