Now I get working binary of libcdio including cd-paranoia by talking with
libcdio develop team.
Note:
1. Currently, their git head only works with macOS High Sierra, Not official
release (0.94)
2. Git head need to comment output manuals.
3. I noticed that these tools have to unmount Audio CD to work properly...

But this time I got linker error like the following when configuring ffmpeg
with --enable-libcdio option.

clang: error: linker command failed with exit code 1 (use -v to see invocation)
ERROR: No usable libcdio/cdparanoia found
I can't understand why such kind of error occurs even though binary level of
libcdio work...
Do you have any idea?
I build libcdio and libcdio-paranoia with option --disable-shared. if tools of
libcdio works, library "libcdio.a" also build correctly am I wrong?
How can I know the library "libcdio.a" correctly build?
Note:
The above error is on macOS High Sierra GM Candidate. With macOS Sierra, I get
more worth linker error...
