running CubiCal natively on ILIFU

@IanHeywood noting this here for lack of a better place to put it (where would you put it?)

So I've git CubiCal running natively on ilifu without containers.

• Make a python3 virtualenv

• pip install from this branch: removed cacacore==3.0.0 requirement #375 (or use master and simply remove the ==3.0.0 requirement on python-casacore in setup.py)

• It still needs to find casacore data, which is not installed on the nodes. But that's just a directory. Put this in your ~/.casarc:

  measures.directory: /users/oms/casacore-data
  

  ...or copy casacore-data to your own home if you wish and adjust the path.

In that spirit, I'm trying a native DDFacet build without invoking singularity. Guess the only way out of cmake not being available is a "Dear Support"?
