# - Try to find the PCRE regular expression library
# Once done this will define

# PCRE_FOUND - system has the PCRE library
# PCRE_INCLUDE_DIR - the PCRE include directory
# PCRE_LIBRARIES - The libraries needed to use PCRE
# under Windows this also checks in the GNUWIN32 directory, so make
# sure that the GNUWIN32 directory gets found if you use the GNUWIN32 version of PCRE
#
# under windows, try to find the base gnuwin32 directory, do nothing under UNIX
