FindPython's Development.Module component requires "LIBRARY" in the artifacts list
In my current environment find_package(Python REQUIRED COMPONENT Development.Module)
currently fails with Could NOT find Python (missing: Development.Module)
. The reason for this failure can be traced through the following parts of the code:
-
LIBRARY
is currently only added to_${_PYTHON_PREFIX}_FIND_DEVELOPMENT_MODULE_ARTIFACTS
) on Windows - Without
LIBRARY
in that list, we never enter this conditional block - Without entering that block, we never call
_python_get_version
- Without that function call, we don't have all the variables set for this conditional, which in turn means that we don't set
${_PYTHON_PREFIX}_Development.Module_FOUND
toTRUE
.
I am not sure why the addition of LIBRARY
is inside a Windows-specific conditional, and I don't know if removing it causes issues in non-Windows environments other than my own, but I can confirm that removing it fixes my issue (!7406 (closed) contains that proposed fix). If that fix is problematic, I could use some guidance on what alternate path the code is supposed to follow on my non-Windows system in order to correctly find the desired component. I'm happy to provide any additional context for debugging.
