How to change number of threads used in Homebrew builds? I'm trying to install Inkscape using Homebrew but the build process takes too long, and it's CPU intensive. So I'd like to pass the number of threads that would be used for the build command. Than way, at least I can use the computer for other tasks while the build process take place.
This is what I ended up using:

$ HOMEBREW_MAKE_JOBS=1 HOMEBREW_VERBOSE=1 brew install caskformula/caskformula/inkscape


HOMEBREW_MAKE_JOBS is the number of threads that wold be used in the build process by make and HOMEBREW_VERBOSE is set to one to turn on verbose mode for all tasks performed by Homebrew.
