[CMake] Linking on OSX

[Juan E. Sanchez]

Hello,

It looks like you are making progress.  Note that to use the gcc-8 and 
g++-8 compilers from brew, you need to have include files in 
/usr/include.  Otherwise you get strange errors about missing _stdio.h, 
etc.  I believe in another thread, someone suggests how to make sure the 
headers get put in the right place.

I looked and found curses.h (not ncurses.h) here.
/usr/include/curses.h.

Regards,

Juan
