# ITK 5.x is not fully compatible with ITK 4.x, so we package it separately.
# We can allow side-by-side installation by relying on ITK's versioned paths.
# However, we must be careful with binary names if there are tools included.
# This package focuses on the libraries for development.

%description
The Insight Toolkit (ITK) is an open-source, cross-platform system that provides
