Thanks for this!

The action is failing with this cryptic message:

AttributeError: module 'PyImath' has no attribute 'dynamic_metadata'

I think this is from the step that dynamically computes the version string. You're missing the sci-kit script that computes the version. Try making a local copy of this: https://github.com/AcademySoftwareFoundation/openexr/blob/main/src/wrappers/python/openexr_skbuild_plugin.py

This runs cmake to determine the version, rather than hard-coding the version into the pyproject.toml. It's invoked via the line in pyproject.toml that says dynamic = ["version"]

I'm not 100% sure that Imath's CMake currently returns the right string to extract the version, so it might need some further tweaking.

Double check which of these variables actually exist. I think

IMATH_BUILD_EXAMPLES
IMATH_BUILD_TOOLS
IMATH_INSTALL_TOOLS
IMATH_FORCE_INTERNAL_DEFLATE
IMATH_FORCE_INTERNAL_IMATH
IMATH_TEST_LIBRARIES

don't exist, that was copy/paste from OpenEXR.

@cary-ilm sorry for delay, so I am facing the following issue

any device how I can found version dynamically ?
