Set CMAKE_XCODE_ATTRIBUTE_CLANG_CXX_LANGUAGE_STANDARD based on selected CMAKE_CXX_STANDARD #204

This is an issue that has been opened for 4+ years on CMake.

Adding it to the toolchain is a workaround until CMake finally "fixes" it.

In most cases, simply adding set(CMAKE_XCODE_ATTRIBUTE_CLANG_CXX_LANGUAGE_STANDARD "c++${CMAKE_CXX_STANDARD}") works, tho it will not work with GNU extensions.

The same can be done for C_STANDARD.

you should use gnu++${CMAKE_CXX_STANDARD}
