commit e702abfd16f610e773fb0310d8c6512991794c63
Author: Yury G. Kudryashov [diff odt] <urkud.urkud@gmail.com>
Date: Wed Mar 21 00:50:02 2012 +0400
Rewrite FindPerlMore.cmake
* Ask perl for expanded paths
* Move execute_process to a macro
* Add PERL_*_INSTALL_DIR variables that point to CMAKE_INSTALL_PREFIX
The last change makes it easy to install a file into CMAKE_INSTALL_PREFIX
instead of perl install prefix.Add debug message
