Feat: The install script is interfering with other installs on macOS #105

[Cevedale]

You had a problem with the installation of "cairo-lang" that was interfering with your "starknet_in_rust" project, causing errors during compilation and testing. The temporary solution was to uninstall "cairo-lang" and remove the "CARGO_MANIFEST_DIR" environment variable.
I'll write some possible issues that caused this problem:
Check if the "CARGO_MANIFEST_DIR" variable is set correctly and not causing conflicts.
Examine the dependencies and build tools of your "starknet_in_rust" project to ensure there are no conflicts with "cairo-lang."
Try to pinpoint the exact source of the conflict by uninstalling "cairo-lang" and checking if the problem persists.
If the issue continues, you might seek help from the online communities of the involved projects.
Check if both projects are up to date with the latest versions.
Verify system and dependency compatibility.
If "brew" is causing conflicts with "cairo-lang," consider using an alternative package manager or building "cairo-lang" from source.
