[eigen] Upgrading to cmake 3.5 or 3.0?

[Christoph Hertzberg <chtz@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hi!

Recently, this bug/request was added, asking to raise the required cmake 
version to 3.5.1:
https://eigen.tuxfamily.org/bz/show_bug.cgi?id=1767

This should only concern you if you have a rather old Linux distribution 
AND you want to install an up-to-date Eigen-version (which would still 
be possible by manually copying the relevant headers) or build the 
test-suite/documentation on your machine.

Since barely anyone follows every bug report, I'm asking on this mailing 
list, if there are (reasonable) objections against that step?
If not, we'd upgrade our minimal version with the Eigen-3.4 release (and 
perhaps for Eigen-3.3.8 release as well).

Preferably, do technical discussions at the bug-entry (if you don't have 
an account, and only small, non-technical comments, of course just 
answering here is fine).


Cheers,
Christoph
