You need the header files in any case (to compile).  For the libraries -
there are (now that I'm reminded to look closely) three types of files:

	/bin/cygncurses7.dll
	/lib/libncurses.dll.a
	/lib/libncurses.a

It is the second of these which acts as an import-file (used in linking)
for the dll (normally this would be a ".lib" file, but cygwin is
different).  The last is supposed to be a static archive (but I recall
reading the cygwin still implements it as a shared library).

Both of the ".a" files are provided in the -devel package - so you need it
to link an executable as well.
