homebrew build is broken

[osrf-migration]

Original report (archived issue) by Steve Peters (Bitbucket: Steven Peters, GitHub: scpeters).

---

Since the ign-cmake branch was merged in pull request #51, several CI builds have been broken, including homebrew. I just added a homebrew formula for ignition-cmake1 and updated the ignition-rendering formula to a more recent commit and to use the newer version.

• osrf/homebrew-simulation@87fcc84
• osrf/homebrew-simulation@4591cca

It's still failing though: https://build.osrfoundation.org/job/ignition_sensors-ci-default-homebrew-amd64/12/

a little more context after reproducing locally with --verbose:

seems like a problem with FindOptiX? cc @mxgrey

My best guess at the moment is that maybe the optix_rpath variable is blank, causing cmake to have an error.
