Summary:                    Double backslash to escape '#' in CMAKE_CXX_FLAGS no
longer works
Description: 
In versions of CMake prior to 3.1.0, this worked:

  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-\\#pragma-messages")

In CMake 3.1.0, that no longer works; this, however, does:

  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-#pragma-messages")

I'm not sure if this is a deliberate change or not; but it's a slightly annoying
break with backward compatibility.
