These two commits are required for the port to build with CMake 3.0.
See patch-CMakeLists.txt as well.

A) fixed new CMAKE policy CMP0045 issue in CMakeLists.txt. This feature was introduced recently in this commit: https://gitorious.org/cmake/cmake/commit/73e93400e2efab2096618ff58a5ad68236cd04aa ... Bb) fixed CMAKE problem with cmake/CEGUIMacros.cmake when including the project with ExternalProject_Add() CMAKE feature in a project. I had to escape the '[' and ']' characters because in this way CMAKE was not recognizing those characters. CMAKE version: 2.8.12.

FIX: switch to 'if test' syntax from 'if [' for shell commands (cmake issues)
