Yeah IMO it’s a good idea to reuse ‘home-page’ like this patch does.

So, first things first.  The priority should be to run tests and remove
the bundled googletest, which I tried with the patch below.

Now, tests won’t run because apparently they try to use ‘sudo’ (!):

Could you check whether they can run at all without root privileges, and
if not, document it in a comment above #:tests? #f?

Thanks,

unfortunately, tests are executed virtualized with lxc/lxd, while
technically it seems to be possible to execute them, but it will 
require
fixing (but probably rewriting) python test runner code. Possible 
but
not feasible i think.

On the other hand, as far as it is mentioned in their release 
process,
sources release tarball is releaced after tests passing.

;; tests are virtualized with lxc/lxd, it is not very feasible
;; to make them executable under guix build

Will this commend do the work?
