[tor-dev] tor-browser-build : any way to get it to use system packages for building?

Good day -

I recently attempted to check-out and build tor-browser-build - MUST it download ALL the gits, if system packages are found to satisfy version dependencies ?

I just don't have enough storage / network bandwidth . Why am I downloading the llvm source when I already have llvm and clang 13 (-devel packages also) on my Fedora 36 system ?

Is there any interest in producing a version of tor-browser-build to use installed system packages if they meet version requirements instead of checking out GITs & building for ALL dependencies ? It could be enabled with a USE_SYSTEM_PKGS=1 make option or something.

I'm going to have to develop this if I want to work on tor-browser, which I do want to do.

Best Regards, Jason
