# - Find PUPIL
# Find the native PUPIL libraries
# NOTE: the Java link library is required to link with PUPIL, so this module will find it as well
#
# This module defines the following variables:
#
#  PUPIL_LIBRARIES, the libraries needed to use PUPIL.
#  PUPIL_FOUND, If false, do not try to use PUPIL.
#
# If pupil was found, this module also creates the following imported target:
#  pupil::pupil - Target for pupil library
