[Insight-users] WrapItk: How to enable the typemap for itk::Mesh in external projects?

[Gaetan Lehmann]

Hi,

First of all, thanks for your interest for WrapITK :-)

Can you send me (off list) all the files of your project ?
I would be please to test it, and debug WrapITK if needed :-)

Thanks,

Gaetan
