How to use CMake with third party dependencies for building conda packages with pybind11?

[lwygzh]

Hi,

I want to use pybind11 to bind a C++ package that depends on third-party libraries like Eigen and Boost and build it into a conda package. I was wondering if there is an example of doing so? I took a look at the scikit-build example that also does not depend on third-party libraries.

@henryiii do you have any insights on this matter?
