  Target "image-stitching" links to target "Eigen3::Eigen" but the target was
  not found.  Perhaps a find_package() call is missing for an IMPORTED
  target, or an ALIAS target is missing?

Thanks for finding it out!

Turned out that this Eigen3::Eigen target was introduced since eigen 3.3.1: http://eigen.tuxfamily.org/index.php?title=ChangeLog#Eigen_3.3.1
