 Summary of the bug:
 How to reproduce:

 I'm trying to build ffmpeg from the last master branch version on an
 ubuntu desktop 20.04.04. Cuda libraries are installed. When i configure:

 {{{
 $ ./configure --enable-nonfree --enable-cuda-nvcc --enable-libnpp --extra-
 cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64

 ERROR: libnpp not found

 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
 ffmpeg-user at ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat.
 Include the log file "ffbuild/config.log" produced by configure as this
 will help
 solve the problem.

 }}}

 I'm attaching the mentioned ffbuild/config.log file. As you can see it
 says he cannot find npp.h, but npp.h is present in
 /usr/local/cuda/include, passed as extra cflags.
