SWUpdate ERROR : feature 'archive' required - yocto

Question

I am attempting to use SWUpdate to update my device kernel and device tree. However I am getting the error ERROR : feature 'archive' required. I have been told to configure SWUpdate to include archive then build it. To do this I run bitbake -c menuconfig swupdate. This creates a .config file which I use as a defconfig.
I have my bitbake file swupdate_%.bbappend which places this into the build
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
SRC_URI += "file://defconfig"
DEPENDS += " libarchive zstd"
My question is how do I properly configure and compile the SWUpdate recipe to include the archive library?
If I run bitbake -c menuconfig swupdate and enable ZSTD, archive, and SystemD followed by bitbake swupdate I get errors that zstd, archive and systemd headers cannot be found. Edit 1: This is resolved by adding DEPENDS += " libarchive zstd systemd" to the bitbake file. This then breaks my overall build. So it seems my real issue is I cannot properly get the defconfig into my image.
I found many repos on GitHub and I copied their folder structure and used their bitbake files to inspire my own. However when I get to building I get the error mentioned above. Can anyone point me in the right direction? I am willing to share more if needed.
Edit 2: I removed the defconfig from here and my project. I found that SWUpdate supports the function bitbake -c diffconfig swupdate. After making my changes I get an output file /build-fb/tmp/work/cortexa7t2hf-neon-poky-linux-gnueabi/swupdate/2021.11-r0/fragment.cfg with the contents
CONFIG_SYSTEMD=y
CONFIG_ZSTD=y
CONFIG_ARCHIVE=y
CONFIG_LOCALE=y
I added this to my defconfig and built my image. Same issue.
Edit 3: I want to show how I build my image.
source setup-environment build-fb/
bitbake -c cleanall mainapplication-dev
bitbake mainapplication-dev
I take the image generated and program my SD card. Then I run
bitbake -c cleanall smg-image-swu
bitbake smg-image-swu
This creates my .swu file which I place onto the device using FileZilla. I then run swupdate -v -i smg-image-swu-imx6ull14x14evk.swu and get the following output:
root#imx6ull14x14evk:~# swupdate -v -i smg-image-swu-imx6ull14x14evk.swu

Answer 1

The solution to this is to edit the above bbappend file to
FILESEXTRAPATHS:prepend := "${THISDIR}/files:"
SRC_URI += "file://defconfig"
DEPENDS += " libarchive zstd"
