@koahnig said: Either you need to add "-j4" as make parameter to each of your projects. Otherwise you can set also "MAKEFLAGS=-j4" to your environment (e.g. for a kit as suggested above). Correction to above post. I have set it to system environment. I did not get it to work in kit environment. Both were set due to my trials, but the latter alone (in kit environment) does not help.
