# @brief           Define an Impeller component. Components are different
#                  Impeller subsystems part of the umbrella framework.
#
# @param[optional] target_type  The type of the component. This can be any of
#                               the target types supported by GN. Defaults to
#                               source_set. If Impeller is not supported on the
#                               target platform, this target is a no-op.
