Trouble running cargo test on mac OS

[jeremiah-corrado]

I'm seeing the following build error when trying to run cargo test on Mac OS with V1.0.2:

    Updating crates.io index
error: failed to select a version for `kifmm-fftw-src`.
    ... required by package `kifmm-fftw-sys v0.2.0 (/Users/jerey/Documents/kifmm-review/kifmm/fftw-sys)`
versions that meet the requirements `^0.2.0` are: 0.2.0

the package `kifmm-fftw-src` links to the native library `fftw3`, but it conflicts with a previous package which links to `fftw3` as well:
package `kifmm-fftw-src v0.2.0 (/Users/jerey/Documents/kifmm-review/kifmm/fftw-src)`
Only one package in the dependency graph may specify the same links value. This helps ensure that only one copy of a native library is linked in the final binary. Try to adjust your dependencies so that only one package uses the `links = "fftw3"` value. For more information, see https://doc.rust-lang.org/cargo/reference/resolver.html#links.

failed to select a version for `kifmm-fftw-src` which could resolve this conflict

Alternatively, when trying to run cargo test on main, I'm not seeing the above error, but I do get a number of build failures (when building kifmm-fftw-sys) along the following lines:

error[E0432]: unresolved import `green_kernels::types::EvalType`
 --> kifmm/src/fmm/builder.rs:4:52
  |
4 | use green_kernels::{traits::Kernel as KernelTrait, types::EvalType};
  |                     

Note: I'm on an M1 Mac, I'm on the latest release of Rust, and I've installed FFTW using Homebrew.

Any help diagnosing what might be going wrong here would be appreciated!

Hi, this library builds and links a version of fftw, so you should avoid linking your own. The reason for this is we use custom build options for fftw, and only wrap small portions of the library.

[skailasa]

If you have fftw in your LD_LIBRARY_PATH, you should update it so that the homebrew version is not seen by Rust.

PS: I would also recommend running cargo build/cargo build --release, before running cargo test.
