ERROR: \Path\To\mypkg\test_package\conanfile.py: option 'shared' doesn't exist
Possible options are []

You added shared to your profile, that applies to the test_package/conanfile.py.

Options need to be prefixed with the package you want to target, in this case: hello:shared=True, otherwise, they will apply to the downstream consumer, in this case the test_package/conanfile.py one, that doesn’t define this option and then it fails as expected.

[memsharded]

Your conanfile.py didn’t declare a shared option.

For some reason, you are not correctly following the instructions you linked. If you read the recipe it will contain:

options = {"shared": [True, False]}
    default_options = {"shared": False}

It seems you removed it or something.
