[ITK-dev] installed ITK cannot be moved due to absolute path

[Dženan Zukić]

Hi Rashad,

a few months ago relative paths were completely removed from CMake, because
they were never fully implemented. Have you followed recommendations from
here <https://itk.org/Wiki/ITK/Cross_Compiling> for cross-compiling?

As for integrating your changes into ITK, you should submit a patch
following the instructions here <https://itk.org/Wiki/ITK/Git/Develop>. If
your changes don't break anything, they are likely to be integrated.

Regards,
Dženan
