Setup script for TinyUSDZ Python ABI3 binding
|
|
|
|
This builds a Python extension module using the stable ABI (limited API)
|
|
for Python 3.10+. The resulting wheel is compatible with all Python versions
|
|
3.10 and later without recompilation.
|
|
|
|
Usage:
|
|
python setup.py build_ext --inplace
|
|
python setup.py bdist_wheel
