[vtkusers] vtkStandardNewMacro Issue?

[Alessandro]

I didn't understand. Do I need to write down something like that in the MyCustomInteractorStyle.cxx?


MyCustomInteractorStyle * MyCustomInteractorStyle::New() {
}

Then this object should be linked to everything else by the linker. Which file in your project does the MyCustomInteractorStyle::New() appear in? And can you show us the add_executable and target_link_libraries lines of your CMakeLists.txt?
