As previously discussed we'll now target C++17 instead of just C++11, so this updates the CMake to reflect that change.
This also gets rid of manually adding --std=xxxxx for Unix targets.
This should not be needed as setting CMAKE_CXX_STANDARD should do that for us.
By manually adding --std=xxxxx the compiler invocation would probably end up with multiple arguments specifying the language version.
