# hack alert!
# something defines the Eigen3_DIR variable, but it has no effect
# yet shows up in the TUI/GUI display as "not found".
# and due to not being marked as advanced, it can mislead people
# as the EIGEN3_INCLUDE_DIR variable which does have an effect
# is marked as advanced. Tested on Fedora28 with Eigen3-3.3.5 rpm.
