These are installed in the directory containing the Python interpreter 
that is executing sip-install. If you want an isolated build of PyQt you 
would normally create a venv for that purpose, install sip5 into that 
venv and run sip-install in that venv. Is that a problem?

I admit that the provision of the --target-dir option but not a 
--bin-dir option is inconsistent. However my preferred fix for that is 
to deprecate the --target-dir option.

There are other files potentially copied into the Qt installation 
(Designer and Qml plugins and QScintilla .api files).
