Warnings treated as errors

[peterpanning]

Hi--can't compile this OOTB by following instructions here and on the associated video because warnings generated from format.h are treated as exceptions. You can work around this by not treating warnings as exceptions in the CMakeLists file. Would you mind?

EDIT: This doesn't necessarily seem to be related exactly to the zerocheck issue I thought might be causing it, but I still cannot compile this OOTB.

@peterpanning I am able to build the current master branch just fine. I think without a full build log (and source code) it will be hard to judge where something went wrong.

To be sure that this is still the case in the future, I opened a PR that will add a CI build to check for build errors in the current repository: #6
