Parallel build use only one CPU/core
Running cmake --build . j8
gives me the following picture of the system load:
I.e., all forked commands somehow (I've run out of ideas HOW IS THAT POSSIBLE) bound to the first CPU (core)
Meanwhile running underlaid build tool (make
or ninja
) directly w/ the same -j
option runs on all CPUs/cores (as expected).
$ cmake --version
cmake version 3.27.0-rc3
