Yeah, looks like --build is called with no explicit parallelization:

https://github.com/juce-framework/JUCE/blob/2f980209cc4091a4490bb1bafc5d530f16834e58/extras/Build/juceaide/CMakeLists.txt#L93-L98

Try

export CMAKE_BUILD_PARALLEL_LEVEL=4

https://cmake.org/cmake/help/latest/envvar/CMAKE_BUILD_PARALLEL_LEVEL.html#envvar:CMAKE_BUILD_PARALLEL_LEVEL

I can confirm this breaks the task up across cores.

Yeah that fixes it I believe, I'm guessing you could use nproc to determine the user's core count.
