Fixed BUILD_SHARED_LIBS meaning.

Browse Source 
There are three switches to build static/shared libraries.

Here is the logic.

If BUILD_SHARED_LIBS is defined
   If BUILD_SHARED_LIBS is ON
      build only shared-library
   Else
      build only static-library
   Endif
Else
   If MSGPACK_ENABLE_SHARED is ON (default)
      build shared-library
   Endif
   If MSGPACK_ENABLE_STATIC is ON (default)
      build static-library
   Endif
Endif

Here is common settings:

If you want to build both static/shared libraries, don't set switches.
If you want to build only shared-library, set BUILD_SHARED_LIBS=ON.
If you want to build only static-library, set BUILD_SHARED_LIBS=OFF.
