[Insight-developers] ITK 4.2.1: LoadDynamicFactories is not called?

[Bradley Lowekamp]

Hello Fabian,

With the modularization of the IO libraries with ITK v4 a new solution was needed to register all the factories in a modular fashion.

With the standard supported CMake using of the ITK package[1], the factory registration should still automatically happen. The registration is done threw static initialization, by header files that are automatically generated and including when using ITK with cmake [2].


It's rather a complicated automatic process that just works, and generally the details don't need to be worried about.

Brad

Or am I missing something?
