[vtkusers] vtk memory leaks?

[Alex Malyushytskyy]

I am not sure enabling VTK_DEBUG_LEAKS for a single project will help.
Personally I enabled appropriate option in CMAKE when building VTK.
It does work for a version I am working with (5.8.0 )

It is easy to check. Write a simple program  (get any test) which
instantiate any vtkObject subclass and exit.
If you do not see message box with leaks report your vtk is not configured
right.
AFAIK there were some changes in later version, so comments above may not
be relevant to your version though.

I do not think delay load option may affect this. All you need is to make
sure they are loaded before any vtk object is instantiated.
To be sure load them normally for test purposes.

Regards,

Alex
