Mmm. That huge space is actually coming mostly from the few hundreds of
100-MB statically-linked examples... which we don't even install. Do we
really need to enable -DBUILD_EXAMPLES=ON, actually? At least, we could
avoid uselessly building the unused static version with the attached
change. That'll reduce disk usage from tens of gigabytes down to a few
gigabytes, and probably reduce the build time a lot as well.
