Need a better solution for the sip recipe

[leofang]

While #15 supports the most recent version 4.19.18, note that since PyQt 5.11 a private copy of sip needs to be built: https://www.riverbankcomputing.com/static/Docs/PyQt5/installation.html#downloading-sip
that is, for the purpose of supporting PyQt5, the flag --sip-module PyQt5.sip needs to be used when building sip, otherwise there would be a ModuleNotFoundError for PyQt5.sip. But, adding that flag also means import sip no longer works.

Currently, #15 does not have that flag, so a PyQt 5.12 recipe (corresponding to recently merged PR conda-forge/qt-feedstock#110) can not depend on conda-forge's sip anymore. Any suggestion?

This is for resolving conda-forge/pyqt-feedstock#58.

No up to date package should be using a top-level sip module.

See source. I guess this eliminates the majority need of having a standalone sip package except for backward compatibility...

Closing this issue. Note that starting conda-forge/pyqt-feedstock#61 PyQt5 no longer depends on the sip package; a private copy of sip is built and shipped with it.
