undefined symbol: sipExportedExceptions_limacore

[Laurent Claustre]

Dear Phip,

so, should we move to the recipe for "Package Projects" you describe 
here 
https://python-sip.readthedocs.io/en/stable/examples.html#package-projects ?
we have lima-core depending of processlib then we will have to port 
about 30 others "extra" projects (lima-camera-xxxxx) which depend on 
lima-core.
