How do I enforce that pybind11 be installed before my package

I believe that's how to interpret the error below:

~/Documents/GarNet(master*) » pip install pcst_fast
Collecting pcst_fast

Collecting pybind11>=1.7 (from pcst_fast)

Not sure how this is related to pybind11. pcst_fast.h is not a pybind11 header file.

True, I'm using pybind11 for my pcst_fast package. I've used this repo's setup file as a model to build my package, and I can successfully install with setup.py locally, but this fails on pip -- and I believe the reason is because locally I pre-install pybind11 with a pip install pybind11.

So the issue I'm logging is: my claim is this repo is not a correct example of how to build a python package with pybind11 for pypi, or I've messed up some other way. The issue I think I'm having is that, when I put this on pypi, it seems to try to install my package before pybind11, which won't work since my package is all c. @wjakob

@wjakob this might be a copy of #16
