Yes, you need to have the NVidia Video SDK when you build.

./configure --prefix=/usr --bindir=/usr/bin --datadir=/usr/share/ffmpeg --incdir=/usr/include/ffmpeg --libdir=/usr/lib64 
--mandir=/usr/share/man --extra-cflags=-I../Video_Codec_SDK_7.0.1/Samples/common/inc [...] --enable-nvenc [...] blah blah blah

The path --extra-cflags=-I is to the nvEncodeAPI.h file needed and --enable-nvenc adds the h.264 encoder

See ./libavcodec/nvenc.c
