Automatic download and build of MOAB

[bam241]

Description

Add capability to automate pull and build MOAB at DAGMC building time

This is redondant with #964

Motivation and Context

This is part of the project from @shimwell on getting a pip install for OpenMC with DAGMC.

Changes

tweaked a little bit the findMOAB.cmake

• add a make files that contains the proper ExternalProject configuration
• add a CMAKE variable to enable pull and build and change the dips and link for the other DAGMC library

Behavior

Nothing changes if DDL_DEPS is not set at ON on Cmake configuration.
Otherwise pull build MOAB from MOAB repo builds it, and build the DAGMC lib against it.

Changelog file

• Done

This is very much inspired by @ahnaf-tahmid-chowdhury work on PyNE cmake.

@ahnaf-tahmid-chowdhury @shimwell @gonuke even if this is still a draft, feel free to provide any feed back!

[bam241]

This should still return a fatal_error if ExternalProject encounters an issue

[bam241]

The safeguard I added should be improve... (i.e.: have them only MOAB download is triggered...)

[bam241]

@gonuke this still needs some polishing here and there, but I think this is ready for a first opinion.

[ahnaf-tahmid-chowdhury]

Thank you very much for the update. I have a few comments for improvement.

[ahnaf-tahmid-chowdhury]

This method may work here for now, but may create trouble while working with scikit-build-core depended project. However, I am not sure here.

[bam241]

I have no experience about scikit-build-core, maybe we shall fix it, if the problem occurs ?

[shimwell]

I believe MOAB master branch now has scikit-build core while version 5.5.1 does not.

Perhaps changing the moab version to master would provide a quick way of checking if this continues to work

[bam241]

Trying it now.

[ahnaf-tahmid-chowdhury]

What is the use of it?

[ahnaf-tahmid-chowdhury]

This is like Enable Download MOAB or Double Down?

[bam241]

this only enables MOAB Download, otherwise everything work as it used to.

[bam241]

I don't have a strong opinion about the name of the variable,
but eventually one might want to include Embree and DD the same way...

if your question is about the addition into the matrix, I needed it to allow the CI to test for this kind of build...

[bam241]

this seems to pass, I'll revert the change

[jon-proximafusion]

Testing locally with this docker file and it compiles for me
Note this points to Bam's fork and this PR branch
Also note, this example is very minimal with no DD, Embree, Pyne
