Yocto Transaction Test, two recipes install the same file - embedded-linux

Question

I am adding a custom recipe to my image. It is bases on DBCPPP. This project is built using cmake. My issue only comes to light when I include a new layer meta-swupdate. It seems meta-swupdate alters the kernel in a way that conflicts with dbcppp. My full error is:
Error: Transaction test error:
file /usr/lib/libxml2.so.2.9.10 conflicts between attempted installs of dbcppp-1.0+gitr0+fa8ce17468-r0.cortexa7t2hf_neon and libxml2-2.9.10-r0.cortexa7t2hf_neon
To build and include dbcppp I added the recipe:
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
SRC_URI = "gitsm://github.com/xR3b0rn/dbcppp.git;protocol=https;branch=master"
PV = "1.0+gitr${SRCPV}"
SRCREV = "${AUTOREV}"
DEPENDS += " boost"
S = "${WORKDIR}/git"
inherit pkgconfig cmake
FILES_${PN} += "/usr/lib/xml2Conf.sh /usr/lib/lib*.so.*"
SOLIBS = ".so"
FILES_SOLIBSDEV = ""
INSANE_SKIP_${PN} += "dev-so"
I have read a few other questions and attempted two solutions by adding a do_install_append step.
Change folder permission level install -d 0755 ${D}/usr/lib
Remove the folder rm -rf ${D}/usr/lib
Neither solution worked. I need both libraries in my application and I unsure how to proceed.
Edit: After some further reading I found a suggestion to delete the tmp, cache, and sstate-chace folders. I did this but I receive the same error.
Edit: My local.conf has PACKAGE_CLASSES ?= 'package_rpm' defined. if I remove this I still get a do_rootfs error, but the error message is not helpful.
Edit: In my recipe for dbcppp I have attempted to remove the file in question. This gives me the same error. Makes no difference.
do_install_append() {
rm -rf /usr/lib/libxml2.so.2.9.10
}
