you need to run "make".
cmake create only the Makefiles

Basically the source you are trying to build:
- accept only clang (we have, with some difference from the author,
   but it is not our default)
- accept only GNU LIBC++ (we don't have)
- requires "-std=gnu++1z" (a proposed standard that could be rejected in 
part)

Conclusion:
the Author cares only that the program builds for himself
and not on other platforms.
