LGTM after fixes (no need to re-review with me).

Please, update and proceed with the next reviewer.

Please, reflect comments to the first patch here: the library naming,
motivation of the change, the issue number.

Nit: I suggest to refer include directory as
"${PREFIX}/include/tarantool" -- it makes quite clear that it may be
/usr/include/tarantool, /usr/local/include/tarantool or something of
this kind.

AFAIR, just %{_includedir}/tarantool/curl (without %dir) should work
well and should install the whole directory. It'll allow us to update
libcurl beyond 7.73.0 (see [1]) without a fear to forget to update those
rules.

There is a risk to miss a problem with installing the headers (if cmake
does not install it because of some problem), however partial installing
looks even worse.

How about Debian based distributions? Nothing to change, the headers
will be installed?
