* FindKDE4: Added note about KDE4_FOUND result variable (it is set by
the upstream FindKDE4Internal module, and now also synced in the docs
and code for consistency).
For the sake of completeness with other find modules, also the following
deprecated find modules are synced as they already provided these
variables:
* FindDart: Documented the Dart_FOUND result variable.
* FindUnixCommands: Updated documentation (documented UnixCommands_FOUND
result variable, and listed cache variables used by this module).
