   1 # - Find Perl libraries
   2 # This module finds if PERL is installed and determines where the include files
   3 # and libraries are. It also determines what the name of the library is. This
   4 # code sets the following variables:
   5 #
   6 #  PERLLIBS_FOUND    = True if perl.h & libperl were found
   7 #  PERL_INCLUDE_PATH = path to where perl.h is found
   8 #  PERL_LIBRARY      = path to libperl
   9 #  PERL_EXECUTABLE   = full path to the perl binary
  10 #
  11 # The minimum required version of Perl can be specified using the
  12 # standard syntax, e.g. find_package(PerlLibs 6.0)
  13 #
  14 #  The following variables are also available if needed
  15 #  (introduced after CMake 2.6.4)
  16 #
  17 #  PERL_SITESEARCH    = path to the sitesearch install dir
  18 #  PERL_SITELIB       = path to the sitelib install directory
  19 #  PERL_VENDORARCH    = path to the vendor arch install directory
  20 #  PERL_VENDORLIB     = path to the vendor lib install directory
  21 #  PERL_ARCHLIB       = path to the arch lib install directory
  22 #  PERL_PRIVLIB       = path to the priv lib install directory
  23 #  PERL_EXTRA_C_FLAGS = Compilation flags used to build perl
