tegra_multimedia_api missing after jetpack install

I just can’t seem to get /usr/src/tegra_multimedia_api installed using sdkmanager for Jetson AGX Xavier.

Downloading the source from https://developer.download.nvidia.com//assets/embedded/secure/tools/files/jetpack-sdks/jetpack-4.2.2/JETPACK_422_b21/P3310/Tegra_Multimedia_API_R32.2.1_aarch64.tbz2 doesn’t compile because of some missing libraries (eg -lcudart/-lnvinfer/-lnvparsers) …

All Jetson SDK Components are selected:
CUDA
AI
Computer Vision
NVIDIA Container Runtime
Multimedia
DeepStream

What’s the official way to to get these demos working?
