strange, it was working with those TWO lines in Slackbuild:

EXTRA_LIBS=" -lOpenCL -lSvtAv1Enc -lvpl -ldav1d -lxvidcore -lass -lbluray
-lsnappy -lzimg -lplacebo -lshaderc_shared" \
                                                 FFMPEG_EXTRA_CFG="
--enable-libvpl --disable-doc --enable-opencl --enable-libsvtav1
--enable-frei0r --enable-libdav1d --enable-libzimg --enable-libxvid
--enable-libass --enable-libbluray --enable-libsnappy --enable-libshaderc
--enable-libplacebo --enable-vulkan --disable-debug
--extra-cflags=-I/usr/local/include/vpl
--extra-cflags=-I/usr/include/svt-av1" \

be sure to export both?

You can't use something.pc in -L statement directly, it sets directory
where linker looks for libraries.

pkg-config is basically program (from system -  I saw it on Linux distros
and NetBSD's pkgsrc) that checks those *.pc files and helps to construct
include and libs lines.

-I is also sets include search *directory* and not a file, as far as I
understand.

But yeah, for example cmake sometimes mis-set those, so I tend to try and
fix this on my slightly non-standart system. Or just give up and symlink
few things into /usr
