 - if you only want to override the source information, you do not need
to redefine the package in spacebot's autobuild files. Simply add the
updated source information in the overrides: section of source.yml
 - if you do want to change how the package is configured, you should
use setup_package

setup_package 'package_name' do |pkg|
  # Do stuff here
end

This will allow you to modify the original configuration. You should
redefine the package using cmake_package, ... only if you want to
completely replace the configuration.
