LinuxでNVENCをサポートするffmpegのコンパイルを手伝ってください。

以下を使用してNVENC対応obs-studioを構築できるように、NVENC対応ffmpegを構築しようとしています。これはガイドです。多くの悩みの終わりにすべての依存関係を解決し、今この時点に達しました。しなければならないルールファイルを編集してffmpegをコンパイルできるといいでしょう。しかし、私の信頼できる端末は私に次のような内容をエクスポートしました。

これは私のffmpeg/debian/rulesファイルです：

#!/usr/bin/make -f

export V=1

# sets DEBIAN_VERSION variable
include /usr/share/dpkg/pkg-info.mk

# Get the Debian version revision:
DEB_REVISION := $(word 2, $(subst -, ,$(DEB_VERSION)))

# sets DEB_HOST_* variables
include /usr/share/dpkg/architecture.mk

# Ubuntu ld adds -Bsymbolic-functions by default, but that prevents FFmpeg from building.
export DEB_LDFLAGS_MAINT_STRIP=-Wl,-Bsymbolic-functions

# Package name for the extra flavor.
EXTRA_PKGS := $(shell sed -nr 's/^Package:[[:space:]]*(.*extra[0-9]+)[[:space:]]*$$/\1/p' debian/control)
FLAVORS = standard extra static

# Enable as many features as possible, as long as the result is still GPLv2+ (a GPLv3+ variant is built as libavcodec-extra/libavfilter-extra flavor).
# The following flags (and build-dependencies) are not added, because they would require a libavformat-extra flavor:
#   --enable-libsmbclient           (libsmbclient-dev [!hurd-i386 !m68k !sparc64])
# The following flags are not added, because the necessary libraries are not in Debian:
#   --enable-decklink
#   --enable-libcelt                (see #676592: removed from Debian as abandoned upstream, replaced by opus)
#   --enable-libdcadec
#   --enable-libilbc                (see #675959 for the RFP bug)
#   --enable-libkvazaar
#   --enable-libmfx
#   --enable-libnut
#   --enable-libopenh264
#   --enable-libopenmpt
#   --enable-libschroedinger        (see #845037: removal due to security issues)
#   --enable-libutvideo
#   --enable-libvidstab             (see #709193 for the RFP bug)
#   --enable-libxavs
#   --enable-libzimg
# The following flags are not added for various reasons:
#   * --enable-librtmp:             ffmpeg has better built-in RTMP support with listen mode.
#   * --enable-libv4l2 [!hurd-any]: This is only needed for very old devices and may cause problems for others.
#                                   Should anyone need it, using LD_PRELOAD pointing on libv4l2 has the same effect.
#   * --enable-opencl [!hurd-any]:  This is considered an experimental API.
