configure: error: Need pkg-config to enable libusb support - yocto

Question

I'm new to yocto, my goal is to add a printer driver to the yocto image of imx6 so that we can access the priter from the board. i was trying a build, following the instructions at IMXLXYOCTOUG.PDF.
$ DISTRO=fsl-imx-xwayland MACHINE=imx6qsabresd source fsl-setup-release.sh -b build_dir
$ source setup-environment build_dir
$ bitbake fsl-image-qt5-validation-imx
the basic build was successful, i brought up the board with gui, things were fine.
i wanted to add printer support to the image, so ive added meta-printing (https://github.com/rossburton/meta-printing) layer. i've updated bblayer.conf
BBFILES ?= ""
BBLAYERS = " \
${BSPDIR}/sources/poky/meta \
${BSPDIR}/sources/poky/meta-poky \
\
${BSPDIR}/sources/meta-openembedded/meta-oe \
${BSPDIR}/sources/meta-openembedded/meta-multimedia \
\
${BSPDIR}/sources/meta-freescale \
${BSPDIR}/sources/meta-freescale-3rdparty \
${BSPDIR}/sources/meta-freescale-distro \
**${BSPDIR}/sources/meta-printing \**
as per the instruction in README from github.
Later after booting i was not able to access lp command to print some sample file with the printer. so i added
IMAGE_INSTALL_append = " cups"
in local.conf file which is giving me this error below..

i have the pkg-config installed on my host PC
$ pkg-config --version

Any idea why
configure: error: Need pkg-config to enable libusb support.
is happening.
or
is it the right way / is there any better methord to get the lp command running on imx6 through yocto. so that i can access the printer..
any input is apretiated..
Thank you.

I've solved the same. actually I've added meta-printing layer to get the access to cups. but cups were already existing along with the meta layer in poky (imx-yocto-bsp/sources/poky/meta/recipes-extended/cups). so I removed meta-printing layer & then updated build/conf/local.conf with
IMAGE_INSTALL_append = " cups"
This worked for me and after booting I was able to use lp, lpadmin etc.. commands on my imx6 board.
