I have followed various tutorials including one where I build it with QT

and building it as a standalone

martijnkoopman/Qt-VTK-viewer/blob/master/doc/Build-VTK.md

# Building VTK 9.0 with Qt 5.15
This guide will help you build VTK 9.0 with Qt 5.15. 
This procedure has been tested on Windows 10 and Debian-based Linux.

## Prerequisites
- CMake 3.8+ installed

- Qt 5.x downloaded. 
The Qt directory will be refered to as \<QT-DIR\>

- C++ compiler installed (like  GCC or  VS 2019). 
The compiler name will be refered to as \<COMPILER\>

## Building VTK
**1. Download VTK source code**

Download the source code from [http://VTK.org/download/](http://www.vtk.org/download/) and unpack it to a directory. This directory will be refered to as \<VTK-SOURCE-DIR\>

**2. Start CMake**

This file has been truncated. show original

or running a stand alone application without QT

I even just copy and pasted the sample from here:
https://kitware.github.io/vtk-examples/site/Cxx/GeometricObjects/CylinderExample/

But everytime i run an application including the one from above, i get CRASHES on mere declaration alone.

here is the crash when using the CylinderExample from above.

I tried building the latest 9.1.0 and even the version before that VTK-8.2.0
I cant seem to make it work!

when using QT, and declaring a QVTKOpenGLWidget, the crash is in the constructor itself, Exception occured yada yada.

What am i doing wrong to get myself started with VTK?
this is just sad, I already spent a whole day just setting this one up

This most commonly happens when your test application finds some unrelated VTK DLLs in your path.

In general, it is advisable to keep your PATH environment variable mostly empty (have nothing but some Windows system folders). If you want to make sure your executable does not pick up unrelated DLLs then you can put the DLLs in the same folder as the executable, or use manifests.
