The other way is to work backwards by looking at the install dependencies
that rpmbuild discovered, or the NEEDED lines from objdump -x, and adding the
-devel versions of those libraries. That won't catch any compile-time-only
dependencies, though (like libtool, autoconf or flex) but it will give you
something to start from.  Note also that some programs will automatically
discover what optional libraries are available at build time and configure
themselves accordingly. So, if you miss some BuildRequires, you might end up
with a binary that works but is missing features.
