The current code does this:
if [ -f /usr/include/ncursesw/curses.h ]; then
echo '-I/usr/include/ncursesw -DCURSES_LOC="<ncursesw/curses.h>"'
elif [ -f /usr/include/ncurses/ncurses.h ]; then
echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses.h>"'
elif [ -f /usr/include/ncurses/curses.h ]; then
echo '-I/usr/include/ncurses -DCURSES_LOC="<ncurses/curses.h>"'
[...]
This is merely inconsistent:
- adding the full path to the directory in the -I directive,
- especially since that path is already a sub-path of the system
include path,
- and then repeating the sub-path in the #include directive.
Rationalise each include directive:
- only use the filename in the #include directive,
- keep the -I directives: they are always searched for before the
system include path; this ensures the correct header is used.
Using the -I directives and the filename-only in #include is more in
line with how pkg-config behaves, eg.:
$ pkg-config --cflags ncursesw
-I/usr/include/ncursesw
This paves the way for using pkg-config for CFLAGS, too, now we use it
to find the libraries.
