Hi Jonatan,

Adam and I have been bouncing ideas back and forth and he helped me get to
a working setup, most recently with Seth's new_python branch but I think
this should work with current master too.

The key point is that we don't yet have a working way to use your system
Python (but Adam has ideas on that and is working on it)

So, the steps that worked for me are:

1) Use kicad-mac-builder to set up the dependencies.
As described in the readme:
https://gitlab.com/kicad/packaging/kicad-mac-builder
run ./build.py --target setup-kicad-dependencies

Note: this will install everything, including wxwidgets, wxpython, etc.
There isn't currently a way to skip some if you already have them built
outside kicad-mac-builder.
Really you and I mostly need Python out of this, as it's the only
dependency that is hard to manage right now.

2) At the end of its run, build.py will spit out a lot of suggested CMake
flags.  Save these, and then do a merge with your current CMake flags that
you are building with.
In particular, you'll want to carry over the flags that point at the Python
framework created by build.py.

3) Use Adam's wrangle-bundle script to fixup the installed bundle.
Obtain that from https://gitlab.com/adamwwolf/dyldstyle and install it (I
used the venv method suggested by Adam in the readme)
Run something like wrangle-bundle --python-version 3.8 --fix
path/to/KiCad.app

4) At this point, your build should work and make install should also work
(at least it did for me).  Please let us know if you don't have success

5) There are additional steps and complications if you want to run and
debug targets without first doing make install, as is possible on other
platforms.  I have figured out a workaround that makes this work, but it is
not awesome, so Adam and I are discussing an easier route.

We will update the documentation accordingly, things are just moving
quickly at the moment and we're trying to have them settle down in a way
that is easy to follow for developers.

Best,
Jon
