WIP easyconfig pushed to https://github.com/vscentrum/vsc-software-stack/tree/wip/481_OpenFOAM6

It basically works, but only when excluding ParaView as dependency (which should be OK, impact of that is basically that paraFoam utility won't be available).

There's a problem with the patch being used though, it assumes that ParaView is included as dependency since it relies on $EBROOTPARAVIEW, which leads to a failure in the sanity check:

== 2025-01-06 16:41:29,127 build_log.py:171 ERROR EasyBuild crashed with an error (at easybuild/easybuild-framework/easybuild/base/exceptions.py:126 in __init__): Sanity check faii

So we'll need to create a custom patch that doesn't assume that ParaView is available, or includes some kind of fallback mechanism in case $EBROOTPARAVIEW is not defined.
