 The above command will configure the installation path to ```/usr/local/opt/ncurses```. You can also change the path as needed. After compilation and installation are complete, you should be able to find the libncurses library file in the specified installation path. With the above steps, you can successfully compile and install libncurses on macOS. Please note that the process may change due to version updates.
