In C++ and in C you have to specify the location of function declaration
you use (it's the headers files) and the location of the function
implementation (it's the library files).
If you look at the SCardEstablishContext function help, you will see
these two things.
The library to link against is : winscard.lib. The libraries are set in
your project properties.
