Subject: [PATCH] BUG: Implement cmake -E build build_dir (#12446).

This was not finished when implemented, and it just spits out the usage when
attempting to use the command.

The command now executes as expected.

The '-E build build_dir' command was created, but never implemented.  Its
functionality is provided by the --build option.
