Use of `Eigen` package throws `'mmintrin.h' file not found` error

Hi, thank you for the package!

This issue is potentially related to #30. I tried wrapping the code I want before even trying the tutorial. Then I realized even the hello world example fails.
I'm trying to create a Julia wrapper for this ghostbasil package, but I seem to be running into weird issues with Eigen.

Here is my ghostbasil.wit:

module_name         = "GhostBASIL"
export_jl_fname     = "GhostBASIL-export.jl"
module_jl_fname     = "GhostBASIL-generated.jl"
include_dirs        = [ "/Users/biona001/.julia/dev/ghostbasil/ghostbasil/include/ghostbasil" ]
input               = [ "matrix/block_group_ghost_matrix.hpp", "matrix/block_matrix.hpp", "matrix/ghost_matrix.hpp", "matrix/group_ghost_matrix.hpp", "optimization/basil.hpp"]
extra_headers       = [ "/usr/local/include/eigen3/Eigen/Core", "/usr/local/include/eigen3/Eigen/SparseCore"]
cxx-std             = "c++17"

Running wrapit:

$ wrapit ghostbasil.wit --force --verbosity 1

I can't find much information regarding 'mmintrin.h' file not found error. Any help/insights would be highly appreciated.
