Hello,

I’m trying to render volume data using c++ / vs2015 / vtk master (I cloned it from github and built it in vs2015), but I’m getting a linker error when calling the method vtkVolume::SetProperty  
These are the lines of code I’m using:

```
#include <vtkVolume.h>
#include <vtkVolumeProperty.h>
#include <vtkPiecewiseFunction.h>
#include <vtkColorTransferFunction.h> 
#include <vtkProperty.h> 
..
..
..
vtkSmartPointer<vtkVolumeProperty> volumeProperty = vtkSmartPointer<vtkVolumeProperty>::New();
volumeProperty->SetInterpolationTypeToLinear();
 volumeProperty->SetIndependentComponents(true);
vtkSmartPointer<vtkColorTransferFunction> colorFun = vtkSmartPointer<vtkColorTransferFunction>::New();
  volumeProperty->SetColor(colorFun);
vtkSmartPointer<vtkVolume> volume = vtkSmartPointer<vtkVolume>::New()
volume->SetProperty(volumeProperty);

```

The compiler error is  
Main.obj : error LNK2019: unresolved external symbol “\_\_declspec(dllimport) public: void \_\_cdecl vtkVolume:: **SetProperty** (class vtkVolumeProperty \*)” (\__imp_?SetPropertyvtkVolumeQEAAXPEAVvtkVolumePropertyZ) referenced in function “public: virtual void \_\_cdecl MyVRApp::onRenderGraphicsContext(class MinVR::VRGraphicsState const &)” (?onRenderGraphicsContextMyVRAppUEAAXAEBVVRGraphicsStateMinVRZ)

Yes! I added the libraries to the vs linker (properties-\>linker-\>input and properties-\>linker-\>Additional Library Directories).  
This is the log from the linker in verbose mode. I believe vtkvolume is in the vtkRenderingCore lib, but you’ll see although the linker finds it, it doesnt find the mentioned method:

Do you know what I could be missing?

Thanks for the help.

I checked only the library folder path and not the include folder path. I was pointing to an unknown place.
