rk1808 wont build at default config (from github manifests)

Hey, rk1808 repository will not build. Its missing rknpu, and also missing many other rkmedia libraries etc
Can you look into it?

https://github.com/rockchip-linux/manifests

$ repo init --repo-url=https://github.com/rockchip-linux/repo --no-clone-bundle -u https://github.com/rockchip-linux/manifests -b master -m rk1808_linux.xml
$ repo sync --no-clone-bundle

When I download the sdk like this, and then use envsetup.sh, and then choose rk1808, then try to build it, I get several errors (all missing headers and libraries)

Anyone else have the same issue ??
