I have a python library in C++ that I can install via pip provided all libraries are installed on the system. I want to make it easier for users so I want a conda package that would also install the libraries required by my library to run : libblas, liblapack in particular.

I can build the package with conda build, and I do get a functional library. However, it does not ship with the required libraries (libblas, liblapack). So if I install the *.tar.bz2 in an environment without those libraries, my library will not work.

How to get my library to also automatically install the required libraries (libblas and liblapack) in the env ?

Here is the (relevant part) of the meta.yaml file :

requirements:
  build:
    - cmake>=3.14
    - make 
    - {{compiler('cxx')}}
    - libblas
    - liblapack
    - pybind11
  host:
    - pip
    - python
    - libblas
    - liblapack
    - pybind11
  run:
    - python
    - libblas
    - liblapack
    - pybind11
