[cmake-developers] ncurses sub-dir and include path

[Christoph Grüninger]

Hi Brad,
thanks for keeping answering my emails!

CMake includes form.h, not (n)curses.h. So form.h is later not found,
because after finding (n)curses.h in /usr/include the search is over.

While this is true, my expectation are that CMake as the build tool of
my choice should be able to figure out its own dependencies without the
user to explicitly setting an include path.

I opened !3638 to get my issue fixed. We can continue discussion the
issue there.

Kind regards,
Christoph
