If you can use the MSYS2 environment from Powershell (some MSYS2 things work directly in Powershell, others need a Bash shell) then you can simply add -DWITH_PYTHON=ON to the CMakeArgs in jhbuild and build it. Don't run the installer, just add c:\gcdev64\gnucash\stable\inst\lib\python3.11\site-packages to PYTHONPATH and run your scripts.

Ah, missed that. It's not even 3.11:

That wouldn't work even if it was a 32-bit build because it's a different version of python and the cpython folks don't maintain ABI across versions. For best results use C:\Users\mu\Entwicklung\GnuCash\gcdev64\msys2\mingw32\bin\python3, making sure to set up the environment accordingly. The easiest way to do that is to use the Mingw32 shell from Start>MSYS2.
