Subject : Fix: Incorrect BufferOverflow library selection for Windows 7 targets
Problem: > When using WDK 10 to target Windows 7 (WINVER 0x0601), FindWDK incorrectly links against BufferOverflowFastFailK.lib if it exists. This causes a BSOD (Bugcheck 0 / STATUS_BREAKPOINT) on Windows 7 because it does not support the FastFail instruction introduced in Windows 8.
Solution:
Changed the logic to select the buffer overflow library based on the target WDK_WINVER.
If WDK_WINVER < 0x0602 (Win8), it now explicitly prefers BufferOverflowK.lib.
This aligns with official Microsoft documentation Building Drivers for Different Versions of Windows regarding driver compatibility for older Windows versions.
