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 (-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)
|
