# - Find Perl libraries
# This module finds if PERL is installed and determines where the include files
# and libraries are. It also determines what the name of the library is. This
# code sets the following variables:
#
#  PERL_INCLUDE_PATH = path to where perl.h is found
#  PERL_EXECUTABLE   = full path to the perl binary
#
