This is great and we can use this. However here are some things that need changing.

First, since pkgconfig doesn't come with Python, this package needs to be  noted as a dependency (the "install_requres" parameter) in setup.py.

Second, by using this we will limit the range of Python to 2.6+ and 3.3+. I'm okay with that, but again setup.py needs to note that.

As for the mechanics, please fork the code on github
https://github.com/rocky/pycdio and put in a pull request (PR).

Thanks.

When trying to build pycdio-2.1.0 on FreeBSD 11.3 with python3.6, the compilation of pycdio_wrap.o fails because it can't find "cdio/cdio.h".

The generated compiler call is "cc -Wno-unused-result -Wsign-compare -Wunreachable-code -DNDEBUG -O2 -pipe -fstack-protector-strong -fno-strict-aliasing -fPIC -Ib'/usr/local/include' -I/usr/local/include/python3.6m -c swig/pycdio_wrap.c -o build/temp.freebsd-11.3-RELEASE-p3-amd64-3.6/swig/pycdio_wrap.o"
which fails because the parameter "-Ib'/usr/local/include'" is evaluated to "-Ib/usr/local/include".

If the include_dirs list is decoded from utf-8 like the libraries list then the compiler call runs successfully. But a traceback with a TypeError occurs in unixccompiler ("TypeError: must be str, not bytes"). The hint on https://pypi.org/project/pycdio/ to exchange the unixccompiler.py with a recent version didn't help but decoding the runtime_lib_dirs list from utf-8 would help...

Since there was a comment with "FIXME" above the pkg-config subprocess code, i tried to find a more elegant solution and used the pkgconfig python package.

The patch is attached.
