VTK Undefined Reference

I installed VTK 7.1.1 as suggested here.

I'm working on a new project with the following code:

#include <iostream>#include <vtk-7.1/vtkImageData.h>#include <vtk-7.1/vtkMetaImageReader.h>#include <vtk-7.1/vtkSmartPointer.h>#include <vtk-7.1/vtkRenderer.h>#include <vtk-7.1/vtkImageActor.h>#include <vtk-7.1/vtkImageMapper3D.h>#include <vtk-7.1/vtkRenderWindow.h>#include <vtk-7.1/vtkRenderWindowInteractor.h>int main(){    vtkSmartPointer<vtkMetaImageReader> reader =  vtkSmartPointer<vtkMetaImageReader>::New();    reader->SetFileName("Test.mhd");    reader->Update();    std::cout<<"Hello World";    return 0;}

I am using the following to compile:

g++ -g -Wall -I /usr/local/include -L /usr/local/lib -o main main.cpp

However, I keep getting errors such as the following:

/usr/local/include/vtk-7.1/vtkSmartPointer.h:29: error: undefined reference to `vtkSmartPointerBase::~vtkSmartPointerBase()'

Any idea as to why? I think it might be the linking maybe?
