Subject: [PATCH] Correct append of -std to CXX flags

The previous approach, in the presence of existing CXX flags, resulted
in a broken CMAKE_CXX_FLAGS value with a `;` in the middle. The
canonical way of adding a compile option is to use the cmake function
`add_compile_options`, which is available from 2.8.12 onwards.

If you need something compatible with cmake 2.8.11 and prior, you can
use `add_definitions(-std=c++0x)` instead.
