FindPerlLibs
------------
Finds Perl libraries. Perl is a general-purpose, interpreted, dynamic
programming language. This module detects whether Perl is installed and
determines the locations of include paths, libraries, and the library name.
Result Variables
^^^^^^^^^^^^^^^^
This module sets the following variables:
``PerlLibs_FOUND``
True if ``perl.h`` and ``libperl`` were found. For backward compatibility,
the ``PERLLIBS_FOUND`` variable is also set to the same value.
``PERL_SITESEARCH``
Path to the sitesearch install directory (``-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.
Cache Variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``PERL_INCLUDE_PATH``
Directory containing ``perl.h`` and other Perl header files.
``PERL_LIBRARY``
Path to the ``libperl``.
``PERL_EXECUTABLE``
Full path to the ``perl`` executable.
Examples
^^^^^^^^
Finding Perl libraries and specifying the minimum required version:
.. code-block:: cmake
find_package(PerlLibs 6.0)
#]=======================================================================]
# find the perl executable
include(${CMAKE_CURRENT_LIST_DIR}/FindPerl.cmake)

execute_process(COMMAND "${PERL_EXECUTABLE}" -V:${tag}
OUTPUT_VARIABLE result
RESULT_VARIABLE status)
if (NOT status)
string(REGEX REPLACE "${tag}='([^']*)'.*" "\\1" result "${result}")
if (_PGI_IS_PATH)
file(TO_CMAKE_PATH "${result}" result)
endif()
