# FindCheck
# ---------------
#
# Find the "Check" C unit testing framework.
#
# See https://libcheck.github.io
#
# The Debian package for this is called ``check``
#
# Targets
# ^^^^^^^
#
# If successful, the following imported targets are created.
#
# ``libcheck::check``
#
# Cache variables
# ^^^^^^^^^^^^^^^
#
# The following cache variable may also be set to assist/control the operation of this module:
#
# ``LIBCHECK_ROOT_DIR``
# The root to search for libcheck.
