Building:

• Install Python's SetupTools and Wheel and then;
• We compile the catool_fast.c module with MSVC Python Build Tools:

py -3.14 -m pip install --upgrade pip setuptools wheel
py -3.14 setup_catool_fast.py build_ext --inplace

• Finally we package it using PyInstaller.

py -3.14 -m PyInstaller --onefile --windowed --name CATool --icon icon.ico --add-binary "catool_fast.cp314-win_amd64.pyd;." --add-data "icon.ico;." CATool.py
