Is anyone aware of any tricks that can be played with tools like
`readelf`, `nm` or `dlopen` / `dlsym` in order to statically determine
what version of numpy a fully-compiled C extension (for example, found
inside a wheel) was compiled against? Even if it only worked with
relatively new versions of numpy, that would be fine.
I'm interested in creating something similar to
https://github.com/pypa/auditwheel that could statically check for
compatibility between wheel files and python installations, in
situations where the metadata about how they were compiled is missing.

NPY_ABI_VERSION is exposed in C as PyArray_GetNDArrayCVersion and
NPY_API_VERSION is exposed in C as PyArray_GetNDArrayCFeatureVersion.
These are not incremented for every NumPy release, see the documentation
in numpy/core/setup_common.py.
The numpy.__version__ is determined by a python file numpy/version.py,
which is probably what you want to use.
There is an open Issue to better reveal compile time info
