grid_map_filters package fails during build

[Kukhokuhle]

Hi all,

I am on Ubuntu 20.04 and using ROS noetic.

Attempting to build grid_map is unsuccessful because the grid_map_filters package fails. I get the idea that the issue is with Eigen and opencv2 but I am unable to pin it down.

Here is the output of the build process:

I have tried in 20.04 and 18.04, 20.04 can build succeed without any other operations. create a new virtual env and retry?
