[chenguoping76]

run VVAS-VVAS_REL_v1.1/build_install_vvas.sh Edge for k26 bsp, the script report 'Vitis AI 2.0 is not installed in the target sysroot'.

The sysroot is build according to https://www.hackster.io/jack-bonnell2/xilinx-kv260-petalinux-2021-1-build-vitis-ai-libraries-dd3025 instructs. Below is user-rootfsconfig:
CONFIG_packagegroup-petalinux-vitisai

CONFIG_xrt
CONFIG_xrt-dev
CONFIG_zocl

and sure success finish petalinux 2021.2 build [INFO] Successfully built project, then using sdk.sh export the sysroot folder.

I check the build_install_vvas.sh, and found it wish libvart-util.so.2.0.0, but using meta-vitis-ai method, there build a libvart-util.so.1.4.0 edition, so the VVAS-VVAS_REL_v1.0 should be use

after config ubuntu 18.04 according to
sudo apt-get install python3 python3-pip python3-setuptools python3-wheel ninja-build
pip3 install meson
pip3 install ninja
Above steps installs meson in /home//.local/bin/meson, so change PATH env to point using
export PATH=/home//.local/bin/meson:$PATH

cited from readme of VVAS-VVAS_REL_v1.0, there also have some errors:
