Nice trick. Does it get ncurses to auto-disable the C++ stuff?

Yes, but has anybody wanted a non-UTF-8 enabled ncurses in the past 10
years?? It seems like the default should be to build the one people
actually want. With the current default, there's a major risk of
accidentally building the wrong one and building your whole system on
it, then realizing your system is broken, has the wrong ABI, and needs
to be rebuilt from scratch...

Bleh; what do mainstream distros do then?

I suspect it does not support UTF-8...
