The patched kernel and fundamental Xenomai kernel modules must be
installed and loaded as root, but can in principle be built by any user.
The userland Xenomai libraries could be built by any user but (for my
systems anyway) are installed in areas requiring root permissions. Code
you build yourself on top of userland Xenomai can be built by any user
(this is what I do), but must be run with a subset of root permissions
to allow setting thread priorities etc.
