Build fails with Python-3.7 pip 10 due to ninja?

[ozak]

I was following the instructions provided here by @fjperini and the build fails. The error I get is

ninja: build stopped: subcommand failed.

I tried installing ninja using pip3 before installing qgis but that failed too, so I imagine it may be related to this?
