System preparation before building

To avoid errors, you must meet two requirements:

1. Disable third-party network tools:

   • DPI bypass tools

2. Enable Long Paths support in Windows:

   • This is the system limit of 260 characters for a file path
   • Note: In newer versions of Windows 10/11, this setting is often enabled by default. You can check it by running the command fsutil behavior query LongPathsEnabled in a terminal with administrator rights. If it outputs 1, it is enabled
