# Xcode throws an error if an iOS target depends on a Mac OS X target. So
# any place a utility program needs to be build and run, an action is
# used to run ninja as script to work around this.
# Example:
# {
#   'target_name': 'foo',
#   'type': 'none',
#   'variables': {
#     # The name of a directory used for ninja. This cannot be shared with
#     # another mac build.
#     'ninja_output_dir': 'ninja-foo',
#     # The full path to the location in which the ninja executable should be
#     # placed. This cannot be shared with another mac build.
#    'ninja_product_dir':
