Summary:                    CXX_STANDARD does not support C++03 and C++14
Description: 
CXX_STANDARD support only '98' and '11', but there is also C++03 standard that
should be supported. When CXX_EXTENSIONS property is ON, "-std=gnu98" should be
used, "-std=c++03" otherwise.

C++14 standard is now finalized, so it could be added to CMake as well.
GCC supports it since 4.8, Clang has complete support in version 3.4. MSVC 2013
also supports some C++14 features, but it does not need to be asked for enabling
them.

C++17 also may be enabled in newest clang by passing "-std=c++1z" argument. Not
sure whether you are keen to standard drafts support to CMake, but you could add
it as '1z' and then remove it when c++17 is finally published. I would not use
'17' as its name, as name may be changed (C++11 was initialially called c++0x,
because it was supposed to be published before 2010).
