# FindPCRE
# --------
# Finds the PCRECPP library
#
# This will define the following variables::
#
# PCRE_FOUND - system has libpcrecpp
# PCRE_INCLUDE_DIRS - the libpcrecpp include directory
# PCRE_LIBRARIES - the libpcrecpp libraries
# PCRE_DEFINITIONS - the libpcrecpp definitions
#
# and the following imported targets::
#
#   PCRE::PCRECPP - The PCRECPP library
#   PCRE::PCRE    - The PCRE library
