that I'm just not seeing?

Qt Creator tries to be nice to building on the command line, so just do the
same you donthere: Export the MAKEFLAGS environment variable with the flags
you want each make call to have (-j4 in your case). Do that before starting
Qt Creator and it effects all builds using make triggered by Qt Creator. Or
have the kit set that variable if you only want it for builds with certain
kits.

For CMake I would recommend just switching to ninja as the build backend
though. That does parallel builds out of the box and seems much faster at
handling builds of projects where only a few files changed.
