FYI I am fine with having Shambhala have as many tests as we want, but in general we should have the Drake self-tests catch things like this pre-merge to the extent practical.

[EricCousineau-TRI]

Sounds good!

It'd still be nice, though, if all unittests were run on CI (e.g. ensuring that GTest is always found on CI, which may have not been the case?)
See #86 #87

Updated since RobotLocomotion/drake#7809 is fixed.

This functionality does exist in CMake, so not an actionable TODO unless you want us to add the functionality and move to a newer CMake (which I doubt you do just for this).

Do we need all these imports?

Sorry, I meant to add double quotes.
