This should happen 5.13 on, since we replaced the
forks of uic and rcc for the original tool provided by Qt,
since it's compatible with Python via (uic -g python some_file.ui)

Can you check if the pyside-tools sub repository is also on the 5.12 branch?
With something like: git submodule update -f
or you can go to sources and do that manually.

If you really want to build the project from source,
of course you should keep doing what you were,
but if you just want to use PySide, a pip install should be enough.

You can install specific versions doing a:

pip install pyside2==5.12.2

for example.

Let's know how it went.
