boost 也使用 c++11 编译的话，　librime 链接出错 #586

系统的　boost 如果使用　c++11 编译安装的话，　librime 
会在最后链接的时候出错。
错误提示为

../lib/librime.so.1.1.0：对‘boost::filesystem::detail::copy_file(boost::file
system::path const&, boost::filesystem::path const&, 
boost::filesystem::copy_option::enum_type, 
boost::system::error_code*)’未定义的引用。

如果　boost 使用　c++98　模式编译的就没问题。

gcc-4.8.2
binutils-2.24
boost-1.55

找到原因了，　是　librime 使用了　BOOST_NO_SCOPED_ENUMS 
这个是在　boost 本身是　c++98 模式编译，而　librime 
使用　c++11 编译才需要使用的一个　workarround 。

可以在　cmake 里检测一下 boost 是否是在　c++11 
模式下编译的，是的话再启用那个。

Which version of librime?

BOOST_NO_SCOPED_ENUMS is deprecated.

My code at master has
#define BOOST_NO_CXX11_SCOPED_ENUMS

Try this fix:
https://github.com/lotem/librime/commit/c705ccb0fea88747c080d14ae6c26268639b9762

Just pass -DBOOST_USE_CXX11=ON to cmake in the command line.
