Re: Packaging cquery

[jiaming yuan]

Hi Brett,

I have a working cquery and ccls package depends on clang-7:

https://github.com/trivialfis/guixpkgs/blob/b64f6fd3f8d4e04c6752e20bb7769e1c426f6ad4/code.scm#L114

I can't upstream it because there are too many bundled dependencies.  Feel free
to look into it. :)
