# powershell script to parse devkit version and install Zig
# assume: 1. devkit in dir devkit, zig in dir zig in same dir
#         2. cmake installed (download possible on https://cmake.org/download/)
#         3. ninja installed (pip install ninja) + in path
#         4. powershell scripts executable (execution in shell):
#         Get-Content bZig.ps1 | PowerShell.exe -noprofile -
