Can I install c-ares 1.18.1 on Ubuntu 21.10

Question

I have a problem with a program that uses c-ares and I've been told to update my c-ares to version 1.18.1.

I ran apt list libc-ares-dev and the output was

Listing... Done
libc-ares-dev/impish,now 1.17.1-1ubuntu1 amd64 [installed]
libc-ares-dev/impish 1.17.1-1ubuntu1 i386

Is there a way of installing 1.18.1 on Ubuntu 21.10? If I download the source code and do a manual install will it overwrite the package I currently have installed? Or will it install to some other location? I'm guessing there is no package available for 1.18.1?

What is "a program"? Can you lower its dependency requirements? Only 22.04 LTS will have 1.18. — N0rbert, Jan 03 '22 at 20:08
@N0rbert The program is an app I'm developing. It has an error and hence I was told to update. When will 22.04 be available? — James Read, Jan 03 '22 at 20:14

You can install this libc-ares-dev (1.18.1-1) library manually on Ubuntu 21.10 using packages from upcoming 22.04 LTS, by commands shown below:
