Pip install odoo only works with editable (-e) installs

[sbidoul]

Impacted versions: all

Reopening #16700 that was closed by a bot. The issue remain valid for master.

Steps to reproduce:

In the Odoo root directory, with a recent pip and setuptools, run pip wheel . and/or pip install ..

Current behavior:

The resulting wheel file does only contain the base addon.
The resulting installation does not include the addons.

Expected behavior:

The wheel should include all addons in odoo/addons. The installation should include all addons in site-packages/odoo/addons.

Solution:

A robust backward compatible solution is proposed in #44001.

The solution in #44001 seems good except how would it work on windows? I could be wrong but I'm not sure symlinks would be working on windows. I guess it should at least not crash on windows and at least improve the state of things on Unix like OSes.

Symlinks work on NTFS if the user has the adequate permissions.
