read the cmake docs, ask at #cmake or: have a look at how it's already
done a lot of times.. 
eg:
pkgs/applications/misc/qgis_svn/default.nix (cmake ... -DPATH=...)
You can check wether the curses libs have been found be opening
CMakeCache.txt file.
The one contains (after configuring!):

    //Path to a file.
    CURSES_INCLUDE_PATH:PATH=CURSES_INCLUDE_PATH-NOTFOUND

    //Path to a library.
    CURSES_LIBRARY:FILEPATH=CURSES_LIBRARY-NOTFOUND

    //Path to a library.
    CURSES_NCURSES_LIBRARY:FILEPATH=CURSES_NCURSES_LIBRARY-NOTFOUND

Those are the options you can set by -D..=value

But I've fallen into this trap as well. So I
guess we should add some documentation? Maybe directly within the cmake
expression file? Would you have had a looked at that file?

Another thing you can try is passing pkgconfig as buildInput as well.
Sometimes deps are found automatically that way.

If you still have trouble enhancing cmake let me know.

Sincerly
