Programatically get Python cflags and libs for compiling C extension

Question

Prelude

In linux one can run:

$ pkg-config --cflags --libs python3

and get as result:

-I/usr/include/python3.5m -lpython3.5m

Problem

I want to get this result programatically from a Python script in both Linux and Windows.

Motivation

I have several Python scripts that I want to compile as C using cython. I'm trying to create a Python script that would handle this compilation process.

Having three files: exec.py, apkg.py, bpkg.py; the desired execution order would be:

cython --embed exec.py
cython apkg.py
cython bpkg.py
gcc -shared -fPIC -O3 -I/usr/include/python3.5m -lpython3.5m apkg.c -o apkg.so
gcc -shared -fPIC -O3 -I/usr/include/python3.5m -lpython3.5m bpkg.c -o bpkg.so
gcc -c -O3 -I/usr/include/python3.5m -lpython3.5m exec.c
gcc -o exec exec.o

And exec would be a compiled executable that needs apkg.so and bpkg.so in the same directory to run.

Posible answers

Use python-config: as of version 3.5, the Python installer for Windows (tried in 64 bits) does not include python-config
User pkg-config: again, Windows compatibility issue.

I know about cmake, I could create a custom command for the cython phase but... to find Python wouldn't it need pkg-config? — Simón Oroño, Oct 29 '15 at 03:10
Well not necessarily, python is installed in a known location on Windows AFAIK. And probably *cygwin* or *MinGW* ship *pkg-config* with them. — Iharob Al Asimi, Oct 29 '15 at 03:13
Actually, that location changed from version 3.4 to 3.5 (C:\ to C:\Program Files). I'm trying to avoid all this and find a standard way to do it from a simple Python script — Simón Oroño, Oct 29 '15 at 03:23
Well I just tried to guide you in a very general way. I am not an expert, but I believe there is some *setuptools* module shipped with every python distribution, it might be what you need. — Iharob Al Asimi, Oct 29 '15 at 03:28
