ERROR: frei0r.h header not found

Thanks for you contribution. But I encounter some mistakes when I use the following command line to build ffmpeg nvidia on my computer(centos7+cuda-9.0):

docker build . -t ffmpeg-nvidia

Then it reported following errors:

Removing intermediate container add32f2a69f0

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

Could you help me ? Thanks in advance.
