When CMake 2.4 generates the build tree for CMake itself it asks the built CMake to install itself using the rules that 2.4 generated. Since the install rules use undocumented commands that are not compatible from 2.4 to 2.6 we need a special case to avoid failure. This sets a special indicator variable in the install rules that enables a compatibility hack to support the old install rule format.
