Does Windows machines also have ISPC v1.30.0, installed?
Since we didn't install ISPC ourselves on Windows, should we somewhere check the ISPC version? To make sure that ISPC on Windows machines doesn't change abruptly.

Sorry I did install ISPC myself on the Windows machine and it won't change abruptly because we don't use the bundled Blender one. I think its 1.29.0, I will update it before merging this PR, thanks

Just checked, Window is already using 1.30.0, lucky :P

tar xf ispc.tar.gz && cp -r ispc-v1.30.0-linux/bin /usr/ && cp -r ispc-v1.30.0-linux/include /usr/ && \
