    COMP: Add ITKFactoryRegistration library centralizing ITK IO factory registration · 03b89614
    jcfr authored
    This commit will ensure that ITK IO factory are properly registered on all
    supported platforms.
    
    When ITKv4 is build shared, the library holding the factory registration code
    are build statically. As a consequence, when CLI module are loaded as library
    the factory are registered multiple times. Around 800 factories where registered
    and this was leading to poor performance when loading images.
    
    This commit enable the building of a shared library named ITKFactoryRegistration
    that should be linked against to ensure loading of the factory. This approach
    can succeed thanks to the help of the ITK variable ITK_NO_IO_FACTORY_REGISTER_MANAGER.
    
    This variable allow to disable the automatic registration of factory in selected part
    of the code.
    
    The following two cases are handled:
     - Registration of the factories within the Slicer executable.
     - Registration of the factories within CLI executable.
    
    Fixes #2813
