I got it to work! CBLAS is not being included with `find_package(BLAS REQUIRED)` in the `basix/cpp/CMakeLists.txt` file.

To fix that, I found my answer [here](https://github.com/davisking/dlib/issues/154#issuecomment-240651490): I added

```auto
set(BLAS_LIBRARIES "-lcblas;-lblas")

```

above `target_link_libraries(basix PRIVATE ${BLAS_LIBRARIES})`

After installing the package, I renamed `basix/test/test_numba.py`, and all tests passed.
