Looking at the CMake code, I think this python path was hard coded into the installed ITK. So maybe it's only valid for the build?
Ideally the ITK::ITKNumpyModule would have an INTERFACE dependency on the imported target
Python::ModuleorPython::SABIModule. This should produce a portable configuration. However, would likely need to be part of a larger refactor to use the import Python interface.Given that this path previously generated in the install was invalid here are a couple options:
$<BUILD_INTERFACE: >generator expression in the Numpy module.pixienvironment is not created in the source directory. This just side steps the underlying issue.thewtex commentedon Feb 3, 2026
Yes
And we do have an exceptional case with libpython where we are weakly linking.
Yes; the pixi environment in the source directory is intentional.
👍 did you want to have copilot give this a try?

@thewtex the merge of #5665 should have resolve this issue. Please test and close if resolved.
