vcpkg silently ignores overlay-ports

[Nullarity]

The following command is not using my custom port:

vcpkg install protobuf --overlay-ports=/home/dmitry/customports --debug

vcpkg output:

Environment

• OS: Linux (Ubuntu)
• Compiler: gcc 11.4

Expected behavior
I expected the command to use my custom port or at least provide an indication (in debug mode) of why the custom port was omitted.

It is your responsibility to make sure that overlay-ports dir contains your ports.
You should use /home/dmitry/customports/ports or get rid of ports subdir.

@Osyotr Got it, thank you.
