* Update wrap files * Ignore clang's warning in doctest: <ciso646> is not a standard header since C++20, use <version> to detect implementation-specific macros" [-Werror,-W#warnings] Make sure app/doctest.h is used everywhere instead of directly including the header, so the warning is disabled everywhere
