Comment 1 Mamoru TASAKA 2021-01-18 14:23:10 UTC 
Oops... actually this report is against eigen3, but blender fails to build due to the same reason...
Comment 2 Nicolas Chauvet (kwizart) 2021-01-18 20:05:06 UTC 
Thanks for the report.

Seems like blender have a technical debt with respect to unbundling...
Once blender uses a fixed system version, it will be fine.
