Building gem5 targets on Mac with M4 and Homebrew

[Qsionc]

Hello,
I did not want to start an issue, this is something I could resolve locally and I need simple help.

It would seem that the lld linker does not see my LD_LIBRARY_PATH or something, where I have defined a list of folders too look for libraries, namely /opt/homebrew/lib folder, where I have libpng present. During build, the linker does not find libpng (ld64.lld: error: library not found for -lpng altough when I dry-run linker manually while providing additional -L /opt/homebrew/lib option, it does not complain about missing library). I wish to try and edit build configuration for, lets say, X86 target, so I can add my own additional options to scons that pass additional linker options in the future.

Where can I start my search, so I could for now manually add -L /opt/homebrew/lib option to the lld linker? Tried looking through code, but I lost patience.. ^_^'
