It is, I will see if I can reproduce. I don't even see where
EIGEN_INCLUDE_DIR would get defined, and how it would solve any
problem. A git grep for it in the source tree turns up nothing, and we
should consistently choose Eigen 2 or 3 - mixing the two would not end
well.Thanks for your feedback, I will try to dig a little deeper when I have some time and see if we can clean things up a little more.
