Packaging cquery

Packaging cquery

[brettg]

Hi all, I am attempting to package cquery.

Here is my definition

(define-public cquery
   (package
    (name "cquery")
    (version "20180718")
    (source (origin
	    (method url-fetch)
	    (uri (string-append 
"https://github.com/cquery-project/cquery/archive/v"
				version ".tar.gz"))
	    (sha256
	     (base32
	      "076cavgipn6g37fhvdcq0z915c5lxxa56mbxw9d6njksdxg1wdkj"))))
    (build-system cmake-build-system)
    (inputs
     `(("python" ,python-wrapper)
       ("clang" ,clang)))
    (home-page "https://github.com/cquery-project/cquery")
    (synopsis "C/C++ language server supporting multi-million line code 
base, powered by libclang")
    (description "Add later.")
    (license license:x11-style)))

the configuration seems to fail when cmake attempts to download clang. 
Does anybody know how to get it to ignore this request and use the 
system clang (which I assume is the correct (guix) way to do this.

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. :)

'guix lint cquery' will remind you to use git-fetch =).

Checking the source, I suspect you'll find the answer here:
https://github.com/cquery-project/cquery/blob/v20180718/CMakeLists.txt#L11

It looks like we have at least some of the third party libraries already
packaged but I'm not sure how the unbundling process is going to be. I'd
suggest starting with it as-is and working one those later.
