# Locate miniupnp library

#  MINIUPNP_LIBRARY, the miniupnp variant
#  MINIUPNP_INCLUDE_DIR, where to find miniupnpc.h and family)
#  MINIUPNPC_VERSION_PRE1_6 --> set if we detect the version of miniupnpc is
#                               pre 1.6
#  MINIUPNPC_VERSION_PRE1_5 --> set if we detect the version of miniupnpc is
#                               pre 1.5
#
# Note that the expected include convention is
#  #include "miniupnpc.h"
# and not
#  #include <miniupnpc/miniupnpc.h>
# This is because, the miniupnpc location is not standardized and may exist
# in locations other than miniupnpc/
