This is exactly how it's done right now with KiCad-Winbuilder, except it does not build locally. KiCad-Winbuilder downloads the zip and "installs" Python-a-mingw-us locally. When KiCad is built, the executables are arranged locally in the standard install format (i.e. kicad/bin kicad/doc kicad/share, etc.). Python-a-mingw-us is copied to kicad/bin, and PYTHONHOME is set to kicad/bin. You can install Python-a-mingw-us alongside Python without a problem. Generally it is recommended to install in the default location of c:\python\2.7.4 - this means you do not need to supply a PYTHON_ROOT_DIR setting for the CMake scripts that want to use it. The modified FindPython*.cmake modules are included in the KiCad source. To switch between python versions you need to control your PATH environment variable so the Python-a-mingw-us python is visible first. Then you can set PYTHONHOME to the path of python. I have both Python and Python-a-mingw-us installed. Python-a-mingw-us doesn't touch the registry, it just copies files into your chosen path. You can simply grab the zip and extract. The Python-a-mingw-us installer doesn't currently set PYTHONHOME. There is a new installer to release, which I will do soon once I've got a debug build sorted out. Then there'll also be a source archive too so you can debug Python-a-mingw-us with source. You can set a source file path replace rule in GDB so that the source file references work wherever you've extracted the source. Best Regards, Brian.
