I agree that this should be done, but the implementation is slightly
more complicated than that:

CONFIGURE_DIRS can be a list of directories, so the infrastructure
would need to create a build directory for each of them, probably use
'..' as CMAKE_ARG_PATH, and set BUILD_DIRS correspondingly.

If you are working in this area, I'd also love to see a switch to use
ninja as default builder instead of make.
