The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
Upstream changes to the build system required adjusting many packages'
dependencies. On the Nixpkgs side, we no longer propagate the dependency
on cmake (to reduce closure size), so downstream dependencies had to be
adjusted for most packages that depend on kdelibs.
The autoconf build system for poppler does not support building the
wrappers separately, so this slightly enlarges the size of closures. To
compensate, the command-line utilities have been separated into their
own package.
