I recently downloaded Eigen 3.4.0. I have added it locally to the project I created. However, I am getting the red squiggly lines with the drag-over error - namespace "Eigen" has no member "VectorXd".
I tried adding the path of Eigen to c_cpp_properties.json, settings.json as well as tasks.json to no avail. I was expecting to get the auto-complete suggestions but to no avail.
c_cpp_properties.json

EDIT: The code compiles and runs absolutely fine through the terminal. The problem is purely with getting the auto-suggestions.
EDIT 2: The answer which was suggested does not answer my question. I have already added the path to includePath and <Eigen/Dense> is recognised. However, intelliSense does not give auto-suggestions for Eigen. My problem is specific to Eigen.
