1. Add some comments explaining what headers and libs are expected on what systems 2. Only look in default incdirs if no incdir is specified 3. Require libnvbufsurface.so on Jetson when cuda-nvmm=enabled 4. Require libatomic on Jetson when cuda-nvmm=enabled Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8021>
