No, you misunderstand. RPM autodetects what libraries a binary is
dependent on at the end of the build process and puts that information
into a package. The only information you need to supply is which
development packages need to be installed before the source package can be
rebuilt.

No. It doesn't work well for those who build software themselves from source
and install new versions over and over. But that's what package managers
are for. If you're not competent enough to deal with that, then you should
just use binary packages provided by other people who are.

Why would an ordinary user want to waste time compiling from the source?
That's what binary packages are for. Just download and install.

I don't understand what you wanted to say in the above example.
