# \subsection{NCurses library configuration}
# Add \verb+open configure/ncurses+ line to your \verb+OMakefile+ to get access to the following
# autoconfiguration variables.
# \varlabel{NCURSES_AVAILABLE}{NCURSES\_AVAILABLE} A boolean flag that would be set when both
# the \verb+curses.h+ header, the \verb+term.h+ header, and the \verb+ncurses+ library very found.
#
# \varlabel{NCURSES_TERMH_IN_NCURSES}{NCURSES\_TERMH\_IN\_NCURSES} A boolean flag that would be set
# when \verb+term.h+ has to be included as \verb+<ncurses/term.h>+ instead of \verb+<term.h>+.
#
# \varlabel{NCURSES_CFLAGS}{NCURSES\_CFLAGS} The \verb+CFLAGS+ to use when compiling ncurses code.
# Will include \verb+-DNCURSES+ and \verb+-DTERMH_IN_NCURSES+, respectively
# when \verb+NCURSES_AVAILABLE+ and \verb+NCURSES_TERMH_IN_NCURSES+ are true.
#
# \varlabel{NCURSES_CLIBS}{NCURSES\_CLIBS} The \verb+LDFLAGS+ to use when linking ncurses code.
# Will normally contain \verb+-lncurses+ when ncurses is found and remain empty otherwise.
