How do I fix an openssl error when compiling nctl on MacOS?

When attempting to run nctl-compile on MacOS, you may receive the following error: 'error: failed to run custom build command for openssl-sys v0.9.67'.

If you issue the command brew info openssl it will return info that appears similar to the following:

...
For pkg-config to find openssl@3 you may need to set:
    export PKG_CONFIG_PATH="usr/local/opt/openssl@3/lib/pkgconfig"
...

The next step is to issue the above command. In this example, you would use PKG_CONFIG_PATH="/usr/local/opt/openssl@3/lib/pkgconfig".

After this, nctl-compile should work correctly.
