Why is that wrong?  As you said it has both `ncurses.h` and `curses.h`.
Even though they are symlinks one can still use them to compile.

To ignore the symlinks one could configure with

  -DCURSES_INCLUDE_PATH=/usr/include/ncurses

to tell FindCurses to skip searching and just use that.  Once it has
that directory the computation of the other values may work.
