The missing macros are #define'd in /usr/include/sys/fcntl.h: 

127:#define	O_NONBLOCK	0x0004		/* no delay */
188:#define	F_GETFL		3		/* get file status flags */
189:#define	F_SETFL		4		/* set file status flags */

The reason for this behaviour is clear, sys/fcntl.h is never included on __APPLE__ computers:

When CMake configures the software it checks for the existence of C header files, so sys/fcntl.h should be added to that list in, presumably, CMakeFiles/CMakeConfigureLog.yaml?

You mean it takes a long time until the text appears in the browser's window? This is why encounter since some time…

Maybe GCC7 is an appropriate compiler?

I tried to use another patch that includes fnctl.h instead od sys/fnctl.h – and it makes no (visible) difference…
