Upgrade to hdf5 1.8.18

[qwhelan]

A few CVEs were reported and fixed in hdf5 back in November 2016: http://blog.talosintelligence.com/2016/11/hdf5-vulns.html

The hdf5 release notes for that release are available here: https://support.hdfgroup.org/ftp/HDF5/current18/src/hdf5-1.8.18-RELEASE.txt

For additional info, please see: conda-forge/hdf5-feedstock#68 and conda-forge/hdf5-feedstock#71

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

@qwhelan thanks for the PR! There seems to be a conflict between hdf5 and cmake, though I can't see a reason why. There don't seem to be any clashing dependencies.

It is not cmake, sometimes conda gets "confused" resolving package conflicts, the issue lies with libnetcdf and gdal. Both dependencies must be available with latest hdf5 before we re-triggerthe CIs here.

[qwhelan]

Yeah, I need to fix libnetcdf to fix gdal too. Is there a way for me to re-trigger the CIs without amending the commit?

Is there a way for me to re-trigger the CIs without amending the commit?

Closing and re-opening usually does the trick. If not just ping me and I will restart the CIs.

Thanks for another one @qwhelan!
