Change Executable Icon for command line:

• Based on https://github.com/fatrolls/IconChanger
• Only the 1st image of the .ico file is added to the .exe
• Tested on Windows 10 Pro 64bit - Version 2004 / build 19041.685 / locale en-US

Compiled with MSYS2/MinGW-w64:

$ gcc -o cei cei.c -s -O3 -Wl,--gc-sections -fno-asynchronous-unwind-tables -nostartfiles --entry=cei

Usage:

> cei PATH\TO\ICO PATH\TO\EXE [PATH\TO\NEWEXEWITHICO]

• If [PATH\TO\NEWEXEWITHICO] is ommitted, cei.exe edits the original .exe located at PATH\TO\EXE
• If [PATH\TO\NEWEXEWITHICO] is passed, cei.exe makes a copy of the original .exe to PATH\TO\NEWEXEWITHICO, and edits this copy

Notes:

• !! Some executables wont work anymore after changing their icon.. !!
• ..So make a backup beforehand and/or pass [PATH\TO\NEWEXEWITHICO] as a 3rd argument
