[Insight-developers] strange error with export list on modular ITK

[Alexandre GOUAILLARD]

ok, good news and bad news,

I like my dessert first: I fixed it. However it requires modification
in DCMTK itself to make its targets exportable to an external
"superbuild".

steve, stephen, could you help me contact the DCMTK guys to transfer
those changes (it should be backward compatible) ?

On to the ImageIO itself now.
