A parallel `cmake --build` with a Makefiles generator interleaved the output of concurrent recipes. When CMake is the one passing the parallel flag and a build-time probe finds GNU Make 4.0 or newer, append `-Otarget` so each recipe's output stays grouped. A native `-- -j` leaves the job count unset and opts out. Honor `USES_TERMINAL` under grouping by prefixing such recipes with a `$(CMAKE_USES_TERMINAL_PREFIX)` variable, empty by default and set to `+` next to `-Otarget`, so interactive commands stay unbuffered. Fixes: #27510
