Hi Ole:

The additional context you sent me off-list reads as follows:

-- Found PythonInterp: /usr/bin/python3 (found suitable version "3.5.4", minimum required is "3") 
-- Found PythonInterp: /usr/bin/python3 (found suitable version "3.5.4", minimum required is "2") 
-- Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython2.7.so (found version "2.7.13+") 
Traceback (most recent call last):
   File "<string>", line 1, in <module>
ImportError: No module named 'numpy'
-- WARNING: NumPy header not found. Disabling Python binding

This simply means you need to install the python3-numpy package
(to be consistent with the above python3), and all should be well.

Alan
