#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module defines the following variables:
#
# ::
#
#   LIBSUBUNIT_INCLUDE_DIRS  - where to find subunit/child.h
#   LIBSUBUNIT_LIBRARIES     - List of libraries when using libsubunit.
#   LIBSUBUNIT_FOUND         - True if subunit library found.
#
# Hints

#
# A user may set ``LIBSUBUNIT_ROOT`` to a subunit library installation root to tell this
# module where to look.
