How to Build Oleo on Cygwin

Question

I am trying to install Oleo (http://www.gnu.org/software/oleo/) on a Cygwin setup and am running into some issues. In the linking stage, the build errors out, complaining about undefined references in ncurses. I have the libncurses-devel packages installed.

The commands I ran to build were:

me@mymachine$ CFLAGS="-I/usr/include/ncurses" ./configure
[configure chatter, then success]
me@mymachine$ CFLAGS="-I/usr/include/ncurses" make
[snip successful compile...]
io-curses.o:io-curses.c:(.text+0x1ef8): undefined reference to `_ncwrap_stdscr'

io-curses.o:io-curses.c:(.text+0x21f4): undefined reference to `_wrefresh'

Does anyone have any ideas what may be causing these ncurses issues?

You may need to add -lcurses or -lncurses to CFLAGS for successful compiling.
