MacOS build script & Github Action for Trelis 17.1 and Cubit 2020.2

[bam241]

This builds on top of #84 , review after merge.
This also relies on svalinn/mcnp2cad#73

This includes:

• build script to build the plugin on MacOS
• GItHub Action to build the plugin on MacOS for Trelis17.1 and Cubit 2020.2

[bam241]

this needs to be changed when svalinn/mcnp2cad#73, gets merged.

this works [email protected] added a new PR depedency: svalinn/DAGMC#728

we could avoid svalinn/DAGMC#728 and limit hdf5 version to 1.10.7

[bam241]

getting the following error when trying to load Cubit2020.2 plugin built with the GitHub action:

ERROR: <stdin>, line 0. Error loading /Applications/Coreform-Cubit-2020.2.app/Contents/MacOS/plugins/libsvalinn_plugin.so:
ERROR: <stdin>, line 0. 
Finished Command: undo on

installing brew install eigen hdf5 using brew solves it.

I guess we have to ship some of those within the package

[bam241]

it was actually slightly more complicated than that:
one of the hdf5 deps was required not hdf5 itself brew install szip

[bam241]

I fixed it adding /libsz.2.dylib in the plugin and running :
sudo install_name_tool -change /usr/local/opt/szip/lib/libsz.2.dylib @rpath//libsz.2.dylib libsvalinn_plugin.so

[bam241]

inclusion of szlib fixed it.

I plan to review this after we merge #84 to focus on the Mac parts...

[gonuke]

Given my contribution, I probably shouldn't merge this.... but I approve

[gonuke]

I think this is ready to go @pshriwise

[bam241]

as a reminder this depends on svalinn/mcnp2cad#73

[bam241]

@pshriwise when you have time could you take a look here ?

[pshriwise]

Overall this looks pretty good to me. There are just some outstanding issues that @gonuke raised I think:

• looking into merging the Linux and Mac workflow files
• getting diff's of the Cubit CMake files from the SDK and look into patching those instead of including the modified files

Also if we can communicate the changes we needed to make to the CMake files Coreform that would probably be good.

Thanks @bam241! On to the next PR I suppose 😃
