I met a bug when I was compiling the example for visualizing histgram on PCL/OpenNI tutorial 4: 3D object recognition (descriptors) - robotica.unileon.es[^] using PCLHistogramVisualizer with vs 2022.
There is a vital link problem: error LNK2019: unresolved external symbol "public:_cdecl pcl::visualization::RenWinInteract::RenWinInteract(avoid)".

What I have tried:

The codes in my project for visualization are:
pcl::visualization::PCLHistgramVisualizer viewer;
viewer.addFeatureHistogram(*descriptor, 308); // for vfh descriptor;
viewer.spin();

So go back to where you go the code, and ask there: they will have a much better idea how their code works - or should be compiled - than we would.

At a guess - and that's all we could give you - you aren't linking a necessary library when you build the project: check for a makefile and use that.
