[Insight-developers] why can't a file in Modules/Filtering/DiffusionTensorImage/include find itkSpatialObject.h?

[Luis Ibanez]

A word of caution:


Please don't take lightly the act of adding new dependencies
between modules.


It took a lot of effort to untangle the matrix of dependencies
between ITK classes, and by adding dependencies we take
steps back to a monolithic ITK configuration.


Needs for new dependencies, may be indications of

1)  Misclassified classes
2)  Design flaws


I'm not saying that this particular new dependency is a problem,


Just want to make us aware that adding a dependency link
between two modules has large consequences and therefore
is something that must be done only after some discussion
among developers.
