CMakeList: add option to not install NuGet packaging

[yann-morin-1998]

The NuGet hiredis.target packaging description file is of no use on systems that are not using NuGet, like Linux systems, and the spurious presence of that file is not "clean".

Add a cmake option to allow users to disable installation of that file. As some people may have relied on that file to be installed, continue to install it by default.

@michael-grunder Hi Michael!

Thanks for triggerring the workflows. I've looked at the failures, but
I'm not sure they are related to this change:

• macOS workflow: the failure happens in the job setup, while
  downloading the dependencies;

• BSD workflow: it looks like the test system in the VM is constantly
  reoobting (or retarting) even before starting the build, and the VM
  was killed after 6 hours.

Let me know if I can do something to help solve those two.

@michael-grunder Hey Michael,

The macos workflow still fails, because the [email protected] formula does not exist in brew;
I could only spot @7.2 (7.2.4) and @6.2 (6.2.14): https://formulae.brew.sh/formula/redis

Yep,the failure is unrelated to yoru PR. I will fix CI and then get this merged.

OK CI is fixed on the master branch. If you rebase against that the tests should now pass here as well.

One other question however. I understand the impulse ot not change behavior but is there any reasonable reason that Linux systems would have come to rely on this NuGet build artifact?

There is always the possibility of reasons like this but I think maybe we can just consider it a bug and not install the file by default?

Thing is, cmake is not necessarily Linux-only. I haven't touched a Windows machine
in more than 20 years now, so I have absolutely no idea what is going on on that side
of the universe, but it is my understanding that cmake works on Windows, so maybe some
people are using the cmake on Windows to build NuGet packages there...

I am totally fine with making the changing the default to OFF, if you prefer. Just tell me,
Ill do that then repush.

Thanks!

I'm in the exact same boat. Literally clueless about the Windows side of things.

I did a quick bit of reading and apparently NuGet does have some cross-platform support via .NET core so I think the safest solution is to use your change as-is. I can circle back to this in the future to flip the default to OFF if it ever comes up again.

Happy to merge once the branch is rebased.

Thanks!

Merged, thanks!
