If you want to use the native versions of Git, Python, or CMake you can remove
them from the above pacman command and install them from another source. Make
sure that they're in your Windows PATH, and edit the relevant `mingw[32|64].ini`
file in your MSYS2 installation directory by uncommenting the line
`MSYS2_PATH_TYPE=inherit` to include them in your MSYS2 PATH.
Using Windows native Python can be helpful if you get errors when building LLVM.
You may also want to use Git for Windows, as it is often *much* faster. Turning
off real-time protection in the Windows Virus & Threat protections settings can
also help with long run times (although note that it will automatically turn
itself back on after some time).
