Summary:                    PRIVATE linking with target_link_libraries
propagates "usage requirements" for static libraries
Description: 
I have projects in the structure shown below

    module (EXECUTABLE)
       |
       \-- submodule (STATIC_LIBRARY)
               |
               \-- subsubmodule (STATIC_LIBRARY)

'submodule' links with 'subsubmodule' using PRIVATE linking as below

   target_link_libraries(submodule PRIVATE subsubmodule)

'module' links with 'submodule'. It is expected that the 'module' does not get
the public include directories of 'subsubmod'. However we see this happening in
cmake 2.8.12.

It is understood that the libraries linked with 'subsubmodule' are propagated to
'module' since 'subsubmodule' and 'submodule' are STATIC libraries. However this
does not apply to the INCLUDE directories and COMPILE definitions.

We also note that for SHARED libraries, the PRIVATE linking works fine.
