can be disable by passing NO_WIDECHAR=ON.

Advance cmake options:
- `-DSHARED_TOXCORE=ON` (default `OFF`) <20> Build Core as a shared library.
- `-DUSE_NACL=ON` (default `OFF`) <20> Use NaCl library instead of libsodium.
- `-DNO_WIDECHAR=ON` (default `OFF`) <20> Disable wide char in toxic.
Note that you should call cmake on the root [`CMakeLists.txt`](/CMakeLists.txt) file only.

# If NCurses is required, use the function wsyncup() to check if the library
# has NCurses functionality (at least this is where it breaks on NetBSD).
# If wsyncup is in curses, use this one.
# If not, try to find ncurses and check if this has the symbol.
# Once the ncurses library is found, search the ncurses.h header first, but
# some web pages also say that even with ncurses there is not always a ncurses.h:
# http://osdir.com/ml/gnome.apps.mc.devel/2002-06/msg00029.html
# So at first try ncurses.h, if not found, try to find curses.h under the same
# prefix as the library was found, if still not found, try curses.h with the
