Summary0007898: Improved FindPerl.cmake
DescriptionI've written a better FindPerlLibs.cmake module some time ago. I've polished it and here is the latest version. It uses the perl executable to determine each needed variable.
Additional InformationThis is the output of my CMakeLists.txt. Note: perl 5.10.0 has no libperl.so

 You're right. Updated file uploaded.

 Are you sure there's no libperl?

On Fedora Core 9 it's moved:
/usr/lib/perl5/5.10.0/i386-linux-thread-multi/CORE/libperl.so

Also on macports (5.8 I know, but there's a pattern showing):
/opt/local/lib/perl5/5.8.8/darwin-thread-multi-2level/CORE/libperl.dylib

I suggest adding $Config{installarchlib}/CORE to the library search path.

Cheers,
Rob

 The dynamic search for this patch looked like a good thing to merge. I was put off by the discussion regarding whether perl 5.10 has libperl.so or not. Did this ever get resolved? It would be nice to merge something that works across all perl versions. Rhaines' suggestion looked promising.

 Yes, this was fixed. I've uploaded a new version of the file.

There was a time problem on the server an my reply got posted before the first comment.

This is the fixed file.

 Thanks for the patch. I checked it in with some minor changes.

* added PERL_ARCHLIB/CORE to library & include search paths, so it would find the libraries on my system (also should help with macports and other systems where perl isn't in /usr/lib/perl5)
* merged some minor things from the existing FindPerlLibs.cmake into it (e.g. calling include(FindPerl) to find perl executable & FindPackageHandleStandardArgs)
* made search for include directory & library conditional on having PERL_EXECUTABLE
* mark_as_advanced() isn't needed for non-cache variables.
