If you don't have a Source: tag, where do you get your files from?
Out of the blue? From "what's there at that moment"?
This is against common RPM rules, even those that apply to packaging
binary software.

Right, and your "runtime tree" should be included as "source".

This depends. *Only* of that extracted tree contains, say,
/usr/lib/myproduct/... and nothing else, you can include
just /usr/lib/myproduct. But never include a system
directory (like /usr, /usr/lib, etc.) in your binary RPM,
so wildcards like /usr/* or /* should never be used.

Also against the way RPM is intended to be used.
The proper way, IMHO, is using the tar'ed binary tree as source
file.
...
Source: myproduct.tar.gz
...
%prep
# create dir before untarring
%setup -c
%build
# probably empty
%install
mkdir -p %{buildroot}
# assuming you tar has a directory tree from the root
cp -a * %{buildroot}/
%clean
rm -rf %{buildroot}
%files
%defattr(-,root,root)
# whatever is appropriate
/usr/bin/*
/usr/lib/*
The shortcut could be to not extract the source in %prep, but to
untar that manually in %install:
cd %{buildroot}
tar -xzf %{SOURCE0}
But in my experience, having packaged many third-party binary stuff,
you often want to tweak some things (maybe not needed in your case).
Have fun,
