CMake: Force x86-64-v2 instruction set for better compatibility
Enforce x86-64-v2 instruction set level to prevent compatibility issues
on systems that default to higher ISA levels (v3/v4). This fixes crashes
reported on certain Linux distributions like CachyOS that force higher
instruction set levels by default.
The fix:
- Sets -march=x86-64-v2 for both C and CXX flags
- Adds compile options to ensure system defaults don't override
- Explicitly disables v3 and v4 instruction sets
- Only applies to x86_64 architectures
Credits to Alex&Indie for identifying the ISA level compatibility
issue.
Fixes: Linux Compilation.
