Summary: Error when one of the parent directory is a symlink
to it's parent directory
Description:
If one of the parent directory of the source directory is a symlink to one of
its parent directory, cmake fails at configure time on add_subdirectory.
Directory structure to reproduce this:
```
% tree
.
├── 1
│ ├── 2
│ │ └── cmake
│ │ ├── a
│ │ │ └── CMakeLists.txt
│ │ └── CMakeLists.txt
│ └── 4 -> .
└── 3 -> 1
6 directories, 2 files
```
The higher level `CMakeLists.txt` is
```
% cat 1/2/cmake/CMakeLists.txt
project(cmake-test)
cmake_minimum_required(VERSION 2.8)
add_subdirectory(a)
```
and the lower level `CMakeLists.txt` is empty.
When trying to build in `1/4/2/cmake/build`
```
% cmake ..

CMake Error at CMakeLists.txt:3 (add_subdirectory):
add_subdirectory not given a binary directory but the given source
directory "/home/yuyichao/tmp/cmake-test/1/4/4/4/2/cmake/a" is not a
subdirectory of "/home/yuyichao/tmp/cmake-test/1/4/4/2/cmake". When
specifying an out-of-tree source a binary directory must be explicitly
specified.
-- Configuring incomplete, errors occurred!
