So if I use the attached CMakeLists.txt then everything seems to work. My
setup is a conda setup and I am using an environment arrow-release-4 which has
arrow-cpp installed (which is where those shared libraries in the attached
CMakeLists come from). I get the following output.
```

My suspicion is that the issue is here:
```
target_link_libraries(helperfuncs PRIVATE arrow_static) #arrow_shared
target_link_libraries(helperfuncs PRIVATE
PYTHONPATH/site-packages/pyarrow/libarrow_python.so.400)
```
It appears you are linking arrow statically but linking arrow_python as a
shared library. I'm not sure if that is valid or not. Even if it is valid
there is no static arrow library supplied by pyarrow. That means that
find_package must be finding Arrow from some other location. The end result is
some kind of library ABI mismatch.
I'm still getting up to speed on cmake myself but what happens if you try...
```
target_link_libraries(helperfuncs PRIVATE
PYTHONPATH/site-packages/pyarrow/libarrow.so.400)
```
I'm pretty sure at this point you can get rid of `find_package(Arrow
REQUIRED)` too.
