Can you try what happens if you delete the build directory, re-create it, and then just use the minimal command line cmake /vol7/... ? Make things as simple as possible if you don't know what causes a particular problem. If the problem goes away, then repeat by adding one flag at a time until the problem re-appears -- at which time you know what change must have caused it. By the way, you are missing a space between the last two commands (FORCE_BUNDLED_BOOST=ON and -DDEAL_II_ALLOW...). But that is not the cause of the problem.
