Description
A long time ago, our LGTM Check used to work with the C/C++ code, but it stopped doing so. Currently, this is because it runs setup.py using Python 2 and we have Python 3.6 syntax in it. We should be able to configure it to not use Python 2 easily.
However, prior to that, it failed because it could not download jQuery. I am working towards removing that requirement entirely, but this is something we should keep in mind if more things are downloaded (e.g., #16720).
And before anyone asks about the utility of LGTM, yes it's not blocking and full of many false positives, but I did go through it once and find several real bugs (e.g., #16802.) And since C/C++ is probably the language with least proficiency on the team, more eyes on it would be better.
