[Debian-med-packaging] Bug#698386: Is there a future for ITKSNAP?

[Paul Yushkevich]

Thanks, Gert,

A quick question about the plugins: when you build with Cmake, did you have
CMAKE_PREFIX_PATH set to point to the Qt5's lib/cmake directory? I think
this is the way the plugins get picked up.

I've set up a VM with Debian and am trying to build everything now.
