Install on Mac

[SiccarPoint]

Hi Richard,

Moving this over here as I suspect it might be related to r-barnes/Barnes2020-FillSpillMerge#2.

Decided to try direct installs of richdem (on pip, fine) and dephier, and for dephier this happened. The build appears to get made OK, but then I cannot actually run the software, with the prompt complaining dyld: Library not loaded: @rpath/libomp.dylib... Reason: image not found. Note that the upgrade command also appears not to have taken here. Possibly this is also happening with r-barnes/Barnes2020-FillSpillMerge#2.

Again, same setup as at the other issue: iMac Catalina, forced downgrade of the Xcode SDK to 10.9 to get cmake firing.

I resolved the submodule update; I needed git submodule update --recursive not git submodule --update --recursive as in the readme.

But even with this fixed, I still cannot run dephier.exe, with everything looking exactly as above.

[SiccarPoint]

I made #6 to separate these issues out, for convenience.

@SiccarPoint : The issue you're finding is something to do with your environment. This suggests that you try:

brew install libomp

This has fixed it! Thank you!
