Skip duplicated items when generating build command

For some of the compiler settings, duplicate items can be
omitted (e.g. include_dirs, frameworks, libs, ...). The
order of the item is important, so changing the storage
to std::set<T> would not work (and this would break with
recursion anyway).

Instead add support to the code generating to compiler
command-line to skip over duplicated item when it make
sense.
