2356 dnl Look for the ncurses library.  This is a little complicated on Linux,
2357 dnl because it may be linked with the gpm (general purpose mouse) library.
2358 dnl Some distributions have gpm linked with (bsd) curses, which makes it
2359 dnl unusable with ncurses.  However, we don't want to link with gpm unless
2360 dnl ncurses has a dependency, since gpm is normally set up as a shared library,
2361 dnl and the linker will record a dependency.
2362 dnl
2363 dnl The optional parameter gives the root name of the library, in case it is
2364 dnl not installed as the default curses library.  That is how the
2365 dnl wide-character version of ncurses is installed.
