Add WITH_ITK in CI

[kerautret]

PR Description

Activate WITH_ITK options in GitHub Actions and fix an ITK 4 versus 5.0 function call.
It works in linux distribution but a #include<cmath.h> makes some strange errors, after numerous tries I am giving up.. Perhaps trying again later after update of Xcode.

It looks good to me. The latest major version of ITK is 5, and here you are using libinsighttoolkit4-dev but I don't expect it changes much.

Thanks, yes it was more easy to use the version 4 since I do not see any package yet (and it could be quite long to include from sources in CI)
