Installation: missing zlib library #90

What did you do?

Tried to install pillow-simd on a fresh environment:

$ pip install pillow-simd

What did you expect to happen?

Installation goes successfully.

What actually happened?

Got an error:

...
The headers or library files could not be found for zlib,
a required dependency when compiling Pillow from source.
...

I've verified that I have the zlib library installed:

$ brew list | grep zlib
zlib

What are your OS, Python and Pillow versions?

OS: macOS 10.14.6
Python: 7.7.8
Pillow: No pillow is installed. I'm trying to install Pillow-SIMD-7.0.0.post3

This is not SIMD-specific. Please follow this instruction: https://pillow.readthedocs.io/en/stable/installation.html#building-from-source

If you still have an issue with building Pillow from sources, fill a report.
