Could not find or use auto-linked library

[kkivan]

Got this error when trying to run the target with the GraphViz package GraphViz installed with Homebrew, works perfectly as cli in terminal

The issue is with M1 Macs only.

ld: warning: Could not find or use auto-linked library 'gvc'
ld: warning: Could not find or use auto-linked library 'cgraph'

In my case I was missing the Xcode Command Line Tools. Ran xcode-select --install, reinstalled the dependencies and all good.
