Static linking help needed when including the viz module (VTK)
Hey all!
I'm having an issue I've been fighting with all weekend. I'm trying to build a fairly simple example which uses the viz module in C++. I've built OpenCV 3.4 and OpenCV-contrib along with VTK 8.1.0 as static libs and all seems to be well there. But after adding all the libs and appropriate includes I get 19 build errors I can't seem to resolve and they all seem to be related to the opengl libraries within vtk.

"unresolved external symbol" -> means you have included some Headers & corresponding linking is failing. Try to include opengl32.lib, glu32.lib in your project settings.
thanks that part I understood lol ;) Does glew need to be built along with VTK? I didn't see those lib files generated anywhere, I had thought VTK shipped with opengl libs built in.
These are OpenGL related libs that comes with your OS itself. You can find the path of those libs here
