Summary:                    cmDependsC class Scan ignore same file name
Description: 
cmDependsC use cache for speed up dependences scan. But produce a bug.
When you have two or more file with same name in different directories.
cmDependsC will miss some of file.

Steps to Reproduce: 
create src tree like this.
xxx/
   t.h
   a.h
   src/
      a.h
      a.cpp
a.cpp include ../t.h && a.h
t.h include a.h
create a CMakeLists.txt "add_executable(a a.cpp)"
then in xxx do
$ mkdir build && cd build && cmake ../src && make
$ cat CMakeFiles/a.dir/depend.internal

we get result like:
CMakeFiles/a.dir/a.cpp.o
 /home/jcz/Desktop/src/test/cmake/samefilename/src/../t.h
 /home/jcz/Desktop/src/test/cmake/samefilename/src/a.cpp
 /home/jcz/Desktop/src/test/cmake/samefilename/src/a.h

no ../a.h
