# FindPerlLibs
# ------------
#
# 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:
#
# ::
#
#   PERLLIBS_FOUND    = True if perl.h & libperl were found
#   PERL_INCLUDE_PATH = path to where perl.h is found
#   PERL_LIBRARY      = path to libperl
#   PERL_EXECUTABLE   = full path to the perl binary
#
#
#
# The minimum required version of Perl can be specified using the
# standard syntax, e.g.  find_package(PerlLibs 6.0)
#
# ::
#
#   The following variables are also available if needed
#   (introduced after CMake 2.6.4)
#
#
#
# ::
#
#   PERL_SITESEARCH    = path to the sitesearch install dir
#   PERL_SITELIB       = path to the sitelib install directory
#   PERL_VENDORARCH    = path to the vendor arch install directory
#   PERL_VENDORLIB     = path to the vendor lib install directory
#   PERL_ARCHLIB       = path to the arch lib install directory
#   PERL_PRIVLIB       = path to the priv lib install directory
#   PERL_EXTRA_C_FLAGS = Compilation flags used to build perl
