This should definitly be inside a if(UNIX). Obviously for buildroot that doesn't matter but for upstream it probably does.

Quoted 1 line

+VSXU_LICENSE = GPLv3

Only artiste_main.c is really GPLv3+, all the rest is GPLv2+ or LGPLv2.1+.
Also, the whole of cal3d is LGPLv2.1+. So I'd give it GPLv3+, LGPLv2.1+.

Quoted 1 line

+VSXU_LICENSE_FILES = COPYING

and add COPYING.LESSER here.

I guess there should be an optional dependency on jack and pulseaudio as well
(plugins/src/sound.rtaudio).
