I've been trying to build UXP as XulRunner using these build instructions but i keep getting errors with SVE:

.../uxp/uxp/media/libvpx/libvpx/vpx_dsp/arm/vpx_neon_sve_bridge.h:16:10: fatal error: 'arm_neon_sve_bridge.h' file not found 3:37.48 #include <arm_neon_sve_bridge.h> ...

Is this possibly a known error?

I am using the UXP latest release and this .mozconfig:
