FindPerlLibs

查找 Perl 库

该模块查找是否安装了 PERL，并确定 include 文件和库的位置。它还会确定库的名称。此代码设置以下变量

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

可以使用标准语法指定所需的最低 Perl 版本，例如 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 (-V:installsitesearch)
PERL_SITEARCH       = path to the sitelib install directory (-V:installsitearch)
PERL_SITELIB        = path to the sitelib install directory (-V:installsitelib)
PERL_VENDORARCH     = path to the vendor arch install directory (-V:installvendorarch)
PERL_VENDORLIB      = path to the vendor lib install directory (-V:installvendorlib)
PERL_ARCHLIB        = path to the core arch lib install directory (-V:archlib)
PERL_PRIVLIB        = path to the core priv lib install directory (-V:privlib)
PERL_UPDATE_ARCHLIB = path to the update arch lib install directory (-V:installarchlib)
PERL_UPDATE_PRIVLIB = path to the update priv lib install directory (-V:installprivlib)
PERL_EXTRA_C_FLAGS = Compilation flags used to build perl
