sip-build: There are no bindings that can be built

Sun May 29 13:37:05 BST 2022

Thanks. Indeed. After fixing some path issues, now hopefully the right 
tools are used.

It still did not work with the installed sip 6.6.1 from PyPI, which 
leads to: sip-build: '13.2' is not a supported ABI version

After installing sip from the repo, finally, 'The project has been 
built.' So far, so good.

Now, the top level directory, however, does not contain a make file, so 
make fails. Running make in the build directory, fails with a linker error:
