Probably worth looking closely at the Python docs on the stable ABI at
https://docs.python.org/3/c-api/stable.html. It does say to not link
against the versioned dll on Windows.

<br>
I&#39;m currently trying to get the python stable ABI to work in our projec=
t.<br>
According to the documentation I only have to add <br>
`target_compile_definitions(_${PYTHON_WRAPPER_NAME} PUBLIC<br>
Py_LIMITED_API=3D0x03040000)`<br>
to my existing CMake project. Under my ubuntu 20.04 test system this worked=
<br>
and I could use any other Python version.<br>
But under Windows (10) I&#39;m still limited to the python version I used t=
o<br>
build it.<br>
If I use any other python version I get the following error:<br>
`ImportError: DLL load failed while importing _Pyswig_test: The specified<b=
r>
module could not be found.`<br>
_Pyswig_test being the name of my test project. Everything is in the same<b=
r>
directory.<br>
It did change something during compilation as it now links against<br>
python.lib instead of the previous python38.lib.<br>
Do I have to do something special to make the stable ABI work under Windows=
?<br>
<br>
With best regards<br>
