[Development] Android missing SONAME in lib's causes issues with cmake

[Charles Yin]

CMake automatically adds rpaths to all targets, which you are linking with
target_link_libraries().

To switch it off there is CMAKE_SKIP_RPATH option.

See http://www.cmake.org/Wiki/CMake_RPATH_handling for more details.
