Xcode build rules script "command not found" on M1

I have a project that runs some utility I've installed using homebrew on one of its build rules.

On my M1 mac, homebrew is installed on /opt/homebrew/bin.

I have eval "$(/opt/homebrew/bin/brew shellenv)" present in my ~/.zprofile file, but it seems like Xcode doesn't respect that (or maybe overrides it?).

When trying to evaluate the PATH variable during Xcode run script command I get the following:

PATH=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin:/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/local/bin:/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/libexec:/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/usr/bin:/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/usr/local/bin:/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/local/bin:/Applications/Xcode.app/Contents/Developer/usr/bin:/Applications/Xcode.app/Contents/Developer/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

For clearance, this is the phase I was running, under Build rules. Image showing the script i've ran

I've managed to find two workarounds that work with this issue, the first is to symlink the program you want from /opt/homebrew/bin onto /usr/local/bin (protoc in my case)

sudo ln -s /opt/homebrew/bin/protoc /usr/local/bin/protoc

The second is to add the following line to the build rule script:

eval "$(/opt/homebrew/bin/brew shellenv)"

This has the disadvantage of not working on non M1 Macs.
