Summary:                    Dependency check mechanism ignores deleted header
files
Description: 
On Fedora 18, CMake 2.8.10.2, using the default "Unix Makefile" generator, CMake
improperly detects the removal (or update) of a C++ header file when it has been
manipulated (see below steps to reproduce).

This leads to CMake wrongly believing the project is up-to-date, when it fact
some source files have been modified.

Steps to Reproduce: 
The attached archive provides two files:
  simple.cxx, which includes: 
  simple.hxx (no functional content)

Untar the attached archive. Go to the directory. Then execute:

> mkdir BUILD && cd BUILD
> cmake .. && make
> mv ../src/simple.hxx ../src/simple.OLD
> make
  ----> ERROR (as expected)
> mv ../src/simple.OLD ../src/simple.hxx
> make
  ----> OK! (as expected)
> mv ../src/simple.hxx ../src/simple.OLD
  ----> No dependency scanning, no update, no reconstruction!! The build
(wrongly) succeeds.
