Title: CMake will fail with an error when enabled packages can't be found

Most packages have been set to required which should cause CMake to fail with an error if that package has been enabled but can't be found. Other packages which don't use a find module have also been changed to this behaviour.

Also error() which isn't a cmake command has been replaced with message(FATAL_ERROR).
