-# GetPrerequisites.cmake
-#
-# This script provides functions to list the .dll, .dylib or .so files that an
-# executable or shared library file depends on. (Its prerequisites.)
-#
-# It uses various tools to obtain the list of required shared library files:
-# dumpbin (Windows)
-# ldd (Linux/Unix)
-# otool (Mac OSX)
-#
-# The following functions are provided by this script:
-# gp_append_unique
-# is_file_executable
-# gp_item_default_embedded_path
-# (projects can override with gp_item_default_embedded_path_override)
-# gp_resolve_item
-# (projects can override with gp_resolve_item_override)
-# gp_resolved_file_type
-# gp_file_type
-# get_prerequisites
-# list_prerequisites
-# list_prerequisites_by_glob
-#
-# Requires CMake 2.6 or greater because it uses function, break, return and
-# PARENT_SCOPE.
