- quote string literals.
In the hope it improves syntax-highlighting and readability.
- use lowercase, underscore-prefixed local var names.
As a hint for scope, to help readability.
- prefer `pkg_search_module` (over `pkg_check_modules`).
They are the same, but `pkg_search_module` stops searching
at the first hit.
- more `IN LISTS` in `foreach()`.
- OtherTests.cmake: clear `CMAKE_EXTRA_INCLUDE_FILES` after use.
- add `PROJECT_LABEL` for http/client and unit test targets.
- sync `Find*` module comments and formatting.
- drop a few local variables.
- drop bogus `CARES_LIBRARIES` from comment.
- unquote numeric literal.

Closes #14388
