Add version number in header files

[marcalff]

Fixes #458

Changes

• Add version numbers in header files, that can be used at compile time
• Add functions to get the library version numbers, that can be used at runtime. This helps with shared libraries.

Thanks, this is appreciated!

The PR looks good, but there is one extra thing, though: add corresponding entries for the new files in the tbump file.

Interesting tool, will look into this.

Thanks! I've added some tests; let's wait for the pipelines to turn green.

CI is a carnage, not sure why in most cases.

Found this for find_package()

/home/runner/work/rapidyaml/rapidyaml/prefix/find_package/linux-Debug/include/c4/yml/yml.hpp:4:10: fatal error: c4/yml/version.hpp: No such file or directory

Is there a place to update for new headers to install ?

May need this:

Indeed, that's missing.

Btw, the sea of red is unrelated; it's happening because GitHub updated nodejs in the workflow actions and the ubuntu18 runner is therefore no longer supported. Let's ignore this problem. Let's focus on the workflows related to install.

That is fine, I noticed all the CI cleanup required as pre requisite.

I take it this PR is to be merged after #461 is done ?

Well, by coincidence, not by necessity.

I've looked through the pipelines, and the relevant ones are all green (the install/release pipelines succeed, and the sample pipelines succeed for the relevant tests, failing later only because of an unrelated problem which happens with PRs of non-owners). So I'm merging now.

Thanks for your PR, and for sticking through this.
