How to get out-of-source builds to use all threads

I’m attempting to build another branch of Blender in a custom directory on my Arch Linux system (under blender-git directory). When simply running make full, under the blender directory, all 16 threads are used on my computer. However, when I generate the make files under a custom director and run make, only one core is used.

How do I get make to use all threads, as per usual with standard Blender builds? Just want to speed up the process, so that I can test certain branches quicker with less build times.

You can pass the number of threads to make with the -j parameter

Why do I feel like I should’ve known that? LOL!!! I use -j12 and -j16 in some of my make commands.

Thanks for the refresher.
